The Phoenix Contact 2800849 is a single-pole, thermomagnetic device circuit breaker designed for reliable protection of electrical circuits. It features a precise 3A nominal current rating and a tripping characteristic curve of M1, which is suitable for protecting 230/240 V AC power supply systems.
This circuit breaker operates at a rated voltage of up to 277V AC and 50V DC, with a rated insulation voltage of 277V AC. It has a rated surge voltage of 2.5 kV and an insulation resistance greater than 100 MΩ at 500V DC. The device utilizes a thermomagnetic tripping method with a trip-free mechanism.
Designed for modularity, the 2800849 features a plug-in housing concept compatible with CLIPLINE complete accessories for easy integration and expansion. It has a compact design with dimensions of 45mm height, 12.3mm width, and 52mm depth. The actuation area offers an IP30 degree of protection. The operating ambient temperature range is -30°C to 60°C, with storage and transport temperatures ranging from -40°C to 80°C. The inflammable class is V0 according to UL 94.
It is rated for 240 V AC (IEC 60934), 277 V AC (UL 1077), and 50 V DC (IEC 60934 and UL 1077).
