M-Series
Circuit Breaker
The M-Series is a low cost, miniature hydraulic/magnetic
circuit breakers ideally designed for demanding
applications requiring space saving features, aesthetics and
snap-in front panel mounting.
Its newest design features a compact, space saving,
vertically mounted parallel pole configuration, which
is UL489A listed up to 50 amps and is well suited for
telecommunication equipment fitting in one rack unit.
Furthermore, it features two uniquely designed terminals
that provide the highest level of balanced circuit
protection.
In addition, these circuit breakers feature various styling
options allowing for design flexibility. They are available
in choices of rocker actuator styles and colors, including
paddle and baton style handle actuators, push-to-reset
and push-pull pushbutton actuators, Visi-Rocker two color
actuators as well as non-illuminated or illuminated rocker
versions with LED or neon bulbs. The exclusive Rockerguard
bezel helps prevent inadvertent actuation and wiping
contact design insures long-term reliability. The M-Series
circuit breakers are available in 1 & 2 poles or parallel poles,
0.02 to 50 amps, up to 250VAC or 80VDC with choices of
time delays, terminals, panel hardware, actuator styles,
colors, and imprinting.
Features:
Parallel pole configuration well suited for one rack unit
Compact design

All M-Series Circuit Breakers will
trip on overload, even when
actuator is forcibly held in the ON
position.
The actuator moves positively
to the OFF position when an
overload causes the circuit
breaker to trip.
