Toggle switch circuit breaker series A white - single-pole 20 A

This product is a toggle circuit breaker from BLUE SEA Systems' A series. It is white, unipolar (protects a single conductor), and has a rated current of 20 amperes. It is designed for protecting DC electrical circuits, particularly in marine environments.

This circuit breaker is rated for a maximum current of 20 amperes. It will trip automatically if the current exceeds this value to protect the circuit.

Yes, this circuit breaker complies with the requirements of the European Low Voltage Directive 73/23/EEC and 93/68/EEC, as well as the product safety specification EN 60934 for equipment circuit breakers. It is CE marked on its packaging or directly on the circuit breaker, certifying its compliance with European standards.

The main difference is that this circuit breaker is reusable. Unlike fuses, which must be replaced after tripping due to an overload or short circuit, this breaker allows manual reset after an electrical incident. This provides a more practical and durable protection solution.

This circuit breaker is specifically designed for protecting electrical circuits with direct current (DC).

This toggle circuit breaker from the A series is white.

Yes, this circuit breaker is designed to be manually reset after tripping. This allows power to be restored to the circuit once the cause of the trip has been identified and resolved.

BLUE SEA Systems Series A circuit breakers are known for their compact size and versatility. They offer a balance between space efficiency, breaking capacity, and ease of installation, making them suitable for a wide range of onboard applications. They differ from Series B (more compact, lower current ratings) and Series C (higher current ratings, multipole configurations).

Yes, this circuit breaker is specifically designed to withstand marine environments. The BLUE SEA Systems A series of circuit breakers is renowned for its robustness and reliability in these conditions.

The manufacturer/license holder of this circuit breaker is CARLING TECHNOLOGIES, INC., headquartered in the United States. BLUE SEA Systems is a recognized brand in the marine electrical equipment sector.

This circuit breaker is ideal for protecting low-power DC equipment in marine electrical systems. It is suitable for lighting, navigation instruments, or low-power pumps.

This circuit breaker is designed for low-voltage direct current (DC) electrical systems. Although the specific maximum voltage is not mentioned in the provided information, it complies with the European Low Voltage Directive, indicating its use in typical low-voltage marine applications.

Yes, designed for low-voltage DC circuits and marine applications, this circuit breaker is suitable for protecting circuits operating under common boat and recreational vehicle voltages of 12V or 24V DC.

Yes, this circuit breaker can replace an existing fuse of the same rating (20 A) in a direct current circuit. The advantage is that it is resettable, providing reusable protection without needing to replace a blown fuse.

Yes, Blue Sea Systems Series A circuit breakers are standard components for marine electrical systems. Their compact design is intended to simplify integration into marine electrical panels and control panels.
