The low voltage switchgear distributes incoming electrical power among the circuits shown in the installation scheme. Cabinets contain busbars, switching devices, feeder units and the associated control connections. Fixed and withdrawable arrangements provide different ways to organize those functions. Drawer-based units can separate outgoing feeders within a modular cabinet layout. Cable connections and cabinet interfaces then join the lineup to the wider distribution system. GCS, GGD and MNS families have different listed ratings, so the selected assembly must follow the required voltage, current and operating arrangement. The enclosure and circuit schedule are considered together when the board is prepared.

Main Applications

The low voltage switchgear manages building feeders and workshop distribution boards.

Motor-control centers can use withdrawable units to organize several motor circuits.

Compensation circuits can share a coordinated cabinet lineup with incoming and outgoing feeders.

Cabinet lineups can separate incoming power, outgoing feeders and motor circuits so the electrical-room arrangement follows the complete distribution scheme.

Why choose us

Our low voltage switchgear production team reviews cabinet selection and feeder arrangements together. Workshop resources support enclosure preparation, component installation and final assembly. We check the requested drawer layout against the electrical drawings before packing the lineup. This gives purchasing teams a consistent reference for cabinet sequence, connection details and repeat feeder units, especially when several distribution boards belong to one installation.

Please retain the incoming and outgoing circuit references on the approved scheme so cabinet assembly and the site cable schedule use the same feeder identification.
