Switches & Panels

Blue Sea Systems' circuit breaker features compact design which enables high density circuit protection configurations. Ignition protected - safe for installation aboard gasoline powered boats. Branch circuit breakers (can also be used for 24-hour circuit protection).

The Blue Sea Systems 7903200-BSS Spare Locking Key is designed for use with the M-Series Battery Switch. The key is an exact replacement and installs without tools. The switch is designed for single-circuit ON/OFF applications.

Blue Sea Systems' terminal blocks feature a closed back design which completely insulates power from the mounting surface. Each screw pair is one isolated circuit. Built with nylon base and nickel-plated brass bus and #6 and #8 screws.

ATO/ATC-Style Circuit Breakers are designed to be used as manually resettable circuit breakers instead of an ATC or ACT fuse. Manual push-button reset complies with ABYC circuit protection requirements. Compatible with water-resistant ST-blade fuse block with cover secured. Compatible with all other ST-blade fuse...

Blue Sea Systems' terminal block jumpers allow creation of common circuits on independent connectors. Bus material is composed of nickel-plated brass for resistance to corrosion. Sold as a pack of 5.

Weather resistant Contra III Rocker Switches feature a non-corrosive plastic construction that protects against dust and prolonged spray. Supplied with neoprene mounting gasket. Removable actuators. Brass blade terminals with silver contacts. Rated: 20 Amps @ 12V DC.

Blue Sea Systems' common busbar covers are made with strong, clear polycarbonate material. Fits Blue Sea System BusBar. Specifically for use with Blue Sea System numbers 2301 and 2303.

ST glass 6 circuit fuse block with negative bus and cover features a clear insulating cover with label recesses for accept large format labels. Cover insulates all conductive parts, satisfying ABYC/USCG requirements and storing spare fuses. Tin-plated copper buses and phosphor bronze fuse clips...

Blue Sea Systems' circuit breaker features compact design which enables high density circuit protection configurations. Ignition protected - safe for installation aboard gasoline powered boats. Branch circuit breakers (can also be used for 24-hour circuit protection).

Blue Sea Systems' ATC easy ID fuses are illuminated ATC blade fuses which use Light Emitting Diodes to show which fuse has been blown. Replaces non-illuminating ATO or ATC fuses. Designed for use with marine applications.

Blue Sea Systems ATO / ATC Fuses are fast-acting type fuses ideal for electronic devices and are a standard circuit protection device for automobiles and trucks. Each fuse features tin-plated connector blades for corrosion resistance. Sold in packages of two fuses.

Drop in replacement for 185-Series circuit breakers. Visible reset lever shows open condition. Ignition protected - safe for installation aboard gasoline powered boats.

Circuit breaker, push button is resettable. Replacement for popular panel mounted breakers. Mounts in 3/8 inch hole. White buttons for DC and black buttons for AC. Use MP39210 for weatherproof boot nut. Amperage rating of 10.

Blue Sea Systems' stud cablecap insulators insulate stud type connectors on alternators, starters, windlasses and other high amperage devices. Built for use in marine environments. Comes in a pack of two.

Blue Sea Systems' circuit breaker combines switching and circuit protection into a single device. Meets ABYC standards. "Trip Free" design cannot be held "ON" during fault current condition.

Automatically combines batteries during charging, isolates batteries when discharging and when starting engines. Protects sensitive electronics by temporary isolation of house loads from engine circuit during engine cranking. 12/24 volt auto ranging voltage input.

Requires the use of Terminal Fuse Blocks PN 5191 or PN 2151do not mount the fuse directly to the battery terminal. Interrupt rating satisfies ABYC requirements for DC Main circuit protection on large battery banks. Made from quality parts.

Blue Sea Systems' DC labels are reinforced with weatherproof material. Used on all Contura waterproof circuit breaker panels. Used on Contura waterproof fuse panels. Used on ST blade fuse blocks.

Compact, high-amp fuseappropriate for DC Main, inverter, windlass, and bow thruster circuit protection. Provides high current protection in tight space constraints. Ignition protected when used with Blue Sea Systems' MRBF Terminal Fuse.

15A push button backlit switch is blue when OFF and red when ON. Five ICON labels included. Accessory, lights, anchor light, running light and bilge pump are all included. Additional 50 ICON label kit sold separately.
