Divējā polātais drošinātājs 10 A

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

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

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

Yes. For equipment directly connected to it (such as a lighting circuit or power outlets), this circuit breaker can function perfectly 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 wire and the neutral).

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

Unlike a single-pole model that only disconnects the live wire, a double-pole breaker cuts both the live and neutral wires simultaneously. On a boat wired for 230 V, this complete isolation is essential to prevent current leakage and ensure absolute passenger safety.

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

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

Yes, due to its extremely robust design and numerous certifications (CE, ABYC, etc.), this circuit breaker can be safely installed on both pleasure craft 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 seamlessly into the distribution panels of the Mastervolt range, ensuring visual consistency and optimal technical reliability of your electrical network.

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

This depends on the power rating of your water heater. On a 230 V system, a 10A circuit breaker can handle a maximum power of approximately 2300 watts. If your appliance draws more, you will need to choose a circuit breaker with a higher amp rating.

This circuit breaker protects against overloads and short circuits. For specific protection against earth (or hull) current leakage, it must be paired 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 no residual voltage remains in the circuit, which is essential for safe intervention.

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

This Mastervolt model is a rocker-type circuit breaker (rocker). This design offers a modern, flush 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 lever physically moves from the ON position to the OFF position. This provides a clear and immediate visual indication that the circuit has been safely cut.
