The TMC 8 series of UL 489-listed circuit breakers offers a trip-free design that increases safety against closing during an overcurrent event, while the snap-action mechanism eliminates contact welding and reduces contact wear. These circuit breakers provide required fundamental branch circuit protection. They open circuits safely during overload and short-circuit events, which prevents the wiring from causing fires. The breakers are available in one-, two- and three-pole options, with B-, C- and D-trip curves, to accommodate a variety of applications. The breakers also include visual trip status indication and several accessories, including auxiliary contact, alarm contact, shunt trip and cuttable busbars.
