Thermalmagnetic circuit protection

UL 1077 and UL 489 overcurrent protection

The complete family of UL Listed 489 circuit breakers (TMC 8 series) and UL 1077 supplemental protectors (TMC 7 series) from Phoenix Contact are ideal for a wide array of applications, from machine building and oil and gas to water/wastewater, energy, transportation, and telecom. With multi-pole options, our breakers can satisfy a variety of needs while safely protecting your equipment and systems from overcurrent disturbances.

Trip-free design

With safety a key priority, our innovative breakers incorporate this feature to open during an overcurrent event, even when the switch is held closed.

Snap-action mechanism

Everyone wants a product with an exceptional lifespan. This design inherently creates a longer-lasting product by eliminating contact welding and reducing contact wear and pitting.

Flexibility in innovation

The TMC 7 and TMC 8 series offer 1-, 2-, and 3-pole options, as well as B-, C-, and D-trip curve versions to ensure the proper trip speed based on your application. There are also a variety of accessories to further increase your system’s functionality including an auxiliary contact, alarm contact, and shunt trip. Our breakers can also be bussed together, utilizing our cuttable UL 508 Listed busbars.
