2-pole AC circuit breaker - 3-pole 415 VAC, 40 A, long time-delay

The primary role of this Raymarine circuit breaker is to protect onboard alternating current (AC) electrical circuits from overloads and short circuits. It thereby contributes to the safety of the electrical installation and the protection of the vessel's equipment.

This circuit breaker is specifically designed for alternating current (AC) installations. Its designation "415 V AC" clearly indicates its use for AC systems.

The rated voltage supported by this circuit breaker is 415 VAC (Volts Alternating Current). It is designed to operate effectively at this voltage.

This circuit breaker is designed for a rated current of 40 A (Amperes). It provides protection for circuits where the electrical load does not exceed this value during normal operation.

The "long delay trip" characteristic means the circuit breaker is designed to tolerate high transient currents for a short period before tripping. This is particularly useful for equipment with high inrush currents at startup, such as electric motors or certain transformers, preventing nuisance tripping.

This circuit breaker is a three-pole type, making it specifically suited for three-phase electrical systems. It is not designed for single-phase installations.

This circuit breaker is intended for use in embedded marine electrical installations. It is an essential component for managing onboard power on vessels.

This circuit breaker can protect various marine AC-powered equipment, particularly those with significant electrical loads or high inrush currents, such as motors, pumps, air conditioners, or certain onboard transformers.

Yes, like most modern circuit breakers, this one is designed to be manually reset after tripping due to an overload or short circuit, once the cause of the fault has been identified and corrected.

This circuit breaker is a Raymarine product.

This circuit breaker must be installed in a marine electrical panel. Correct installation is critical for the safety and stability of the vessel's electrical system.

Yes, it is important to ensure that all connections are secure and that the circuit breaker is installed in compliance with current marine standards, such as those from ABYC (American Boat and Yacht Council) or NFPA (National Fire Protection Association). Additionally, it is recommended to periodically check the mounting hardware and connections.

Available information does not indicate that this circuit breaker is a flame-retardant device. It must therefore not be installed in areas where combustible vapors may be present, in accordance with general safety rules for marine electrical equipment.

This circuit breaker is a standard electrical protection component. While it may be integrated into electrical panels that are part of digital energy management systems, its direct compatibility with specific protocols (such as NMEA 2000) will depend on the AC distribution unit to which it is connected, not the circuit breaker itself.

No, this circuit breaker is rated for a nominal voltage of 415 V AC. Using it with a lower voltage such as 230 V AC would not provide optimal protection and may not comply with the safety standards for which it was designed.

Although its electrical characteristics (415 VAC, 40 A, three-pole) may suit certain industrial applications, this circuit breaker is specifically designed and rated for marine electrical systems, meeting the constraints and standards of this environment.

Yes, this circuit breaker is designed to protect circuits with a rated current up to 40 A. It can be used for circuits with an operating current below 40 A, but it is critical to ensure the circuit breaker is correctly sized for the specific load to guarantee effective protection against overload or short circuit.

Specific details regarding the duration and terms of the warranty for this Raymarine circuit breaker are not provided in the product description. It is recommended to consult the general sales conditions or contact customer service to obtain these details.

The provided information does not specify whether the circuit breaker is supplied with terminal blocks or additional connection accessories. Typically, these components are purchased separately or are part of the electrical panel in which the circuit breaker is integrated.

Yes, given the nature of marine three-phase high-voltage electrical systems (415 VAC) and the importance of onboard safety, it is strongly recommended to use a qualified marine electrician for the installation of this circuit breaker to ensure installation compliance with standards and safety.
