The Phoenix Contact 2800850 is a single-pole thermomagnetic device circuit breaker designed for protecting 230/240 V AC power supply systems. It features a medium-blow M1 tripping characteristic, suitable for applications requiring a C characteristic curve.
Key electrical specifications include a rated voltage of 240V AC (IEC 60934) and 277V AC (UL), with a rated current of 4A. The device also offers an auxiliary circuit rating of 277V AC / 0.5A and 50V DC / 1A. It has a rated surge voltage of 2.5 kV and an insulation resistance greater than 100 MΩ at 500V DC.
Mechanically, the circuit breaker has a compact design with dimensions of 45mm height, 12.3mm width, and 52mm depth. It is designed for mounting on a base element and features a slide switch actuator. The operating ambient temperature range is -30°C to 60°C, with storage and transport temperatures ranging from -40°C to 80°C.
Environmental considerations include an IP30 degree of protection for the actuation area and an inflammable class of V0 according to UL 94. The device is manufactured in Germany.
