Disjunctor serie 187 - Montaj la suprafață 80 A

The Blue Sea 187 series circuit breaker is a thermal protection device designed for marine electrical systems. It is specifically rated for 80 A and is surface-mounted, making installation on electrical panels or bulkheads straightforward.

The primary function of this circuit breaker is to protect electrical systems and wiring from overcurrents and short circuits. In case of overload, it automatically cuts off the circuit to prevent equipment damage and fire hazards.

This circuit breaker is designed to operate with a maximum voltage of 48 V DC, making it compatible with a wide range of marine electrical installations, including 12 V, 24 V and 36 V systems.

Yes, this circuit breaker has an IP66 ingress protection rating. This means it is protected against powerful water jets and temporary immersion, making it ideal for exposed marine environments.

Yes, the Blue Sea 187 series circuit breaker is a resettable thermal circuit breaker. After tripping due to an overcurrent, it can be manually reset once the cause of the overload has been identified and corrected, eliminating the need to replace fuses.

Yes, Blue Sea’s 187 series circuit breakers are generally designed to be ignition-protected, making them safe for use in boat engine compartments where flammable vapors may be present.

This circuit breaker uses 5/16"-18 stainless steel stud terminals, ensuring a robust and corrosion-resistant electrical connection, essential in a marine environment.

Compared to a fuse, this circuit breaker offers several advantages:

Resettable: It can be manually reset after tripping, avoiding the need to replace parts. Enhanced protection: It provides precise thermal protection against overcurrents. Durability: Its robust design and IP66 rating make it more resistant to marine environments.

This circuit breaker is designed to operate efficiently across a wide temperature range, typically from -40°C to +85°C, ensuring reliability in various marine weather conditions.

Yes, Blue Sea Systems products, including the 187 series, are generally designed to meet ABYC (American Boat and Yacht Council) and SAE (Society of Automotive Engineers) standards for marine electrical equipment, ensuring their safety and performance.

The circuit breaker is made with robust materials resistant to corrosion, suitable for the marine environment. It typically features a thermoplastic housing and stainless steel studs.

This circuit breaker is designed for surface mounting. It is typically secured with two screws (not included) on a flat surface, such as an electrical panel or a bulkhead. The wiring is then connected to the studs.

To mount this circuit breaker on a surface, you will need two mounting screws (usually size #10), tools for tightening cable connections to the studs (wrenches or sockets), and appropriately sized electrical cables rated for 80 A.

This circuit breaker should be installed in a location that is easily accessible for manual reset but protected from direct physical impacts. With its IP66 rating and ignition protection, it can be installed in damp compartments or even in the engine room.

During wiring installation, ensure you use cables of adequate cross-section to handle 80 A to prevent overheating. Connections to studs must be clean, tight, and protected against corrosion. It is also essential to disconnect the power supply before any intervention.

Yes, this 80 A circuit breaker is fully suitable for 12 V marine electrical systems. Its maximum voltage of 48 V DC allows it to operate without issues in lower-voltage configurations.

Yes, given that the maximum voltage of this circuit breaker is 48 V DC, it is fully compatible and can be safely used with 24 V and 36 V marine electrical systems.

This 80 A circuit breaker is ideal for protecting intermediate to high-power circuits. It is commonly used for equipment such as windlasses, bow thrusters, medium-sized inverters, high-flow bilge pumps, or main distribution circuits on boats.

Yes, as a Blue Sea Systems product, this circuit breaker is designed to integrate seamlessly with other brand components such as busbars, distribution panels, or battery switches, to create a consistent and reliable marine electrical system.
