Structure of the switchboard
Circuit breaker compartments
The circuit breaker compartments, situated in the front part of the switchboard and accessible by means of a hinged door (with or without door lock depending on the construction type used), can house one or more circuit breakers of the air, moulded-case, or modular type. The circuit breakers installed inside the compartment can be in fixed, removable, or withdrawable version.
Instrument compartments
The instrument compartments are situated in the front part of the switchboard and accessible by means of a hinged door. They can contain measurement instruments and equipment, protection relays, control and signalling devices. This auxiliary equipment can also be installed in the circuit breaker compartments to create an all-in-one type functional unit.
Main busbar compartment
The main busbars are situated in the middle part of the columns (space of approximately 500 mm in depth). They distribute the power supplies to the distribution busbars. They can be positioned, in height, in the upper, middle, or lower part of the columns depending on the geometry of the system of busbars to be created.
Distribution busbar compartment
The distribution busbars are situated in the rear part of the columns (space of approximately 500 mm in depth). They distribute the power supplies to the functional units of the switchboard. They can be positioned, in height, in the upper, middle, or lower part of the columns depending on the geometry of the system of busbars to be created.
Power connections compartment
The power cables compartments are always positioned in the rear part for access to the connections from the back.
