This electronic device circuit breaker from Phoenix Contact, part number 0900317, is designed for reliable circuit protection in demanding applications. It operates at a nominal voltage of 24V DC, with a permissible range of 18V DC to 32V DC, and features a nominal current rating of 3A.
The breaker utilizes a solid-state design for efficient and precise overcurrent protection, indicated by an active current limitation. It connects via screw terminals, offering a secure and robust connection method. The device has a compact width of 12.5 mm, making it suitable for space-constrained panel designs. Installation instructions note that in rows without convection cooling, the nominal device current should be limited to 80% due to thermal effects during continuous operation.
Key technical specifications include a rated surge voltage of 0.5 kV and a pollution degree of 2. The insulating material is PA66/6 with an inflammability class of V0 according to UL 94. The operating ambient temperature range is from 0°C to 50°C without condensation. The device also includes a closed-circuit current range of typically 25 mA ±5 mA when switched on.
Mounting is designed for base elements, and the unit has a single pole configuration. The device is black in color and meets Surge Voltage Category II and Insulating Material Group I standards. It is suitable for applications requiring a reliable and compact circuit protection solution.
