Toggle circuit breaker Blue Sea Series A Red - single pole 40 A

A 40-amp single-pole toggle circuit breaker is an electrical protection device designed to interrupt current in a single conductor (pole) when an overload or short circuit is detected. It thus protects the circuit and connected equipment. The 40 A rating indicates the maximum continuous current the breaker can handle before tripping.

This circuit breaker is designed to protect marine electrical circuits against overcurrent and short circuits. It ensures reliable power interruption to onboard equipment in case of a fault, preventing damage to devices or wiring.

The toggle mechanism allows simple manual switching of the circuit (open or close) and provides a clear visual indication of the circuit breaker's state. When the toggle is in one position, the circuit is closed (live), and in the other, it is open (dead or tripped).

Yes, the 7225-BSS circuit breaker complies with EN 60934 standard for equipment circuit breakers. It also meets the European low-voltage directives 73/23/EEC and 93/68/EEC.

This circuit breaker is suitable for general DC applications on board boats. It can be used to protect a wide range of equipment requiring thermal protection up to 40 amperes, such as pumps, lighting, navigation systems, or other marine electronic devices.

The 7225-BSS circuit breaker provides thermal protection. This means it trips when the current flowing through the circuit exceeds the rated value (40 A) for a given period, causing internal overheating that activates the tripping mechanism.

This circuit breaker is designed to be panel-mounted. Installation requires cutting a specific-sized opening in the panel and then securing the circuit breaker using the appropriate mounting hardware. It is recommended to consult the manufacturer-provided cutting templates and dimensional diagrams for correct installation.

This A-series circuit breaker is typically fitted with screw terminals, designed to ensure secure and reliable electrical connections with your marine system wiring.

Blue Sea Systems' Series A circuit breakers are designed to operate across a wide temperature range, typically from -40°C to +85°C. This ensures their reliability in various marine environmental conditions.

The 7225-BSS circuit breaker is a model in the Series A, designed for general DC applications up to 40 amperes. Series B circuit breakers are often used for higher ampere ratings, while Series C is hydraulic-magnetic and less sensitive to temperature. Although they perform a similar function, they have different characteristics. It is important to select the circuit breaker suited to your circuit's specific requirements.

The exact physical dimensions of this circuit breaker are detailed in the dimensional drawings available in the product's technical images. These drawings provide the precise measurements required for installation planning.

Although designed for the marine environment, it is generally recommended to install this circuit breaker in a location protected from direct weather exposure (rain, heavy spray) to maximize its lifespan and reliability. It is intended to be mounted on a panel, often inside an electrical panel or a protective housing.

Yes, this circuit breaker is manually resettable. After tripping due to an overload or short circuit, once the cause of the issue has been resolved, the user can reactivate the circuit by toggling the breaker switch.

The red color of the circuit breaker is an aesthetic feature of model 7225-BSS. In some systems, specific colors may be used to identify circuits or particular functions, but for this model, it is primarily a product designation.

A circuit breaker is a standalone circuit protection device that performs the function of a fuse by interrupting the current in case of overload or short circuit. Therefore, it is generally not necessary to use an additional fuse holder for the same circuit protected by this circuit breaker. The circuit breaker has the advantage of being resettable, unlike a fuse which must be replaced.

The choice of the circuit breaker's amp rating must match the maximum load of the circuit it protects, while being lower than the current capacity of the wiring used. A 40 A breaker like this one is suitable for circuits with a nominal consumption not exceeding this value, and whose wiring can safely handle a current greater than 40 A. It is critical to consult your equipment specifications and the cable section to determine the appropriate amp rating.
