Tvístöðutak 10 A

A double-pole circuit breaker simultaneously cuts the current on the live wire and the neutral wire. This dual cutoff 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 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 a secure disconnection of both poles, which is a fundamental requirement for marine alternating-current networks.

Yes. 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 live and neutral).

Yes, it is certified compliant with the strictest international maritime 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 230 V boat, this full isolation is critical 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 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, due 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, protecting the installation and preventing any fire risk.

Yes, this circuit breaker is specifically designed to fit seamlessly into Mastervolt distribution panels, 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 consumes more, you must choose a circuit breaker with a higher amp rating.

This circuit breaker protects against overloads and short circuits. For specific protection against current leakage to ground (or to the hull), 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 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 rocker circuit breaker has standard dimensions for marine applications. It can often be installed in custom panels or those from other brands that accept this format, provided the cut-out dimensions are verified.

This Mastervolt model is a rocker-type circuit breaker (rocker). This format provides a modern, flush-mounted look 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 off for safety.
