Toggle switch circuit breaker Blue Sea Series A Black - single-pole 5 A

This Blue Sea Series A toggle circuit breaker is designed to protect electrical circuits with a nominal current rating of 5 amperes (5 A). It provides precise interruption in case of overload or short circuit on circuits of this rating.

This is a unipolar circuit breaker. This means it protects and interrupts the current on a single conductor (usually the positive wire) in an electrical circuit.

This circuit breaker is compatible with low-voltage systems. Blue Sea's Series A circuit breakers are typically designed for direct-current (DC) applications up to 32V and alternating-current (AC) applications up to 120V, making them ideal for marine electrical systems.

This circuit breaker is designed for panel mounting. It requires a specific cutout in the distribution panel or dashboard to insert the breaker body, with the toggle remaining accessible on the front panel. It is recommended to refer to the cutout templates and dimensional diagrams provided in the technical documentation for precise installation.

Yes, this circuit breaker is specifically designed for demanding marine environments. The Blue Sea A series is recognized for its robustness and reliability in these conditions, providing essential protection for onboard electrical systems.

The main advantage of a circuit breaker over a fuse is its ability to be manually reset after tripping due to an overload or short circuit. Unlike a fuse, which must be replaced, the circuit breaker allows for quick restoration of the circuit, which is particularly convenient at sea.

This 5 A circuit breaker is ideal for protecting low-ampere circuits on board. It typically includes navigation lighting, small electronic instruments, low-power bilge pumps, USB chargers, or other accessories requiring individual protection.

Yes, this circuit breaker complies with the European Low Voltage Directive 73/23/EEC (updated by 93/68/EEC) and meets the EN 60934 product safety specification, which is the standard for equipment circuit breakers. It is CE marked on its packaging and/or on the circuit breaker itself.

Yes, this is a toggle-type circuit breaker, meaning it can be manually reset by toggling the switch after it has tripped to protect the circuit.

This toggle circuit breaker from the A series is black.

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

Yes, this circuit breaker is an excellent alternative to fuses. It offers the advantage of quick and manual resetting, which is more convenient and cost-effective in the long run than repeatedly replacing fuses.

Designed for marine environments, this circuit breaker is made from robust materials and a design that provides good resistance to moisture and water spray. It is suitable for use in areas where it may be exposed to these conditions.

Blue Sea Series A circuit breakers are designed for long service life. They typically withstand at least 10,000 operating cycles (trips and resets) at their rated current, ensuring durable reliability.

To choose the correct amperage, the circuit breaker must be sized to protect the wiring and equipment. The breaker's amperage must be equal to or slightly higher than the maximum continuous operating current of the circuit, but always lower than the maximum capacity of the wire used in that circuit to prevent overheating of the wiring.

Yes, if there is an available slot with the appropriate cutout dimensions on your distribution panel, this circuit breaker can be integrated. It is designed to fit standard marine distribution panels, providing granular protection for specific circuits.
