The Phoenix Contact 2800844 is a single-pole thermomagnetic device circuit breaker designed for reliable overcurrent protection. It features a compact design with precise nominal current levels and a uniform, plug-in housing concept for modular expansion.
Key electrical specifications include a rated current of 12A (IEC 60934) and a rated voltage of 277V AC (UL 1077) or 240V AC (IEC 60934). It also supports 50V DC operation. The breaker utilizes a thermomagnetic tripping method with an SFB trigger characteristic, providing maximum overcurrent protection across long cable paths. It includes a trip-free mechanism and requires a 48A backup fuse.
Mechanical dimensions are 45mm in height, 12.3mm in width, and 52mm in depth. The device is designed for mounting on a base element and has a gray color. It operates within an ambient temperature range of -30°C to 60°C.
This circuit breaker is suitable for applications requiring robust protection and monitoring capabilities, with a sophisticated remote signaling concept. Its modular design and plug-in housing facilitate integration into various systems.
The circuit breaker is rated for 240V AC (IEC 60934) and 277V AC (UL 1077 / UL 508) at AC, and 50V DC (IEC and UL).
The operating temperature range is -30°C to 60°C.
It has an SFB tripping characteristic (thermomagnetic).
Yes, it includes a 1 PDT auxiliary contact rated at 277V AC / 0.5A (or 1A for 2000 cycles) and 50V DC / 1A.
The short-circuit switching capacity is 300A at 240V AC and 600A at 50V DC.
Module dimensions: 45mm height, 12.3mm width, 52mm depth. Complete module with base: 90mm height, 12.3mm width, 77.3mm depth.
