Blue Sea Systems Series DC Circuit Breaker Surface Mount

Blue Sea Systems surface mount DC circuit breakers combine circuit protection and manual switching in one device. They are built for marine electrical systems, and the thermal design suits boats, RVs and other DC applications that need a resettable alternative to a fuse. Use one as a battery circuit breaker, main DC breaker or branch circuit protector.

Key Features:

• Protection and switching in one: a single device protects the circuit and lets you switch it on and off.
• Trip-free design: the breaker cannot be held closed during a fault condition.
• Clear lever indication: a visible reset lever shows whether the breaker is on, off or tripped.
• Ignition protected: meets SAE J1171 external ignition protection requirements, so it is suitable for installation aboard gasoline-powered boats.
• Weather and water resistant: engineered for harsh marine environments.
• Thermal bi-metal operation: a thermally responsive bi-metal blade provides reliable, manually resettable overcurrent protection.
• Surface mount: the breaker screws to a bulkhead or panel, with wire connections at the front.
• Heavy-duty terminal studs: studs give secure, high-torque connections for ring terminals and cable lugs.
