The advantage of a resettable circuit breaker over a single use fuse is well known however people find circuit breakers more expensive and difficult to install. The new ST CLB Circuit Breaker Block uses the compact, snap-in-place CLB resettable circuit breaker which makes breakers as easy to install as a fuse. The ST CLB block provides flexible resettable protection for 6 to 12 circuits and is available for both common and independent DC source requirements.
