Hydraulic Magnetic Circuit Breaker
Space Saving Design for Datacom/Telecom
Optional Integrated Current Transformer
The L-Series high performance, hydraulic-magnetic
circuit breaker is ideal for the confined spaces of
datacom/telecom power distribution units and rack
systems. The space saving design features an optional
current transformer with a 1% sensitivity tolerance for
simple monitoring of the power consumed by storage
and routing devices. A patented flush rocker actuator
and optional push-to-reset guard protect against
inadvertent actuation. The L-Series is rated from 0.1-32
amps, up to 240VAC with a max IC of 5,000 amps.
