The Phoenix Contact 2800859 is a thermomagnetic device circuit breaker designed for reliable circuit protection. This 1-position unit offers a precise nominal current of 2A and a rated voltage of up to 277V AC or 50V DC.
Key electrical specifications include a fast-blow fuse type, a rated surge voltage of 2.5 kV, and a rated short-circuit switching capacity of 300A at 240V AC and 600A at 50V DC. The device operates using a thermomagnetic tripping method with a trip-free mechanism.
Mechanically, the circuit breaker has a compact design with dimensions of 45mm height, 12.3mm width, and 52mm depth. It features an IP30 degree of protection for the actuation area and is designed for mounting on a base element. The operating ambient temperature range is -30°C to 60°C.
This modularly expandable device is suitable for applications requiring precise current limiting and monitoring capabilities. Its plug-in housing concept allows for easy integration and expansion within systems.
The circuit breaker is rated for 277VAC (UL 1077) and 50VDC (IEC 60934).
