Disjuntor bipolar 20 A

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 cuts both the live and neutral conductors. This is a critical 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.

These bipolar circuit breakers 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 is fully compliant with international standards CE, UL, CSA and ABYC.

It protects sensitive devices and your vessel's wiring from critical overheating, electrical overload, or fire hazards 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 handling or installation in your switchboard.

On a 230 V system, a 20A circuit breaker can theoretically handle a maximum power of approximately 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.

Yes. Although designed to meet the stringent standards of the marine environment, this circuit breaker is also perfectly suited for securing 230 V electrical installations in leisure vehicles such as motorhomes.

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

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

Yes, with its 20A 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.

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

This certification is essential for compliance with marine electrical standards and to prevent risks of short circuits or electrical fires.

Always verify the ABYC compliance label before installation.
