2-pole AC circuit breaker - 3-pole 415 VAC, 50 A, long-time delay

The primary function of this circuit breaker is to protect AC (alternating current) circuits aboard vessels. It safeguards the installation against prolonged overloads and short circuits, while being designed to tolerate transient overloads due to its long delay trip characteristic.

The nominal voltage of this three-pole circuit breaker is 415 VAC (Volts Alternating Current).

The rated current of this circuit breaker is 50 A (Amperes), which indicates the maximum current it can handle during normal operation.

The "triple-pole" feature means this circuit breaker is designed to protect three phases of an alternating current circuit simultaneously. It is therefore suitable for three-phase systems.

A "long trip delay" means the circuit breaker can tolerate temporary current surges, such as those occurring when starting motors or other inductive loads, without tripping immediately. It will only trip in case of prolonged overload or short circuit, ensuring service continuity.

Yes, this circuit breaker is designed for protecting AC circuits aboard vessels. It meets the requirements and constraints of marine electrical installations.

This circuit breaker is designed to handle alternating current (AC), as indicated by its VCA designation.

Yes, AC and DC circuit breakers integrated into digital power distribution systems such as Maretron’s OctoPlex, with which this breaker can integrate, are typically designed to be field-replaceable.

This circuit breaker is a Raymarine product.

In an OctoPlex system, this circuit breaker provides AC circuit protection, enabling remote shutdown and circuit status monitoring. It integrates as an essential component of AC power distribution units.

Yes, although this circuit breaker is a standalone component, it is part of the NMEA 2000® power distribution system ecosystem and can be integrated into digital switching architectures. Systems such as OctoPlex, with which it is compatible, are NMEA 2000® certified.

Yes, this circuit breaker is specifically designed to be integrated into the AC power distribution units of Maretron OctoPlex systems, providing circuit protection for 415 VAC electrical systems.

Yes, digital switching and power distribution systems such as the OctoPlex, with which this circuit breaker is compatible, can integrate with MFD manufacturers, including Raymarine Axiom, via gateway solutions like the MConnect Web Server.

No, this circuit breaker is specifically designed for 415 VAC electrical systems. It is not suitable for use in 110V or 220V systems.

This circuit breaker, or the power distribution systems it is designed to integrate into, complies with several certifications and standards, including:

CE approvedCompliant with IEC 60533 (Electrical and electronic installations in ships)Compliant with IEC 60945 (Marine navigation and radiocommunication equipment and systems)NMEA 2000® approved (Category B)Lloyd’s Type approved

No, products like this circuit breaker, if integrated into an OctoPlex system, are not ignition-protected devices.

Yes, due to the lack of ignition protection, this circuit breaker must not be installed in areas with combustible vapors.

Installation of marine electrical systems, particularly those involving high voltages and complex architectures, should be carried out by qualified installers to ensure safety, compliance with industry standards (such as ABYC, NEC, NFPA), and proper system operation.

This circuit breaker is designed as a circuit protection component within AC power distribution units. It is installed to protect electrical systems at 415 VAC and can be remotely controlled as part of a digital switching system.

Yes, periodic inspection of all mounting hardware and all connections is strongly recommended to ensure proper operation, reliability, and safety of the vessel's electrical system.
