The Phoenix Contact 1019931 is a thermal magnetic miniature circuit breaker with a 2A current rating and a 277V voltage rating. This 2-pole breaker is designed for branch overload and short-circuit protection. It features a lever actuator and mounts directly onto a 35 mm NS35 DIN rail, making installation straightforward in control panels and electrical enclosures.
The TMC 7... and TMC 8... series, to which this part likely belongs, offer various trip curve options (B, C, D) and are suitable for protecting cables, motors, generators, transformers, and electronic equipment. The TMC 8... series boasts an interrupt capacity of 10 kAIC at up to 277/480 V AC and 125 V DC, while the TMC 7... series offers ratings from 5 kAIC to 7.5 kAIC. This specific model is 17.6 mm wide per pole.
This circuit breaker is suitable for a wide range of industrial process control systems, telecommunications equipment, and power supplies. Its trip-free, snap-action mechanism ensures reliable protection by preventing manual override during overload situations. Accessories such as auxiliary contacts, shunt trips, and busbars are available for expanded functionality.
