Automatic circuit breaker is installed into the separate compartment of the box. A front panel of the automatic circuit breaker goes through the door’s cut out and is available for management and maintanance. Depending on the cabinet’s configuration the door can be as general as for every cabimet’s compartment.
There are 2 installation methods of the automatic circuit breaker 3WL possible:
- fixed performance - automatic circuit breaker is fixed in the cabinet;
- draw out performance - automatic circuit breaker is installed into the basket with the draw out device, which is fixed in the cabinet.
Secondary circuit equipment is placed in the compartment of additional cabinet’s equipment.

Cabinets of the OFW type (draw out type of module)
Cabinet for the cable feeders or drive with the draw out modules assures high ease of use and optimal safetyand high level of the device readyness. Quick repalcement and module modernization are possible due to appliance of the draw-out principle . Any module can be additionally supplied or replaced.
The draw out construction SIVACON assures the highest level of equipment readiness.
A vertical bus system for the plug-in contacts goes through in the back side of the cabinet and is protcted against contacts by a special housing (IP20).
Versions of the cabinet’s structures with the draw-out modules according to the type of connection.
A draw-out module is a combination of the low-voltage switching devices (automatic circuit breaker, contactor, relay), which are used for the energy distribution (cable feeder) or for the equipment’s electromotor control (motor feeder). This equipment is placed on the wiring board inside the draw out module. On the front of the draw out module can be placed the control devices (control buttons, signal lamps) and measuring instruments (ampere-meter, voltmeter).
Depending on the content of the equipment and its size draw out modules are distinguished by height: 100mm, 150mm, 200mm, 300mm, 400mm, 500mm and 600mm.
100mm height draw out module (motor feeder)
As a rule draw out modules are provided with the electronic control and motor protection relay SIMOCODE PRO produced by SIEMENS, which consists of: basic module, current and voltage measuring modules, operator panel, expansion modules: digital I/O, analog input, earth-fault module. In this case electromotor control is carried out according to the throwaway code included to the basic module both in the standalone mode and in the PROFIBUS DP net.

Cabinets of the OFPM type (plug-in modules)
Cabinet for cable feeders or motor with the plug-in modules is a cost-effective alternative of the cabinets with the draw out modules. Quick module replacement without a shutdown of the cabinet is possible due to the plug-in contacts on the supply side. Any module can be additionally supplied or replaced. Plug-in structure SIVACON assures excellent savings, reliability and flexibility. Vertical bus system for the plug-in contacts goes through in the back side of the cabinet and is protcted against contacts by a special housing (IP20).

Cabinets of the PFC type (reactive power compensation)
Reactive power compensation cabinet PFC is used for reactive energy compensation and keeping of power factor (cos ϕ) on the target level; this reduces load on the transformers and cables, transmission losses and cost of electricity. Cabinets consist of the separate compensation modules, which allows to add step by step the rated power of the compensation device.
On/off control of the condenser is carried out by the special programmable controller produced by MODL, Germany.
Compensation module consists of: protection device (fuses, automatic circuit breakers), contactors with contacts of the advanced switching and current limiting resistors and condensers.
Depending on the load type in the electric circuits of the consumer compensation cabinets can be with and witout trottle.
Compensation cabinets without trottle are used for the centralized compensation of the reactive power in the linear electronic circuits. Maximal power of the one cabinet without trottle can be equal to 500kVar.
Compensation cabinets with trottle are used for the centralized compensation of the reactive power in the nonlinear electronic circuits (>20% from total load). Maximal power of the one cabinet with trottle 5.67% can be equal to 400kVar, with trottle 7% - 300 kVаr.

Cabinets of the CCS type (free-design cabinets)
Free-design cabinets are used for installation in them of different components and can be used for solving of different tasks. For example, for placement of controllers, or frequency inverters, a lot of low-power consumer devices etc.
Cabinets can have different configuration:
with and without main busbar;
with and without vertical busbar;
with one or several wiring boards.
Cable connection is performed from the front of the cabinet.
