20 A double-pole circuit breaker

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, which only disconnects one wire, this double-pole circuit breaker simultaneously disconnects both the live and neutral wires. This is a critical feature for safely protecting 230 V installations.

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

These bipolar circuit breakers in this range are primarily used on 230 V electrical systems to ensure safe disconnection of the live and neutral conductors.

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

It protects sensitive devices 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 supply 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 circuit 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. Although designed for the demanding standards of the marine environment, this circuit breaker is perfectly suited for securing the 230 V electrical installation in leisure vehicles such as campers.

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

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

Yes, with its 20A rating, 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 boating (vibrations, moisture, corrosion), thus guaranteeing maximum safety on board.
