Arc Fault Protection

Mors Smitt UK Ltd Stand: 5-E51/ DAC

Arc fault protection for the fast clearance of arcing faults on BUS bars & within metal clad switchgear & associated cable boxes. The arc is detected using an optical sensor & the signal input to a protection device which alsomonitors the load current on the system.

 

A trip signal can be achieved in less than 10msusing arc detection only or within 15ms when using overcurrent check. This is considerably faster than a traditional IDMT overcurrent relay & provides additional protection from the onset of arcing faults with relatively low fault currents.
