MM-Serie-Ss eries
CIRCUIT BREAKER
The M-Series is a low cost, miniature, hydraulic-magnetic circuit breaker which features a compact, space saving
design, front panel snap-in mounting and a vertically mounted parallel pole configuration. It features various
styling options to maximize your design flexibility. Choices include rocker, illuminated rocker, paddle and
baton style handle actuators, push-to-reset and push-pull pushbutton actuators, as well as Visi-Rocker two color
actuators. Our exclusive Rockerguard bezel helps prevent inadvertent actuation and a wiping contact mechanism
assures long-term reliability.
The M-Series circuit breakers are available with 1, 2 or parallel poles, 0.02 to 50 amp ratings, and 125 and
250VAC or 80VDC versions. With over 16 different time delays, 5 terminal styles, a variety of panel hardware,
various colors, and legend imprinting, it assures suitability for most any application design.
