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 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 from overcurrent and short circuits. It ensures reliable power cutoff to onboard equipment in case of a fault, preventing damage to devices or wiring.

The toggle mechanism provides simple manual switching of the circuit (on or off) and gives 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 (off 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 ideal for general DC applications onboard boats. It can be used to protect a wide range of equipment requiring thermal protection up to 40 amps, 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, then securing the circuit breaker using the appropriate mounting hardware. It is recommended to consult the manufacturer's cutout templates and dimensional diagrams for correct installation.

This circuit breaker from the A series 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 within 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 an A-series model designed for general DC applications up to 40 amperes. Series B circuit breakers are often used for higher ampere ratings, while the C series is hydraulic-magnetic and less sensitive to temperature. Although they serve 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 switchboard or a protective enclosure.

Yes, this circuit breaker is manually resettable. After tripping due to 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 the 7225-BSS model. 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 same function as 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 circuit breaker's amperage rating must match the maximum load of the circuit it protects, while being below the wiring's current capacity. A 40 A breaker like this one is suitable for circuits with a nominal consumption not exceeding this value, and where the wiring can safely handle a current higher than 40 A. It is critical to check your equipment specifications and the cable section to determine the appropriate amperage.
