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
Features:
paddle and baton style handle actuators, push-to-reset
Parallel pole configuration well suited for one rack unit
and push-pull pushbutton actuators, Visi-Rocker two color
