The Phoenix Contact 2800855 is a thermomagnetic device circuit breaker designed for reliable protection of 230/240 V AC power supply systems. It features a compact design with precise nominal current levels and a tripping characteristic of M1 (medium-blow).
Key technical specifications include a rated current of 12A (IEC 60934) and a rated voltage of 277V AC (UL 1077) or 240V AC (IEC 60934). The device operates within an ambient temperature range of -30°C to 60°C and has a degree of protection of IP30 at the actuation area.
This circuit breaker is designed for mounting on a base element and offers modular expansion possibilities due to its uniform, plug-in housing concept. It also features a sophisticated remote signaling concept for monitoring from any location. The supply and remote signaling can be bridged using CLIPLINE complete accessories.
With a rated surge voltage of 2.5 kV and a rated short-circuit switching capacity of 300A at 240V AC, the 2800855 provides robust protection. Its dimensions are 45mm in height, 12.3mm in width, and 52mm in depth.
The rated current is 12A according to IEC 60934.
The rated voltage is 277 V AC according to UL 1077 and UL 508.
The ambient temperature for operation is -30 °C to 60 °C.
The degree of protection is IP30.
It uses a thermomagnetic tripping method with a trip-free mechanism.
