Circuit breaker series 285 - Panel mount 80 A

The BLUE SEA 285 series circuit breaker is an electrical protection device designed specifically for marine applications. This 80-amp model is intended to protect direct current (DC) circuits from overloads and short circuits, ensuring the safety of your equipment and electrical installation aboard.

The primary function of this circuit breaker is to protect marine electrical circuits by automatically interrupting the current flow in case of overload or short circuit. This prevents equipment damage, fire hazards, and ensures overall electrical system safety.

This BLUE SEA 285 series circuit breaker has a rated current of 80 amperes (A). It is designed for circuits requiring protection against high currents.

The main advantage of a circuit breaker is that it is resettable. After an overload or short circuit, you only need to reset the circuit breaker manually to restore power, unlike a fuse which must be replaced after melting. This makes troubleshooting easier and reduces the need for spare parts.

This circuit breaker is specifically designed for panel mounting. It integrates cleanly and accessibly into electrical panels or control consoles on vessels.

This circuit breaker is ideal for protecting high-current circuits such as those of inverters, bow thrusters, windlasses, or as main protection for major distribution circuits on a boat.

After tripping due to an overload or short circuit, the circuit breaker opens automatically. To reset it, simply press the reset button or lever (depending on the exact model in the 285 series) to return it to the "ON" position once the cause of the issue has been identified and corrected.

Yes, in addition to its automatic protection function, the Series 285 circuit breaker can also be used as a manual switch to cut or restore power to a specific circuit at will.

Yes, Blue Sea Systems 285-series circuit breakers are specifically designed for marine environments. They are built with robust, corrosion-resistant materials to ensure reliable performance in damp and saline conditions.

For panel installation, a precise cut must be made in the panel to accommodate the circuit breaker body. The exact cutout size and mounting dimensions are typically provided in the product's technical documentation.

This BLUE SEA 285 series circuit breaker is designed for direct current (DC) systems typically found on boats.

Yes, Blue Sea’s 285-series circuit breakers are generally compatible with 12 V, 24 V, and 32 V DC marine electrical systems, covering most installations aboard vessels.

For an 80 A circuit breaker, the recommended cable cross-section depends on cable length and permissible voltage drop. It is essential to consult ABYC standards or a qualified marine electrician to select the appropriate cable cross-section to prevent overheating and ensure safety.

The 285 series circuit breakers are designed to be installed on the positive circuit (+). Although they are not strictly polarized (they work in both directions), it is recommended to install them on the positive wire for standardized circuit protection.

The circuit breaker must be installed as close as possible to the power source (battery or distribution bus) and before the equipment it is intended to protect. This ensures maximum protection against overcurrent throughout the circuit.

BLUE SEA SYSTEMS products, including the 285 series, are generally designed to meet or exceed the standards of recognized marine bodies such as ABYC (American Boat and Yacht Council) and the U.S. Coast Guard (USCG), ensuring their reliability and safety for marine applications.

Yes, Blue Sea’s 285-series circuit breakers are designed to withstand spray and the humid environments typical of boats. Their rugged construction and sealing gaskets provide good protection against water ingress.

For installation, you will generally need a drill with a hole saw or a file for cutting the panel, a screwdriver for fasteners, and a crimping tool for wiring terminals.

No, this circuit breaker is designed to protect against overcurrents (overload and short circuit). It does not directly protect against overvoltages (excessive voltages), for which other protective devices (such as surge protectors) would be required.

Although designed for the marine environment, this circuit breaker can technically be used in other DC (direct current) applications requiring 80 A protection and panel mounting, provided that the technical specifications (voltage, current, environment) are met.
