Description

The Bussmann BK/UCB-30 is an automotive circuit breaker designed for 12V DC systems. It features an automatic reset mechanism, meaning it can restore power after a fault condition without manual intervention, unlike a traditional fuse. This breaker has a 30A current rating and a single-pole configuration, suitable for direct load switching. Its holder-mounted design simplifies assembly in compact electronic modules.
