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 Compact design actuators as well as non-illuminated or illuminated rocker versions with LED or neon bulbs. The exclusive Rockerguard Applications: bezel helps prevent inadvertent actuation and wiping Communication equipment contact design insures long-term reliability. The M-Series Vehicles circuit breakers are available in 1 & 2 poles or parallel poles, Marine 0.02 to 50 amps, up to 250VAC or 80VDC with choices of Generators time delays, terminals, panel hardware, actuator styles, Power supplies colors, and imprinting.
