Jistič 10 A bipolární

A double-pole circuit breaker simultaneously cuts off the current on both the live wire and the neutral wire. This dual disconnection 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 rating of 10A (amperes). 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 systems. It ensures safe disconnection of both poles, which is a fundamental requirement for marine AC networks.

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

Yes, it is certified compliant with the strictest international maritime standards in the sector. It meets CE, UL, CSA, and ABYC requirements, 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 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 conductors, thus protecting the installation and preventing any risk of fire.

Yes, this circuit breaker is specifically designed to fit perfectly 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 10 A Mastervolt double-pole circuit breaker is 70905110.

This depends on the power rating 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 paired with a residual current circuit breaker (RCCB) suitable for 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 live wire 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 optimized for Mastervolt panels, this toggle circuit breaker has standard dimensions for marine use. It can often be installed on custom switchboards 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-mounted look on the electrical panel while remaining 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.
