Blue Sea Systems 187 Series DC Circuit Breaker

The Blue Sea Systems 187 Series DC circuit breaker is a surface mount, thermal circuit breaker. It protects heavy-duty DC circuits and also works as a switch. It suits marine, RV and other DC electrical systems. The thermally responsive bi-metal design provides manual-reset protection.

Key Features:

• Combines switching and circuit protection in one device. Do not use it as a switch where high inrush currents are expected.
• Single lever operation with a large lever. The lever's vertical or horizontal position shows the trip status.
• "Trip free" design, so the breaker cannot be held on during a fault current condition.
• Waterproof construction, rated IP66.
• Ignition protected and meets SAE J1171 external ignition protection requirements. This makes it safe to install aboard gasoline-powered boats.
• 5/16" (M8) terminal studs with large clearance around them. They accept heavy-gauge wire lugs and give high-torque connections.
• Recessed mounting holes give a clean appearance.
• Rated for up to 48V DC.
• Thermoset polyester case, CE marked.

The 187 Series is built for harsh marine environments. It gives you a dependable breaker and manual switch in one compact, surface-mounted unit.
