Hydraulic Magnetic Circuit Breaker


The L-Series high performance, compact hydraulic- magnetic circuit breaker is ideally suited for the rigors and confined spaces found in today’s telecom/datacom power distribution units and rack systems. It provides best in class performance in an innovative low profile, space saving package complementing the overall spatial objectives required by telecommunications and data-communications systems designers in their quest to reduce the overall size of equipment, while increasing transmission capacity. With the integration of an optional current transformer, the L-Series is capable of sensing current down to a level of 1%. This optional capability provides precise current monitoring and reporting required for back billing of the actual power consumed by datacenter storage and routing devices. This feature also facilitates load adjustments and maximizes efficiency.

Further, a patent pending flush rocker actuator design and optional push-to-reset guard offers additional protection against accidental switching.

Number of poles: 1-3 poles;. Max current/voltage ratings: .1-32A, 120/240-240VAC. Max interrupting capacity: 5000 Amps.
