Circuit breaker series 187 - Surface mount 40 A

Designed for protection of marine electrical circuits, the BLUE SEA series 187 circuit breaker, part number 7138-BSS, provides 40 A protection with surface mounting. This model is part of the BLUE SEA circuit breaker range, known for its reliable electrical components for marine environments. Its design allows direct installation on a bulkhead or dashboard, facilitating access and maintenance.

Marine Electrical Protection

The BLUE SEA series 187 circuit breaker is specifically suited to interrupt current overloads and short circuits in 12 V or 24 V boat systems. Unlike fuses, which require replacement after activation, this circuit breaker can be manually reset once the issue is resolved, offering greater convenience. Its 40 amp capacity makes it suitable for protecting medium-power circuits, such as navigation systems, bilge pumps, or certain onboard comfort equipment.

Integration and Functionality

BLUE SEA series 187 circuit breakers are alternatives to more complex models or simple fuses. They differ from push-button circuit breakers by their reset lever, which clearly indicates the circuit state (open or closed). For installations where space is limited or where easily accessible protection is required, this surface-mount circuit breaker is a practical option, comparable in function but different in format from flush-mount panel circuit breakers or combined battery switches that offer additional power management functions. It complements an electrical installation by providing dedicated, resettable protection for essential equipment.
