Blue Sea Systems 187 Series Panel Mount Circuit Breaker

The Blue Sea Systems 187 Series Panel Mount Circuit Breaker is a thermal DC circuit breaker. It gives you heavy-duty circuit protection and a manual on/off switch in one device. It suits marine electrical systems, battery circuits, and other 12V to 48V DC systems where you want to switch and protect a circuit with one part.

Key Features:

• Combines switching and circuit protection in a single device
• Single-lever operation. The large lever shows trip status by its vertical or horizontal position
• Trip-free design, so the breaker cannot be held ON during a fault current condition
• Waterproof construction, rated IP66
• Ignition protected under SAE J1171, so it is safe to install aboard gasoline-powered boats
• Thermally responsive bi-metal blade. Type III: switchable, manual reset, trip free
• Robust 5/16"-18 terminal studs give high-torque connections. The large clearance around the studs accepts heavy-gauge wire lugs
• Recessed mounting holes give a clean look. The round case installs in a standard hole-saw cutout
• Thermoset polyester case. Operating temperature range of -40°C to 85°C
• Maximum voltage of 48V DC. CE marked

Blue Sea Systems builds the 187 Series for harsh marine environments. It is a dependable, easy-to-read way to protect and switch DC circuits on boats, RVs, and other vehicles.
