Disjunctor bipolar 10 A

A double-pole circuit breaker simultaneously cuts the current on both the live wire and the neutral wire. This dual interruption provides complete isolation and maximum safety, which is essential to prevent any risk of electrocution in 230 V installations aboard a boat.

This specific model has a 10A (ampere) rating. This means it will automatically cut off the circuit if the current flowing through it exceeds this limit, thereby protecting your equipment and wiring.

Yes, this double-pole circuit breaker is specifically designed for 230 V installations. It ensures secure disconnection of both poles, which is a fundamental requirement for marine alternating current (AC) systems.

Absolutely. For equipment directly connected to it (such as a lighting circuit or power outlets), this circuit breaker can perfectly serve as an on/off switch for daily use.

This circuit breaker acts as the guardian of your installation by protecting your circuits against two major risks:

Electrical overloads (when too many devices operate simultaneously on the same line). Short circuits (accidental direct contact between the live and neutral conductors).

Yes, it is certified compliant with the strictest international standards in the marine sector. It meets the requirements of CE, UL, CSA, and ABYC, ensuring safe use on the water.

Unlike a unipolar model that only disconnects the live wire, the bipolar model cuts both the live wire and the neutral simultaneously. On a boat wired for 230 V, this complete isolation is critical to prevent current leakage and ensure absolute safety for passengers.

This circuit breaker is manufactured by Mastervolt, a globally recognized brand for the reliability, robustness, and quality of its electrical equipment designed for marine applications.

It is designed to be integrated directly into the main or secondary electrical distribution panel of your vessel, enabling centralized and secure management of your various 230 V circuits.

Yes, thanks to its extremely robust design and numerous certifications (CE, ABYC, etc.), this circuit breaker can be safely integrated on both recreational boats and commercial vessels.

In case of a short circuit, the circuit breaker will trip instantly. It will switch to the off position to cut power simultaneously on the live and neutral wires, thus protecting the installation and preventing any risk of fire.

Yes, this circuit breaker is specifically designed to fit perfectly into Mastervolt distribution panels, ensuring visual consistency and optimal technical reliability of your electrical network.

The manufacturer reference (SKU) for this 10A Mastervolt bipolar circuit breaker is 70905110.

This depends on the power of your water heater. On a 230 V network, a 10 A circuit breaker can handle a maximum power of about 2300 watts. If your device consumes more, you will need to choose a circuit breaker with a higher amperage.

This circuit breaker protects against overloads and short circuits. For specific protection against earth (or hull) leakage currents, it must be used in conjunction with a residual current circuit breaker (RCCB) suited to your installation.

Working on a 230 V electrical installation aboard a boat involves significant risks. It is strongly recommended to have the installation carried out by a qualified marine electrician to ensure compliance with current standards.

The phase carries the active current from the source, while the neutral provides the return path. Cutting both simultaneously with a two-pole circuit breaker ensures that no residual voltage remains in the circuit, which is essential for safe intervention.

Although optimized for Mastervolt panels, this toggle circuit breaker has standard dimensions for marine use. It can often be installed on custom panels or other brands accepting this format, provided the cutout dimensions are verified.

This Mastervolt model is a rocker-type circuit breaker. This format provides a modern, flush-mount aesthetic on the electrical panel while being very easy to operate on a daily basis.

When a fault (overload or short circuit) causes the circuit breaker to trip, the switch physically moves from the ON position to the OFF position. This provides a clear and immediate visual indication that the circuit has been cut for safety.
