Circuit breaker series 285 - Surface mount 70 A

This circuit breaker is designed to protect marine electrical circuits against overcurrent and short circuits. It automatically cuts power in case of a problem, preventing damage to your vessel's equipment and wiring.

Unlike a fuse that must be replaced after melting, this 285 series circuit breaker is manually resettable. After a trip due to overload or short circuit, simply operate the lever to restore power, avoiding the need to carry and replace fuses.

This BLUE SEA 285 series circuit breaker model has a rated current of 70 amperes (A). It is suitable for protecting circuits that do not exceed this value during normal operation.

Yes, the BLUE SEA 285 series circuit breaker is specifically designed for marine applications. It is made with robust materials and is typically ignition-protected (SAE J1171 compliant) and water-resistant (often IP67), making it ideal for demanding conditions aboard a vessel.

The BLUE SEA 285 series circuit breaker is designed for use with direct current (DC) systems. It typically supports voltages up to 48 Volts DC.

The BLUE SEA 285 series circuit breaker housing is typically made from robust, corrosion-resistant thermoplastic, designed to withstand harsh marine environments.

Yes, this circuit breaker is ignition-protected, meaning it is designed not to emit sparks that could ignite flammable vapors in an engine compartment. It complies with SAE J1171.

The BLUE SEA 285 series circuit breaker is designed to operate within a wide temperature range, typically from -40°C to +85°C, making it suitable for various marine climate conditions.

This circuit breaker is equipped with a manual reset lever. After an overload or short circuit, the lever trips. To restore power, simply push the lever back to the "ON" position once the issue has been identified and resolved.

This circuit breaker is a surface-mount model. This means it is designed to be directly fixed to a bulkhead, panel, or any other flat surface without requiring a recessed cutout.

For installation, you will generally need basic tools such as a screwdriver (suitable for mounting screws and terminals), a crimping tool for cable lugs, and possibly a drill for mounting holes if the surface is not pre-drilled.

While exact dimensions may vary slightly, the 285 series circuit breakers are designed to be compact. Refer to the technical diagram provided with the product or available on the product page for precise measurements of mounting holes and overall dimensions.

This circuit breaker typically uses 1/4"-20 stud terminals for connecting power and load cables. These terminals are designed to accept ring terminals.

Yes, thanks to its ignition protection (compliant with SAE J1171), this circuit breaker can be safely installed in an engine compartment or other areas where flammable vapors may be present.

This circuit breaker is compatible with marine DC electrical systems of 12V, 24V, 32V and up to 48V. It can be used to protect a variety of auxiliary equipment, house systems or main power lines on board.

No, this Blue Sea 285-series circuit breaker is designed specifically for direct current (DC) applications and is not compatible with alternating current (AC) systems of 220V or any other AC voltage.

Yes, a 70 A circuit breaker can be used to protect the circuit of a bow thruster or other high-consumption equipment, provided the thruster’s maximum current does not exceed 70 A and the system voltage is compatible (up to 48 V DC).

Yes, the BLUE SEA 285 series circuit breaker is typically rated IP67, meaning it is protected against dust and can withstand temporary immersion in water (up to 1 meter for 30 minutes). It is therefore highly resistant to water spray and humid conditions encountered in marine environments.

Yes, in addition to its function as protection against overloads and short circuits, the reset lever can also be used manually as an ON/OFF switch to cut or restore power to a specific circuit.
