4 Pole Isolating and Earthing Unit - 415V AC 250A

 

Isolating and Earthing Unit for a nuclear research centre Magnet power supply.

Consisting of an on-load Contactor, a motorised off-load Disconnector, fuses and a control circuit.

Isolation of medium voltage magnet supplies, 3.3kV, for maintenance.

2 Pole Earthing Changeover Switch Panel (twin isolators)

 

250V DC supply is derived from the Magnet Power Supply.

The 250V DC is fed to the respective 2 pole disconnector, via 2 x 150mm2 cables coming in from the base of the enclosure

When the Disconnector is moved to the earthed position the outgoing supplies to the respective magnet are earthed and can be interlocked, making them safe for maintenance.

Tool operated doors prevent access to sections containing 250V DC
