The Phoenix Contact 2800842 is a thermomagnetic device circuit breaker from the CB TM1 series, featuring SFB (Selective Fast Blow) tripping characteristic. It is rated for 8 A continuous current at 277 V AC (UL 1077) and 50 V DC, with a short-circuit breaking capacity of 300 A at 240 V AC. The 1-pole design uses a slide actuator and mounts on a base element (holder mount).
Key electrical specifications include a rated surge voltage of 2.5 kV, insulation resistance of 100 MΩ at 500 V DC, and an auxiliary circuit rating of 277 V AC / 0.5 A (low-induction). The operating temperature range is -30°C to 60°C, with storage from -40°C to 80°C. The housing is gray with IP30 protection on the actuation area and V-0 flammability class per UL 94.
This circuit breaker is designed for modular expansion and remote monitoring. The SFB characteristic enables reliable overcurrent protection for long cable paths with high inrush currents. The compact dimensions (45 mm height, 12.3 mm width, 52 mm depth) allow efficient panel layout. A backup fuse rated 32 A is required.
