AC Circuit Breaker Gen 2 - Bipolar 230 VAC, 25 A, long time delay

Raymarine's Gen 2 2-pole AC circuit breaker is designed to protect AC circuits aboard vessels. It provides essential protection against electrical overloads and short circuits, preventing damage to equipment and cables.

This circuit breaker is designed to operate on alternating current (AC) systems with a rated voltage of 230 VAC, making it suitable for European marine electrical installations.

This circuit breaker has a rated breaking capacity of 25 amperes (A). It is designed to trip and interrupt the circuit if the current exceeds this value for an abnormal duration.

A 'double-pole' circuit breaker means it simultaneously cuts both live conductors (phases or phase and neutral) of an AC circuit when it trips. This ensures complete isolation of the load from the electrical network, enhancing safety.

A 'long delay trip' means the circuit breaker is designed to tolerate currents slightly above its rated value for a short period without tripping immediately. This is particularly useful for marine equipment that may have high transient inrush currents at startup (such as motors), preventing nuisance tripping while ensuring protection against prolonged overloads.

This circuit breaker is specifically designed for marine applications and ship electrical installations. Its robustness and electrical characteristics (230 VAC, double-pole) make it suitable for a wide range of boats equipped with compatible AC systems.

Although this circuit breaker is designed for the marine environment, specific certifications (such as CE, IEC60533, IEC60945, or Lloyd’s Type Approved) are not explicitly confirmed for this Raymarine model in the provided documentation. It is recommended to verify local or installation-specific certification requirements.

Yes, this is a Gen 2 circuit breaker. This designation typically indicates a modern design and compatibility with current power distribution systems, potentially offering performance or integration improvements over previous generations.

In the event of a short circuit, an excessive and dangerous current flows through the circuit. The circuit breaker is designed to detect this sudden and rapid increase in current and trip instantly to cut off the power supply, thereby protecting the cables and connected devices.

A double-pole circuit breaker provides enhanced safety by simultaneously disconnecting both active conductors of the circuit (live and neutral or both live conductors). This ensures a complete disconnection of the load from the electrical network, eliminating any risk of residual voltage on the protected equipment, unlike a single-pole circuit breaker which only disconnects one conductor.

No, this circuit breaker is specifically designed and rated for 230 VAC AC systems. It must not be used in a 110 VAC system, as this could result in incorrect operation or insufficient protection.

This circuit breaker is an electrical protection component. Its compatibility with NMEA 2000 monitoring systems depends on the AC distribution unit or electrical panel it is connected to. The circuit breaker itself does not directly integrate NMEA 2000 communication capabilities.

This circuit breaker is a standardized component for 230 VAC systems. It may be compatible with AC distribution panels from other brands, provided the electrical specifications (230 VAC, 25 A, bipolar) and physical dimensions match the host panel. It is recommended to verify the distribution panel specifications before installation.

This circuit breaker must be installed by a qualified professional in compliance with current marine electrical standards (such as ABYC, NEC, NFPA for the United States, or equivalent European standards). It must be mounted in a suitable AC distribution panel and wired correctly to ensure effective and safe circuit protection.

Yes, this circuit breaker can replace an existing one if the electrical specifications (230 VAC, 25 A, bipolar) and physical dimensions are identical or compatible. It is essential to ensure the new circuit breaker meets the protection requirements of the circuit it is intended to protect. The main power supply must be disconnected before any work.

Circuit breakers are generally low-maintenance devices. It is recommended to perform periodic visual inspections to ensure connections are tight, that there are no signs of corrosion or physical damage. If frequent tripping occurs, the cause of the overload should be diagnosed rather than considering the circuit breaker faulty.

The lifespan of a marine circuit breaker depends on many factors, including the frequency of trips, environmental conditions, and the quality of the installation. Designed for the marine environment, it is built to be durable. In the absence of faults or extreme overloads, a circuit breaker can operate reliably for many years.

Designed for the marine environment, this circuit breaker is made with materials and finishes that provide corrosion resistance typical of saltwater environments. However, correct installation in a suitable panel and protection against direct splashing of salt water will help extend its lifespan.

Yes, like most modern circuit breakers, this one is designed to be manually reset after tripping. Before resetting it, it is essential to identify and correct the cause of the trip (overload or short circuit) to prevent immediate tripping again or further damage.

The provided documentation does not specify whether mounting accessories are included. Typically, circuit breakers of this type are sold standalone, and mounting accessories (screws, nuts, etc.) are either supplied with the distribution panel in which they are installed or must be purchased separately.
