The Phoenix Contact 2800866 is a single-pole thermomagnetic device circuit breaker designed for reliable circuit protection. It offers a rated current of 12A and a rated voltage of 277V AC (UL) or 240V AC (IEC), with DC voltage ratings up to 50V.
This breaker utilizes a thermomagnetic tripping method with an F1 (fast-blow) characteristic, ensuring quick response to overcurrents. It includes a 1 PDT contact for signaling purposes and a trip-free mechanism for enhanced safety. The compact design and plug-in housing concept allow for modular expansion and integration with CLIPLINE complete accessories.
Installation is on a base element, and the device has dimensions of 45mm height, 12.3mm width, and 52mm depth. It operates within an ambient temperature range of -30°C to 60°C and has an IP30 degree of protection for the actuation area. The breaker is constructed with an insulating material group II and meets UL 94 V0 flammability standards.
240 V AC (IEC 60934), 277 V AC (UL 1077, UL 508 with plug-in base), and 50 V DC (IEC/UL).
