The Blue Sea 7187 100 Amp Circuit Breaker Surface Mount 285 Series is a thermal circuit breaker designed for critical electrical protection in marine, RV, and off-grid power systems. This 100-amp rated breaker provides reliable overload and short-circuit protection in applications where electrical safety cannot be compromised. The visible reset lever clearly indicates breaker status, allowing operators to quickly assess whether the system is armed or has tripped.
As a drop-in replacement for older 185-series circuit breakers, the Blue Sea 7187 offers a direct upgrade path for systems requiring modernization. The 285 Series features "Trip Free" technology—a critical safety mechanism that prevents the breaker from being manually held in the closed position after it has tripped, ensuring the device functions as designed even under operator pressure. The surface mount configuration enables flexible installation in panel layouts where space or existing infrastructure constraints exist. At 0.35 lbs and compact dimensions (5 x 3 x 7 inches), the breaker integrates seamlessly into existing electrical enclosures without requiring extensive reconfiguration.
This breaker is essential for operators managing electrical systems in vessels, mobile command centers, emergency response vehicles, and remote installations where power distribution integrity is non-negotiable. The 100-amp capacity addresses mid-range loads typical in expeditionary setups, specialized vehicles, and backup power configurations. Blue Sea Systems' reputation for precision marine electrical components makes this breaker a trusted choice for professionals who depend on reliable circuit protection in demanding environments.
The thermal design responds to sustained overcurrent conditions by automatically disconnecting the circuit, preventing equipment damage and fire risk. Compatibility with Blue Sea's broader electrical architecture simplifies system design and maintenance for integrated power management solutions.
