The Phoenix Contact TMC 8... series miniature circuit breakers (MCBs), including the 2907676 model, are designed for branch overload and short-circuit protection. These UL 489 listed devices provide an interrupt capacity of 10 kAIC at up to 277/480 V AC and 125 V DC, making them suitable for a variety of applications.
The 2907676 features a 3-pole configuration with a 3A current rating and a 480V AC voltage rating. It utilizes a thermal magnetic trip mechanism and has a lever actuator. The breaker is designed for mounting on a 35 mm NS35 rail, with each pole measuring 17.6 mm wide.
Typical applications for the TMC 8... series include the protection of cables, motors, generators, transformers, thyristors, silicon rectifiers, computers, peripheral equipment, industrial process control systems, telecommunications equipment, and power supplies. The series is UL listed for the U.S. and Canada, TÜV listed, and carries the CE mark.
