Circuit breaker series 187 - Surface mount 60 A

Its primary role is to protect marine DC electrical circuits from overloads and short circuits. It automatically disconnects the circuit in case of excessive current to prevent damage to equipment and cables.

This circuit breaker has a rating of 60 amperes (60 A). This means it is designed to protect circuits where the nominal current does not exceed this value.

The BLUE SEA 187 series circuit breaker is specifically designed for protecting direct current (DC) circuits in marine applications. It is not intended for alternating current (AC) systems.

This circuit breaker is designed for surface mounting. This means it is fixed directly to a panel, bulkhead, or any other flat surface without requiring a cutout for flush mounting.

Mounting screws are generally not included with the BLUE SEA 187 series circuit breaker. It is recommended to use appropriate fasteners for the marine environment, corrosion-resistant.

Yes, the BLUE SEA 187 series circuit breaker is ignition-protected to SAE J1171 standards, making it safe for installation in engine compartments of boats equipped with gasoline engines.

This circuit breaker is designed to operate efficiently across a wide temperature range, from -40°C to +85°C.

This circuit breaker has manual reset. After a trip due to overload, you must identify and correct the cause of the overload, then manually press the lever or reset button to restore the circuit. It is of the "trip-free" type, meaning it cannot be manually held closed if the overload condition persists.

The 60 A circuit breaker is often recommended to protect high-load devices such as windlasses, bow thrusters, high-flow bilge pumps, small to medium-sized inverters, or as the main protection for secondary DC distribution circuits.

For a small boat with moderate electrical needs, a 60 A circuit breaker can serve as the main protection. However, it is crucial to calculate the total maximum load of all connected equipment to ensure that 60 A is a sufficient and appropriate rating for the main protection of the system. For more complex systems or higher loads, a higher rating may be required.

While exact dimensions may vary slightly, surface-mount circuit breakers in the 187 series typically have a compact footprint. It is recommended to consult the detailed technical drawing (often available in the product images or manufacturer documentation) to obtain precise dimensions for installation planning.

Yes, like most quality products from the Blue Sea Systems brand, this circuit breaker is covered by the manufacturer's warranty. The specific warranty details are provided by Blue Sea Systems and typically cover material and manufacturing defects.
