Your benefit

  • Safety by connected, test and disconnected position with the door closed

  • Optimum cubicle width for every circuit-breaker size

  • Ideal space conditions for cable connection, for every size

  • Design verified connection to SIVACON 8PS busbar trunking systems

User-friendly with safety

The cubicles for 3W./3V. circuit breakers cater for personal safety and long-term operational reliability. The incoming feeder, outgoing feeder and coupling cubicles in circuit-breaker design are fitted with 3W. air circuit breakers in withdrawable or fixed-mounted design or, alternatively, with 3V. molded case circuit breakers.

Since there are generally many consumer loads downstream from these cubicles, the personal safety and operational reliability of these are of particular impor- tance. SIVACON S8, with its components of the circuit-breaker design, meets all these requirements in compact and safe manner.

Moving to the connected, test or disconnected position with the 3W. air circuit breaker takes place with the door closed. Design verification by tests in accordance with IEC 61439-2 also guarantees a high level of safety for all sizes.

Cost-efficient solutions

As a compact version with a cubicle width of just 400 mm, the cubicle with 3W. air circuit breaker is perfectly suitable for current ratings up to 2,000 A. For a cost-efficient installation, the cir- cuit-breaker cubicle with a width of
600 mm offers enough space for up to three circuit breakers. In this version,
the connection is made at the rear.

Cubicles in circuit-breaker design can be equipped with forced cooling. The use of fans considerably reduces the circuit- breaker derating caused by operational power loss. Cubicle properties such as degree of protection or a high form of internal separation are not restricted thereby.

Flexible for individual requirements

The cubicles consist of separate functional compartments. In the cable or busbar connection compartment,
the circuit-breaker design offers optimal connection conditions for every size.

There, cables or SIVACON 8PS busbar trunking systems can be connected with design verification. The busbar trunking system connection units, specially developed for SIVACON S8, are an integral component of the cubicles in circuit-breaker design.

 

The auxiliary device compartment offers ideal space conditions for the switching devices provided for control and monitoring. They are arranged on an auxiliary device holder which can be separated from the power section. Depending on the position of the cable or busbar connection compartment, the auxiliary device holder can be installed at the top or bottom.

Universal Design Forced Ventilation 3.jpg

Wide cable connection duct for easy installation

Universal Design Forced Ventilation 2.jpg
Universal Design Forced Ventilation 1.jpg

The universal mounting design with forced ventilation enables the installation of withdrawable units for devices with extremely high power loss, such as frequency converters.

Flexible and space-saving

The functional assemblies can be combined at will, allowing for a space- saving installation of your switchboard. The 400 mm or 600 mm wide cable compartment on the right side of the cubicle offers cable brackets for fastening the cables. In universal mounting design, the cables can also be connected at the rear, which makes the lateral cable com- partment unnecessary, thus reducing the cubicle width to 600 mm. The vertical distribution busbars are arranged at the rear left in the cubicle. The profile busbar or flat copper design allows for tap-offs in the smallest of grids. Cables, wires or busbars can also be connected without any need for drilling or punching – opti- mal flexibility for later extensions.

Extended mounting options

Cubicles in universal mounting design can be provided with forced ventilation to enable the installation of devices with extremely high power loss in withdraw- able design. The heat is dissipated by fans via a separate air duct. The fans are sized so that heat removal of the with- drawable unit is ensured even if one of the fans fails.

Communication

Communication via PROFIBUS DP, PROFINET or Modbus offers all the benefits of extensive control functions and analysis options.

Plug-in design with 3NJ62.jpg

Plug-in design with 3NJ62 switch-disconnectors with fuses

Fixed-mounted design – modular and cost-efficient

The fixed-mounted switching devices are installed on modular device holders. These can be equipped with circuit breakers or switch disconnectors with fuses.

Cable connection is made directly at the device or, in cases of higher requirements, at special connection terminals in the cable compartment. For individual equipping, the system offers freely assignable device holders.

Plug-in design – flexible modifications

3NJ62 or SASILplus (JEAN MÜLLER) switch disconnectors with fuses can be installed in the bottom 600 mm of the device compartment. They are equipped with a plug-in contact on the supply/line side. This means that the switch discon- nector can be replaced or modified without de-energising the cubicle.

Withdrawable key.jpg

Simple and safe operation of the withdrawable units behind closed doors

Coding.jpg

The mechanical coding of the withdrawable unit prevents any confusion of withdrawable units of the same size.

Withdrawable design – ergonomic and compact

When requirements are frequently changing, e.g. modifications in
motor rating or the connection of new consumer loads, the withdrawable design offers the flexibility needed. Withdrawable units can be modified or retrofitted with ease, and without de-energising the cubicle.

Regardless of whether small or normal withdrawable units are used, the size is optimally adapted to the required power rating, thus allowing to reduce the size of the switchboard to a minimum. The compact small withdrawable units are particularly useful here.

With small withdrawable unit sizes of 1/4 (up to four withdrawable units per compartment) and 1/2 (up to two with- drawable units per compartment), as well as with normal withdrawable units with heights starting from 100 mm, very high packing densities can be achieved, with up to 48 withdrawable units per cubicle for space-optimised installation.

MCC On

Both power and control contacts are closed.

MCC Off

Maximum isolating distances.

MCC Test

No-load testing of the withdrawable units.

Moving to the withdrawable unit positions behind closed door

Safe operation of the withdrawable units
Withdrawable units of all sizes are equipped with integrated operating error protection and a uniform, clear indication of the withdrawable unit positions. Moving to the test, disconnected or connected position takes place with the door closed and without eliminating

the degree of protection.

 

In addition to the main switch, the dis- connected position of the withdrawable units can also be locked for additional safety. A coding of the withdrawable unit prevents any confusion of withdrawable units of the same size.

The patented withdrawable unit contact system has been conceived to be user- friendly and particularly wear-resistant. In order to protect against damage, in the disconnected position all parts of the withdrawable units are located within the contours of the withdrawable units. The withdrawable unit compartments have isolating distances on the incoming and outgoing sides. No connection work is required inside the withdrawable unit compartments.

Cost-efficient overall system

In a network, reactive power is caused by inductive, linear consumer loads such as motors, transformers or reactors, as well as by inductive, non-linear consumer loads such as converters, welding apparatus, arc furnaces or UPS systems. Depending on the consumer load structure, the reactive power compensation is equipped with choked or unchoked capacitor assemblies. The controller assembly has an electronic reactive power controller for door installation. The multifunction display is used to set the desired target cos phi from 0.8 ind to 0.8 cap. Network parameters such as U, l, f, cos phi, P, S, Q and harmonics are displayed.

The capacitor assembly (up to 200 kvar) with MKK capacitors has a fuse switch- disconnector, capacitor contactors, discharge devices and filter reactors. The switch-disconnector assembly can optionally be used for the central safety isolation of the integrated capacitor assemblies.

Flexible design

The reactive power compensation cubicle can be integrated into the switchboard directly and with design verification. In this case, additional protection mea- sures and cable connections between the switchboard and the reactive power compensation are not required when these are installed separately. The entire height of the device compartment is available for the installation of the controller, capacitor or group-switch assemblies. The device compartment is closed by means of a cubicle-height door with ventilation openings.
