The Blue Sea Systems Series 285 circuit breaker is an electrical circuit protection device designed specifically for marine environments. It protects equipment from overloads and short circuits by automatically cutting power when current exceeds its rated 150 A. It serves as an alternative to traditional fuses, offering manual reset.

The primary function of this circuit breaker is to protect marine electrical circuits from damage caused by overcurrents (overloads) and short circuits. In the event of a problem, it interrupts the current flow, thereby preventing risks of fire, cable degradation, and damage to connected equipment. Once the issue is resolved, it can be reset manually.

This Blue Sea Systems 285 series circuit breaker has a nominal current rating of 150 amperes (150 A). This means it is designed to protect circuits where the normal current does not exceed this value and will trip if the current exceeds it in a hazardous manner.

The main advantages of this circuit breaker compared to traditional fuses are:

Quick reset: After tripping, it can be manually reset with a simple button press, without requiring the replacement of a part.Savings: No need to carry spare fuses on board.Improved safety: It provides reliable protection against overloads and short circuits, and many models are ignition-protected for engine compartment use.

Yes, the Blue Sea Systems 285 series circuit breaker is specifically designed to withstand demanding marine environments. It is manufactured with corrosion-resistant materials and often features protection against water spray and dust (typically rated IP67), making it suitable for use aboard vessels.

This Blue Sea Systems 285 Series circuit breaker is designed to operate with electrical systems up to a maximum voltage of 48 volts DC.

Yes, the Blue Sea Systems 285 series circuit breaker is ignition-protected to SAE J1171 standards. This means it is designed not to emit sparks or excessive heat that could ignite fuel vapors or other flammable gases, making it safe for installation in engine compartments.

The interrupting rating (AIC - Ampere Interrupting Capacity) of this 285 series circuit breaker is 3000 amperes at 48 volts DC. This value indicates the maximum current it can safely interrupt in the event of a short circuit without being damaged.

This is a manually resettable circuit breaker. After tripping due to overload or short circuit, it must be reset manually by pressing its reset button.

The exact dimensions of this circuit breaker are available in the technical drawing (see the product's technical detail image). It is designed for surface mounting and its dimensions are optimized for easy integration in various marine environments.

This circuit breaker is designed for surface mounting. It must be fixed to a flat surface using screws, ensuring that the terminals are accessible for wiring. It is important to consult the installation manual for specific drilling and fastening details.

For the installation of this circuit breaker, you will generally need the following tools:

A screwdriver (suitable for mounting screws and terminals)A crimping tool for wiring terminalsA torque wrench to tighten terminal nuts to the recommended torqueA multimeter to check continuity and voltage (optional but recommended)A drill and bits if you need to create new mounting holes.

For a 150 A circuit breaker, it is essential to use high-gauge cables suitable for the circuit's maximum current and length to prevent excessive voltage drops and overheating. Consult ABYC (American Boat and Yacht Council) standards or local marine wiring regulations to determine the appropriate cable gauge (typically 1/0 AWG or larger for 150 A, depending on length and temperature).

Yes. When wiring, it is critical to respect polarity (if indicated), ensure all connections are clean and tightened to the manufacturer’s recommended torque to avoid excessive resistance and overheating. Use high-quality marine-grade cable lugs and protect connections with heat-shrink tubing if necessary. Always disconnect the power source before starting wiring.

Yes, this circuit breaker can be installed in an engine compartment because it is spark-resistant (compliant with SAE J1171). This feature ensures it will not generate sparks that could ignite fuel vapors, which is critical for safety in these areas.

Yes, this circuit breaker is compatible with 12V and 24V DC marine electrical systems. Its maximum supported voltage is 48V DC, making it suitable for common boat voltages.

This circuit breaker is ideal for marine applications requiring high-current circuit protection. It is commonly used to protect main circuits, battery chargers, power inverters, electric winches, bow thrusters, or other high-current draw onboard equipment.

Yes, this 150 A circuit breaker is perfectly suited to protect a battery charger, provided the charger's maximum output current does not exceed 150 A and the system voltage is compatible (up to 48 V DC). It provides reliable protection against overloads that may occur during the charging process.

Yes, as part of the Blue Sea Systems range, this circuit breaker is designed to integrate seamlessly with other products from the brand, such as busbars, distribution panels, and battery management systems, to build a consistent and reliable marine electrical system.

Yes, Blue Sea Systems products are known for their quality and reliability. This circuit breaker is covered by the manufacturer's standard warranty, which attests to its compliance with manufacturing standards and the absence of material or manufacturing defects.
