UL 1077 Circuit Breakers: Easy-to-Maintain Overcurrent Protection with a Wide Range of Accessories

Middletown, Pa. – Phoenix Contact introduces the TMC 7 series of circuit breakers, designed for UL 1077 supplementary overcurrent protection. The TMC 7 series uses snap-action technology that eliminates the need for contact welding and reduces wear and tear on the internal contacts of the device. This increases product longevity.

The trip-free design eliminates closing the circuit during an overcurrent event, ensuring safety. The device also increases reliability by isolating problems in the system while allowing for continued operation. The series complements the popular TMC 8 series of UL 489 circuit breakers.

Like the TMC 8 series, the TMC 7 series is available in 1-, 2-, and 3-pole options, with B-, C-, and D-trip curves to accommodate a variety of applications and load types. They include visual trip status indication. The snap-on accessories, including auxiliary contact, alarm contact, shunt trip, and cuttable bus bars, are the same as those used in the TMC 8 series, allowing for a reduction in inventory, costs, and installation time.
