HD 150A resettable circuit breaker

This is a robust 150-amp thermal circuit breaker designed for electrical protection in marine environments. It features a switchable reset function and is designed for surface mounting.

Its primary function is to protect high-current electrical circuits from overloads and short circuits, ensuring the safety and reliability of electrical systems aboard boats.

'HD' stands for 'Heavy Duty', indicating that this circuit breaker is designed to be particularly robust and durable, capable of withstanding the demanding conditions of marine applications.

This circuit breaker has a rated capacity of 150 amperes, making it suitable for circuits requiring protection against high currents.

This is a thermal circuit breaker, meaning it trips in response to a temperature increase caused by excessive current.

The switchable reset feature means the circuit breaker can be used as a manual switch to cut or restore power, in addition to its automatic overload protection function. It allows manual reset after tripping.

Unlike a fuse that must be replaced after each trip, this circuit breaker can be manually reset, offering convenience and long-term cost savings. It can also serve as a circuit switch for power cutoff.

Yes, it is specifically designed for demanding marine environments. Its 'Heavy Duty' (HD) design and materials ensure reliable durability and performance in harsh nautical conditions.

Yes, thanks to its switchable reset function, it can be used to manually cut power to a circuit, acting as an on/off switch or disconnect for maintenance or safety reasons.

This circuit breaker is manufactured by BEP, a brand known for its power distribution and management solutions in the marine sector.

This circuit breaker is manufactured in New Zealand.

It is designed for surface mounting, meaning it is fixed directly onto a flat surface using screws, without requiring complex cutting for flush installation.

Circuit breakers of this capacity typically use stud terminals for secure and robust connections with large-gauge cables, often sized M8 or 5/16 inch.

For optimal performance and extended lifespan, it is recommended to install the circuit breaker in a dry, well-ventilated location, protected from direct water spray and excessive heat, even though it is designed for the marine environment.

It is ideal for protecting high-current circuits such as battery charging systems, inverters, bow thrusters, windlasses or other high-power equipment on board vessels.

Yes, marine circuit breakers of this capacity are generally compatible with 12V and 24V DC systems. They are designed for direct current (DC) applications typical of boats.

No, this circuit breaker is a thermal circuit breaker designed for direct current (DC) applications, typical of boat battery and charging systems. It is not suitable for AC systems.

Yes, it is often used as the main protection for battery circuits or for high-power equipment, offering the advantage of being resettable compared to a fuse.
