Quick-connect circuit breaker with only push-button reset - 7 A

A push-button reset-only circuit breaker is a circuit protection device that automatically trips in case of overcurrent. To restore power after a trip, you must manually press the reset button. It does not function as an on/off switch.

The main function of this circuit breaker is to protect marine electrical circuits against overcurrent and short circuits. It automatically interrupts the current flow to prevent damage to equipment and wiring, providing enhanced safety on board.

Yes, this circuit breaker is specifically designed for marine environments. Its design and materials are selected to withstand harsh conditions such as humidity, salt spray, and vibrations, ensuring reliability and durability.

The BLUE SEA 7053-BSS circuit breaker is a thermal circuit breaker. It uses a bimetal strip that deforms and opens the circuit when the temperature from an overcurrent exceeds a predefined threshold, thus protecting the system.

The exact dimensions of the circuit breaker, including the space required and the cutout needed, can be found in the detailed technical drawing provided in the product media section.

No, this circuit breaker is of the 'reset only' type. This means it must not be used as an on/off switch to control power to a device. Its sole function is to protect the circuit and allow manual reset after a trip.

This circuit breaker has a rated current of 7 amperes (7 A). It is designed to trip when the current in the circuit exceeds this value, thereby protecting the connected equipment.

This circuit breaker features quick-connect terminals, typically spade terminals, which simplify and speed up cable connections. Simply insert the corresponding cable spade terminals into the breaker's terminals to establish the connection.

This circuit breaker is ideal for local and immediate installation, close to the equipment it protects. It can be mounted in confined spaces, on a dashboard, console, or directly next to the device such as auxiliary lighting, small-capacity pumps, or USB chargers.

Installing this quick-connect circuit breaker typically does not require any specific tooling beyond basic marine electrical wiring tools, such as a crimping tool for terminals, a screwdriver (if a mounting bracket is needed), and a cutting tool if a flush-mount installation is planned.

The circuit breaker can be installed via a cutout in a panel. The exact mounting details, including cutout dimensions and fastening method, are typically provided in the technical diagrams supplied with the product.

For a simple thermal circuit breaker like the 7053-BSS, polarity is generally not a critical factor for its operation. However, it is always recommended to follow established wiring conventions for a clean installation compliant with maritime standards.

Although designed for the marine environment, it is recommended to install this circuit breaker in a location protected from direct and continuous water spray to maximize its lifespan and reliability. In highly exposed areas, additional protection may be required.

This circuit breaker is generally compatible with marine DC electrical systems of 12V DC, 24V DC or 32V DC. It is essential to always check the manufacturer’s full technical specifications to confirm the maximum supported voltage for the 7053-BSS model.

This circuit breaker is ideal for protecting a wide range of low-power DC equipment, such as:

Auxiliary lightingSmall-capacity pumps (for example, secondary bilge pumps)USB chargersSecondary electronic navigation equipmentOther accessories requiring individual 7-amp protection.

No, this circuit breaker is specifically designed for direct current (DC) systems commonly found on boats (12 V, 24 V, 32 V DC). It must not be used for alternating current (AC) applications.

No, a 7-amp circuit breaker is too weak to protect a main electric motor or high-power equipment. Main motors require much higher-rated circuit breakers or fuses, sized for their starting and operating current. This circuit breaker is intended for low-power auxiliary circuits.

Yes, this circuit breaker can replace a 7 amp fuse in a DC circuit. The advantage is that it can be manually reset after tripping, eliminating the need to physically replace a blown fuse. It provides equivalent overcurrent protection.

Blue Sea Systems products are generally designed to comply with relevant maritime standards, such as those from ABYC (American Boat and Yacht Council) and SAE (Society of Automotive Engineers) for thermal circuit breakers. This ensures their reliability and safety in marine applications.
