N-Series
N-Series
CIRCUIT BREAKER
Carling Technologies’ high-performance N-Series hydraulic-magnetic circuit breaker is ideally suited for the rigors
and conned spaces of telecom and datacom power distribution units and rack systems. Its innovative, low prole
design features easily accessible load and line terminals and sliding barriers for effortless installation.
With the integration of an optional current transformer, the N-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 efciency.
A patent pending, ush-rocker actuator and push-to-reset guard offer additional protection against accidental switching.
