30 A double-pole circuit breaker

A double-pole circuit breaker, such as this Mastervolt model, is designed to cut the current simultaneously on both wires of a circuit, the live and the neutral. This feature is critical for 230 V systems onboard vessels, as it ensures a complete and secure circuit interruption in case of overload or short circuit, providing comprehensive protection and enhanced safety for equipment and personnel.

This Mastervolt circuit breaker is a 30-ampere (30A) model. This means it is designed to protect electrical circuits with a maximum current rating not exceeding 30A.

Yes, this Mastervolt bipolar circuit breaker is specifically designed for marine installations. It is an essential component for the safety and management of onboard electrical systems, suitable for demanding marine environments.

This Mastervolt circuit breaker complies with several international safety standards, attesting to its robustness and reliability. It meets CE, UL, CSA, and ABYC requirements.

Yes, in addition to its overload and short-circuit protection function, this circuit breaker also serves as an on/off switch for appliances directly connected to it, such as lighting. This dual function simplifies circuit control.

The fundamental difference lies in the number of poles interrupted. A single-pole circuit breaker interrupts only one pole (typically the live wire), whereas a double-pole circuit breaker, like this Mastervolt model, simultaneously interrupts both poles (live and neutral). The double-pole model provides complete protection for more complex systems, particularly 230 V systems.

The part number (SKU) for this Mastervolt 30A double-pole circuit breaker is 70905130.

This circuit breaker is a Mastervolt product, known for its power and energy independence solutions.

Yes, the primary function of this Mastervolt circuit breaker is to provide reliable protection against overloads and short circuits. It prevents damage to equipment and reduces the risk of fire in the vessel's electrical system.

No, this 2-pole circuit breaker is primarily used on 230 V AC systems. It is not designed for direct current (DC) systems such as 12 V or 24 V.

Although this circuit breaker complies with recognized safety standards (CE, UL, CSA) and handles 230 V systems, it is specifically designed and optimized for marine installations. For domestic use, it is advisable to consult local electrical codes and regulations, which may require specific types of circuit breakers.

Yes, for electrical safety reasons and to ensure compliance with current standards, it is strongly recommended to have this circuit breaker installed by a qualified professional, especially in a marine environment where requirements are specific.

This circuit breaker is designed to integrate into onboard electrical systems. Its protection and switch function simplifies the electrical panel architecture, making integration easier.

For a safe and compliant installation, the wiring used with this 30A circuit breaker must be sized to handle a continuous current of 30 amperes without overheating. It is mandatory to comply with applicable marine electrical standards when selecting cable cross-sections.

This circuit breaker enhances safety by protecting circuits from overloads and short circuits, which can damage equipment or cause fires. Its bipolar design ensures a complete power cut (live and neutral) on 230 V systems, minimizing electrical hazards.

The product context provided does not specifically mention the inclusion of a detailed wiring diagram with the circuit breaker.

Yes, like any electrical component, this circuit breaker requires adequate space for mounting and cable connections. It is typically designed to be integrated into an electrical panel or distribution board, where sufficient space must be provided for ventilation and access.
