Enerdrive ST CLB Circuit Breaker Block 6 or 12 Independent Circuits with Cove
The Blue Sea Systems ST CLB Circuit Breaker Block provides convenient circuit protection using compact, resettable CLB circuit breakers that snap into place, making installation as simple as installing a fuse.
Available in 6-circuit and 12-circuit configurations, both models feature independent circuit sources, tin-plated copper bus bars and screw terminals for reliable electrical connections.
The clear insulating cover features square-format circuit label recesses and meets ABYC/USCG insulation requirements. Its easy-open clip-on design provides convenient access, while wire access breakouts allow wiring from two directions.
The blocks accept ring terminals, and optional push-button waterproof boots or dress nuts can be installed over the cover.
Choose the 6-circuit model for smaller installations or the 12-circuit model for systems requiring additional independently sourced circuits.
