Low Profile
Datacom/Telecom Applications
The N-Series is a full-featured hydraulic-magnetic circuit breaker
packaged in an innovative low profile design to meet the smaller
size requirements of datacom/telecom power distribution units
and rack systems. Its features include easy access line and load
terminals with UL 489 compliant sliding terminal barriers, an
optional current transformer capable of sensing current down to
a level of 1%, and a patented flush rocker actuator with push-toreset guard to protect against inadvertent actuation. The N-Series
is available as a one or two pole configuration with ratings from
1 to 30 amps, up to 277VAC for one pole or 120/240VAC for two
poles with a max IC of 22,000 amps.
