The Mastervolt 5A double-pole circuit breaker is an electrical safety component designed to protect circuits against overloads and short circuits. It is specifically double-pole, meaning it simultaneously cuts the current on both the live and neutral wires, a key feature for alternating current systems, particularly 230V installations.

This Mastervolt circuit breaker has a rated current of 5 amperes (5A). This means it is designed to protect circuits where current must not exceed this value.

This two-pole circuit breaker is primarily used in 230-volt (230V) electrical systems, cutting the current on both the live and neutral wires for complete protection.

Yes, in addition to its fundamental protection function against overloads and short circuits, this circuit breaker also serves as an on/off switch for directly connected devices, such as lighting.

Yes, the Mastervolt 5A double-pole circuit breaker is specifically designed for the marine environment. Its robust design ensures reliable performance and increased durability, essential for equipment protection and vessel safety.

This Mastervolt circuit breaker meets the strictest international standards, including CE, UL, CSA, and ABYC. This compliance ensures safe and regulatory-compliant integration within your marine installation.

A single-pole circuit breaker cuts power on a single wire (typically the live/phase), while a double-pole circuit breaker, such as this Mastervolt model, simultaneously cuts power on both wires (live/phase and neutral). Double-pole circuit breakers are essential for 230V systems to ensure complete circuit isolation.

The main role of a circuit breaker is to protect the electrical circuit from current overloads and short circuits. It acts as a shutdown indicator for the system, cutting off power in case of failure to prevent equipment damage and ensure safety.

No, this double-pole circuit breaker is specifically designed for 230V systems. For 12V or 24V systems, use circuit breakers rated for these voltages.

The part number (SKU) for this Mastervolt 5A double-pole circuit breaker is 70905105.

Choosing a Mastervolt circuit breaker ensures reliable protection and compliance with international standards (CE, UL, CSA, ABYC). The Mastervolt brand is recognized for the quality and durability of its marine electrical solutions, tailored to the specific requirements of the marine environment.

Mastervolt circuit breakers are electrical components that require correct installation. While general instructions are often available, it is recommended to use a qualified professional for installing complex electrical systems on board.

A 5A circuit breaker is suitable for protecting circuits powering low-power devices, such as lighting, small chargers, fans, or other electronic equipment on board that do not exceed this current rating.

Yes, like most modern circuit breakers, this Mastervolt model is designed to be easily reset manually after tripping due to overload or short circuit, once the cause of the issue has been identified and resolved.

Yes, this circuit breaker is an authentic Mastervolt product, a manufacturer known for high-quality electrical solutions for marine applications.

In the event of a short circuit, the circuit breaker detects a sudden and dangerous increase in current. It then triggers an internal mechanism that instantly cuts off the electrical supply on the live and neutral wires, thereby protecting the circuit and connected devices.

Simultaneous disconnection of phase and neutral, a feature of bipolar circuit breakers like this one, is critical for 230V systems. It ensures complete isolation of the circuit, eliminating any risk of residual electric shock or equipment damage, even if the wiring is reversed or a fault occurs on the neutral.

Yes, Mastervolt offers a wide range of circuit breakers, including unipolar and bipolar models with various amp ratings, to suit different electrical configurations and requirements.
