This circuit breaker serves as a critical safety device. It protects your marine electrical circuit from overloads and short circuits by automatically cutting power in case of a fault.

A double-pole circuit breaker cuts the current simultaneously on both the live and neutral wires, providing complete isolation of the faulty circuit. A single-pole model cuts only one wire, which is less secure for 230 V systems on board a boat.

This bipolar model is primarily designed and recommended for 230 V electrical systems on board vessels, ensuring maximum safety for alternating current.

Yes, absolutely. For directly connected devices such as lighting circuits or outlets, this circuit breaker can serve as a manual on/off switch for daily use.

This circuit breaker meets the strictest international safety requirements for the marine sector. It is certified CE, UL, CSA, and ABYC.

When installing on a 230 V system, you must connect both the live (phase) wire and the neutral wire to the circuit breaker so it can cut both simultaneously in case of an electrical fault.

This specific model has a capacity of 15 Amperes (15A). It is designed to protect circuits where the maximum consumption does not exceed this tolerance threshold.

Yes, although it is manufactured by Mastervolt, this circuit breaker uses a format compatible with most marine electrical panels designed for this type of toggle module.

Absolutely. For obvious safety reasons, any work on your electrical panel or installation of this circuit breaker must be done with the main power supply (shore power, generator, and inverter) completely turned off.

No. A 15A circuit breaker is designed for specific distribution circuits (outlets, lighting, small appliances). The main protection for a battery bank requires fuses or circuit breakers with a much higher amperage rating, matched to the total capacity of your batteries.

In case of a short circuit or overload exceeding 15A, the internal mechanism trips instantly, switching the lever to the off position and completely isolating the circuit from the power source.

It must be installed on your main or secondary 230 V electrical distribution panel, upstream of the equipment or sub-circuit it is intended to protect.

Yes, Mastervolt products are specifically designed for marine use. This circuit breaker is resistant to harsh conditions on board, but it must be installed in an electrical panel inside the boat, protected from direct water spray.

The ABYC (American Boat and Yacht Council) certification ensures this circuit breaker meets stringent North American marine safety standards, providing reliable protection against electrical fire risks on board.

Installation requires standard electrician tools: insulated screwdrivers, wire strippers, and terminals suitable for your cable cross-sections. No proprietary Mastervolt tools are required for wiring.

No, a standard thermal-magnetic circuit breaker like this model does not consume power to maintain its closed state. It simply allows current to pass until an anomaly triggers its mechanical tripping.

Although it operates on the same principle as a 230 V domestic circuit breaker, it is specifically designed and certified for the requirements of the marine environment. It is recommended to use it for its primary purpose: boats and recreational vehicles.

On a boat, polarity reversals at the shore power inlet are common. Cutting both live and neutral simultaneously with a double-pole circuit breaker ensures no hazardous residual voltage remains on the circuit, even if the source is reversed.
