June 30, 2016 – Phoenix Contact introduced a line of UL 489 Listed circuit breakers – the TMC 8 series. A trip-free design increases safety against closing during an overcurrent event, while the snap-action mechanism eliminates contact welding and reduces contact wear.
These UL 489 Listed circuit breakers provide required fundamental branch circuit protection. They 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.
Designed to handle an interrupt capacity of 10 kA IC at up to 277/480 V AC and 125 V DC, the 17-mm DIN rail-mounted breakers are ideal for a wide range of applications. In addition to the UL Listing, the TMC 8 breakers also have international approvals for global use.
