Wyłącznik nadprądowy dwubiegunowy 15 A

This circuit breaker acts as an essential safety device. It protects your marine electrical circuit against overloads and short circuits by automatically cutting off the power supply in case of a fault.

A double-pole circuit breaker simultaneously cuts power on both the live and neutral wires, providing complete isolation of the faulty circuit. A single-pole model only cuts 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 on alternating current.

Yes, exactly. For devices directly connected to it, such as a lighting circuit or power 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 network, you must absolutely connect both the live wire and the neutral wire to the circuit breaker so that 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 with a maximum consumption not exceeding this tolerance threshold.

Yes, although it is manufactured by Mastervolt, this circuit breaker uses a format that allows it to be integrated into most marine electrical panels compatible with this type of toggle module.

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

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

In the event 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 the stringent North American marine safety standards, providing reliable protection against electrical fire risks onboard.

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

No, a standard magnetic-thermal 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 release.

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

On a boat, polarity inversions at the dock terminals are common. Simultaneously cutting both the live and neutral wires with a double-pole circuit breaker ensures no dangerous residual voltage remains on the circuit, even if the source is inverted.
