Blue Sea Systems 187-Series Surface Mount 135A Circuit Breaker – Manual Reset, Trip-Free Design For Marine & DC Systems

About This Product

This Blue Sea Systems 187-series circuit breaker does double duty – it's both a switch and a circuit protector in one compact unit.

Rated at 135 amps, it's designed for DC electrical systems on boats, RVs, or off-grid setups.

The surface mount design makes it easy to install on panels, bulkheads, or any flat surface.

The single lever gives you clear on/off control, and the trip-free mechanism means you can't hold it in the ON position if there's a fault – it's designed to trip even if the lever is forced, which is a critical safety feature.

It's a manual reset type, so after a trip, you need to physically flip it back to ON once you've cleared the issue – no hidden resets.

Built to withstand marine environments and high-current applications, this breaker is reliable and robust.
Perfect for main battery switches, inverter protection, or any heavy-duty DC circuit that needs both switching and overcurrent protection.
