Jistič dvoupólový 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 that only cuts one wire, this double-pole circuit breaker simultaneously cuts the live and neutral wires. This is an essential feature for effectively securing 230 V installations.

Yes, exactly. 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 cut-off of the live and neutral conductors.

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

It protects sensitive equipment and the wiring of your vessel from critical overheating, electrical overload, or fire risks due to a potential short circuit.

When installing this 2-pole circuit breaker on a 230 V system, 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 essential to disconnect the main power supply of your boat or vehicle before any handling or installation in your switchboard.

On a 230 V network, a 20 A circuit breaker can theoretically handle a maximum power of about 4600 Watts (230 V x 20 A). 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 use a qualified electrician, particularly for 230 V marine installations, to ensure compliance with safety standards.

Absolutely. Although designed to meet the demanding standards of the marine environment, this circuit breaker is perfectly suited for securing the 230 V electrical installation of recreational vehicles such as motorhomes.

Yes, provided that the technical specifications (bipolar, 20A, cut-out dimensions) match your existing equipment, this circuit breaker can perfectly replace a generic model or one from another brand in your panel.

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

Yes, with its 20A capacity, this double-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 specific marine stresses (vibrations, humidity, corrosion), thereby guaranteeing maximum safety aboard.
