Circuit breaker series 285 - Surface mount 40 A

The BLUE SEA 285 series circuit breaker is an electrical protection device designed specifically for marine circuits. This model, 7182-BSS, has a 40-amp capacity and is intended for surface-mount installation. It protects equipment and cables from damage caused by overcurrent.

This circuit breaker has a rated current of 40 amperes (40 A). This means it is designed to operate normally up to this current and will trip if this value is significantly exceeded to protect the circuit.

This circuit breaker protects marine electrical circuits from overcurrent and short circuits. In case of failure or overload, it automatically interrupts the current to prevent damage to connected equipment and cables, ensuring the safety of the installation.

The main difference is that this circuit breaker is resettable. Unlike a fuse, which must be replaced after tripping, the 285 series circuit breaker can be manually reset once the cause of the overcurrent has been resolved, providing convenience and reducing the need for spare parts.

Yes, the BLUE SEA 285 series circuit breaker is specifically designed for the marine environment. It is made with corrosion-resistant materials and features a robust design to withstand the harsh conditions encountered onboard boats, including moisture and vibrations.

This circuit breaker provides thermal protection against overcurrents. It is designed to trip when the current exceeds its rated value for a given period, thereby protecting cables and equipment from overheating and damage.

This circuit breaker features a manual reset mechanism. After a trip caused by an overload, you must identify and correct the cause of the overload. Then, you can reset the breaker by pressing the lever or reset button, depending on the specific model.

The Blue Sea 285 series circuit breaker is typically designed for direct current (DC) systems and can support a maximum voltage of 48V DC. It is compatible with 12V, 24V and 48V DC systems commonly used in marine applications.

The interrupting rating (AIC - Amperes Interrupting Capacity) of this circuit breaker is 3000 amperes at 48V DC. This indicates the maximum current the breaker can safely interrupt during a short-circuit without being damaged.

Yes, the Blue Sea 285 series surface-mount circuit breaker is rated IP67. This certification means it is dust-tight and can withstand temporary immersion in water (up to 1 meter for 30 minutes), making it suitable for exposed marine environments.

This circuit breaker is designed for surface mounting. This means it is fixed directly to a wall or panel using screws, without requiring a cutout for flush mounting. Its design allows for easy and quick installation.

The circuit breaker is mounted on a surface using screws. It has mounting holes integrated into its housing. Simply position the circuit breaker at the desired location, mark the drilling points, then secure it firmly to the surface.

Basic tools are generally required for installing this circuit breaker, such as screwdrivers, wire strippers, crimping pliers for cable terminals, and a socket or open-end wrench to tighten the connection stud nuts. Ensure you use the appropriate tools to guarantee secure connections.

Yes, the Blue Sea 285 series circuit breaker can be mounted in any orientation (vertical, horizontal, or inverted) without affecting its performance or protective capability. This provides great flexibility for integration into various electrical panel configurations on board.

Yes, this circuit breaker is fully compatible with marine electrical systems operating at 12V DC and 24V DC. Its maximum voltage rating of 48V DC makes it suitable for a wide range of low-voltage applications aboard boats.

With a 40 A rating, this circuit breaker is suitable for protecting medium-power circuits. It can be used for equipment such as bilge pumps, small windlasses, navigation systems, DC-DC converters, or other significant onboard loads requiring overcurrent protection.

Yes, depending on the total consumption of your boat’s main circuit, a 40 A circuit breaker can be used to protect the main circuit, particularly on smaller installations. For larger boats with higher power demands, circuit breakers with higher current ratings may be required.

No, the Blue Sea 285 series circuit breaker is specifically designed and certified for direct current (DC) systems up to 48V DC. It must not be used for alternating current (AC) electrical installations, as it would not provide adequate protection and could be hazardous.

Although designed for the marine environment, this circuit breaker can technically be used in land or automotive applications requiring 40 A DC circuit protection, provided that voltage and current specifications match the system requirements. Its robustness and moisture resistance are also advantages in these contexts.
