Circuit breaker series 285 - Surface mount 70 A

This circuit breaker is designed to protect marine electrical circuits from overcurrent and short circuits. It automatically cuts off power in case of a fault, 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 flip the lever to restore power, avoiding the need to carry and replace fuses.

This BLUE SEA 285 series circuit breaker model has a nominal current rating 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 built with robust materials and is typically ignition-protected (SAE J1171 compliant) and water-resistant (often IP67 rated), making it ideal for harsh conditions aboard a vessel.

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

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

Yes, this circuit breaker is spark-proof, 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 fixed directly onto a bulkhead, panel, or any other flat surface without requiring a recessed cutout.

For installation, you will typically 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 drawing provided with the product or available on the product page for precise mounting hole and overall dimensions.

This circuit breaker typically uses 1/4"-20 stud terminals for connecting power and charging 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 12 V, 24 V, 32 V and up to 48 V DC marine electrical systems. It can be used to protect a variety of auxiliary equipment, service systems or main power lines aboard.

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 dust-tight and can withstand temporary immersion in water (up to 1 meter for 30 minutes). It is therefore highly resistant to water splashes and humid conditions encountered in marine environments.

Yes, in addition to its function of protecting 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.
