Disjuntor bipolar 15 A

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

A double-pole circuit breaker simultaneously cuts power to 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 onboard a boat.

This bipolar model is primarily designed and recommended for 230 V electrical systems aboard vessels, ensuring maximum safety on 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 that it can cut both simultaneously in the event 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 adopts 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 done with the main power supply (shore power, generator, and inverter) completely cut off.

No, a 15A circuit breaker is intended for specific distribution circuits (outlets, lighting, small appliances). The main protection of a battery bank requires fuses or circuit breakers with a much higher amperage, matched to the overall 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 resists the harsh conditions onboard, but it must be installed on 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 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 through until an anomaly triggers its mechanical trip.

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

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