Phoenix Contact Circuit breaker with NEC Class 2 approval

The CBMC circuit breaker combines a compact design with custom configurability. The NEC Class 2-approved circuit breaker measures 36 mm wide and has four channels to protect against overload and short-circuit current in electrical applications. Each channel is electronic and adjustable from 1 to 4 A, giving the overall component a suitable protection level for NEC Class 2. When installed in a 24-Vdc application, the product limits the total output power to less than 100 W per channel. The circuit breaker also can be programmed at the factory to pre-specified current values. When ordering, users can decide whether to make the settings permanent or to allow future modifications.
