Wyłącznik serii 285 – montaż powierzchniowy 120 A

The primary function of this circuit breaker is to protect high-current marine electrical circuits. It detects overloads or short circuits and automatically cuts off the power supply to prevent equipment damage and onboard fire hazards.

This circuit breaker is designed for a rated current of 120 amperes (120 A).

Yes, this circuit breaker is specifically designed for harsh marine environments. It is resistant to vibration and corrosion, ensuring essential reliability for electrical installations on board vessels.

It is suitable for protecting equipment requiring a 120-ampere capacity, such as windlasses, power inverters, or main circuits on vessels.

Marine circuit breakers like the Blue Sea 285 series are specifically designed to withstand the demanding conditions of the marine environment, including humidity, salt corrosion, and vibrations. Unlike domestic circuit breakers, they are built with materials and specifications that ensure reliability and safety at sea.

Yes, Blue Sea 285 series circuit breakers are manual reset. After tripping due to overload or short circuit, they must be reset manually to restore power.

The exact dimensions of this circuit breaker are detailed in the product's technical drawing (image 02). It is recommended to consult this document for precise measurements required for installation.

Yes, Blue Sea’s 285-series circuit breakers are generally designed to be ignition-protected, making them safe for use in gasoline engine compartments on boats.

Blue Sea's 285 series circuit breakers are generally designed for direct current (DC) systems and can support up to 48V DC.

The interrupting rating (AIC) of this circuit breaker is typically 3000 amperes at 48V DC, indicating its ability to interrupt a high short-circuit current without sustaining damage.

This circuit breaker is designed for surface mounting. This means it can be directly fixed to existing bulkheads or panels without requiring recessing.

Yes, its surface-mount design simplifies installation, whether for new installations or upgrades, providing flexibility in situations where space behind the panel is limited.

Installation typically requires basic tools for marine electrical wiring, such as screwdrivers, a crimping tool for terminals, and fasteners suitable for the mounting surface. It is recommended to follow the manufacturer's specific instructions for correct installation.

The circuit breaker is equipped with stud-type terminals for input and output connections. It is essential to ensure that the cables used are of the appropriate cross-section for the 120 A rating and that the connections are properly tightened to guarantee safety and efficiency.

Yes, as it is generally ignition-protected, this circuit breaker can be safely installed in the engine compartments of gasoline-powered boats, reducing the risk of explosions caused by sparks.

Yes, this circuit breaker is compatible with 12V and 24V DC systems, as well as voltages up to 48V DC, making it versatile for most marine electrical installations.

Yes, this Blue Sea Systems circuit breaker is a standard electrical protection component and can be used to protect equipment from various brands (such as Victron Energy or Mastervolt) as long as current and voltage specifications are met.

Yes, a 120 A circuit breaker like this one can replace a 120 A fuse for circuit protection. The advantage of a circuit breaker is that it can be manually reset after tripping, unlike a fuse which must be replaced.

Yes, as long as the system voltage (e.g., 12V, 24V, 48V) and the maximum circuit current (120A) are respected, this circuit breaker can be used to protect circuits powered by lithium batteries. It is crucial to ensure the circuit breaker is correctly sized for the battery's maximum discharge current and connected equipment.

Yes, this Blue Sea Systems circuit breaker is covered by the manufacturer's standard warranty. For specific details regarding the duration and warranty conditions, please refer to the information provided by the manufacturer or the retailer.
