Blue Sea 187-Series 135 Amp Circuit Breaker Panel Mount

The Blue Sea 187-Series 135 Amp Circuit Breaker Panel Mount is a dual-function electrical protection device engineered for applications where space and redundancy matter—marine vessels, mobile command centers, tactical power systems, and specialized vehicles. Combining switching capability with overcurrent protection into a single compact unit, this panel-mount breaker eliminates the need for separate components, reducing wiring complexity and failure points in mission-critical installations where reliability is non-negotiable.

Built with Blue Sea Systems' proven "Trip Free" design, the 187-Series cannot be held in the ON position during a fault condition—a critical safety feature that prevents accidental bypass of circuit protection when high amperage loads spike unexpectedly. The single-lever operation delivers clear, tactile feedback and allows operators to instantly isolate circuits without ambiguity, essential in high-stress environments where decisiveness and clarity prevent cascading electrical failures. At 135 amps rated capacity, this breaker handles substantial power draws while maintaining fast response times to short circuits and overloads, protecting downstream equipment and personnel from thermal and electrical hazards.

Law enforcement, military, and maritime professionals rely on the 187-Series for auxiliary power systems, portable generator integration, and battery management in field operations where electrical safety cannot be compromised. Installation requires standard panel-mount hardware and integrates seamlessly into existing DC electrical buses; the 0.5 lb unit occupies minimal footprint, making it ideal for space-constrained tactical vehicles and deployable command posts. Consult your electrical system schematic to verify proper breaker amperage sizing and wire gauge compatibility before installation.
