High Speed Circuit Breaker type IR6000 with Permanent Magnet Latch
The IR6000 Permanent magnet latch series are fixed or withdrable, single pole, magnetic blow-out, trip free, air circuit breakers.
The closing mechamism is an independent motor operated type.
The breaker is held closed by a permanent magnet device and is equipped with a direct acting over – current trip device which may be either unidirectional or bidirectional.
The Breaker conforms to ANSI C 37-14, ANSI C 37-16 and EN50123 Standard.
