Osigurač serija 285 - površinska ugradnja 150 A

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 main function of this circuit breaker is to protect marine electrical circuits from damage caused by overcurrents (overloads) and short circuits. In case of a fault, it interrupts the current flow, 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 rated current 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 dangerously.

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.Economy: No need to carry spare fuses on board.Improved safety: It provides reliable protection against overloads and short circuits, and many models are protected against ignition for use in engine compartments.

Yes, the Blue Sea Systems Series 285 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 Series 285 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 series 285 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 reset 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 diagram (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 installing this circuit breaker, you will generally need the following tools:

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

For a 150 A circuit breaker, it is essential to use cables with a large cross-section, suitable for the maximum current of the circuit and its length, to avoid excessive voltage drops and overheating. It is recommended to consult ABYC (American Boat and Yacht Council) standards or local marine wiring regulations to determine the appropriate cable cross-section (typically 1/0 AWG or larger for 150 A, depending on length and temperature).

Yes, when wiring, it is crucial to respect polarity (if indicated), to ensure all connections are clean and tightened to the torque recommended by the manufacturer 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 the wiring.

Yes, this circuit breaker can be installed in an engine compartment because it is spark-proof (compliant with SAE J1171 standard). 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 consumption 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 48V 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 brand products such as busbars, distribution panels, and battery management systems, to build a coherent and reliable marine electrical system.

Yes, Blue Sea Systems products are renowned 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.
