The Phoenix Contact TMC 7 and TMC 8 series includes the 1020006, a 2-pole thermal-magnetic circuit breaker with a 16A current rating and a 277V voltage rating. Designed for DIN rail mounting, this breaker features a lever actuator and is suitable for overcurrent protection of circuits and loads.
This circuit breaker complies with UL 1077, UL 489, and EN 60947-2 standards. It offers a trip-free, snap-action mechanism for reliable switching behavior. The TMC 7 and TMC 8 series are available in B-, C-, and D-trip curves, providing flexibility for different load types. This specific model is rated for systems up to 277/480 V AC and 60/125 V DC, with a Short Circuit Current Rating (SCCR) of 7.5 kA for TMC 7 and 10 kA AIC for TMC 8.
Key features include secure screw terminations, visual status indication, and dual AC/DC ratings. The snap-action mechanism helps prevent contact welding and reduces wear, while the trip-free design enhances safety during overcurrent events. Multiple accessories are available to provide added functionality and system status information.
