Phoenix Contact’s the TMC 8 series UL 489 Listed circuit breakers has 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 safely open circuits during overload and short-circuit events, which prevents the wiring from causing fires. The TMC 8 series breakers are available in 1-, 2-, and 3-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.
