This circuit breaker is an essential safety device designed to protect the electrical circuit of your boat or recreational vehicle from overloads and short circuits. It acts as a true shield for your onboard equipment.

Unlike a single-pole model that only cuts one wire, this double-pole circuit breaker simultaneously disconnects the live and neutral conductors. This is an essential feature for safely protecting 230 V installations.

Yes, absolutely. Its robust rocker mechanism allows it to be used as a manual on/off switch for equipment directly connected to it, such as lighting or a power outlet circuit.

The bipolar circuit breakers in this range are primarily used on 230 V electrical systems to ensure a secure phase and neutral cut-off.

Yes, this Mastervolt circuit breaker meets the strictest requirements for the marine environment. It is fully compliant with international standards CE, UL, CSA, and ABYC.

It protects your sensitive equipment and your vessel’s wiring from critical overheating, electrical overload, or fire caused by a potential short circuit.

When installing this double-pole circuit breaker on a 230 V network, you must connect both the live wire and the neutral wire, as the device is designed to cut both lines simultaneously in case of a fault.

Yes, for obvious safety reasons, it is imperative to cut the general electrical power of your boat or vehicle before any manipulation or installation in your switchboard.

On a 230 V system, a 20A circuit breaker can theoretically handle a maximum power of about 4600 Watts (230V x 20A). Ensure the total power of devices connected to this line does not exceed this value.

Yes, the rocker mechanism of this Mastervolt circuit breaker is particularly robust and designed to withstand regular use, especially if you use it as the main switch for some of your circuits.

Although installation is standard for this type of component, it is strongly recommended to hire a qualified electrician, particularly for 230 V marine installations, to ensure compliance with safety standards.

Absolutely. While it is designed to meet the stringent standards of the marine environment, this circuit breaker is perfectly suited for securing the 230 V electrical installation in leisure vehicles such as campervans.

Yes, as long as the technical specifications (bipolar, 20A, panel cut-out dimensions) match your old unit, this circuit breaker can fully replace a generic or other-brand model in your electrical panel.

Yes, it is fully compatible with a lighting circuit. It will optimally protect the line and can even act as a main switch to turn all connected lights on or off.

Yes, with its 20 A capacity, this 2-pole circuit breaker is ideal for protecting a 230 V power outlet circuit on board, allowing you to safely plug in everyday appliances.

The ABYC (American Boat and Yacht Council) certification ensures the component has been tested and approved to withstand the specific stresses of navigation (vibrations, moisture, corrosion), thereby guaranteeing maximum safety on board.
