Blue Sea 5A A-Series Single Pole Toggle Circuit Breaker - White
Blue Sea 5A A-Series Single Pole Toggle Circuit Breaker - White
Magnetic Hydraulic Overcurrent Protection & Trip-Free Safety Design

DESCRIPTION
Integrated Magnetic Hydraulic Overcurrent Protection and Switching
The Blue Sea A-Series 5A Single-Pole Toggle Circuit Breaker delivers reliable overcurrent protection and manual switching in a single, compact device. Designed specifically as the industry standard for Blue Sea Systems electrical panels, this unit streamlines your dashboard or power distribution board by eliminating the need for separate switches and fuse holders. Whether you are outfitting a marine vessel, caravan, motorhome, or custom off-grid power system, this 5A breaker ensures your low-amperage circuits remain safe and simple to control.
Why Choose a Magnetic Hydraulic Design?
Unlike standard thermal circuit breakers that rely on heat-sensitive bimetallic strips, this A-Series breaker utilises a precision magnetic hydraulic mechanism. In environments like boat engine rooms, 4WD canopies, or caravan electrical cabinets, ambient temperatures can fluctuate wildly. Standard thermal breakers can suffer from nuisance tripping in high heat or delayed tripping in extreme cold because their internal temperature affects their trip point.
A magnetic hydraulic circuit breaker responds purely to current flow rather than ambient temperature. This means it maintains a consistent 5A trip curve regardless of the surrounding climate, providing dependable protection for your sensitive electronics and wiring without false alarms.
Engineered for Safety with Trip-Free Operation
Electrical faults require immediate isolation to prevent wire damage or fire hazards. This breaker features a trip-free design, a critical safety mechanism for demanding mobile and marine electrical setups. If a short circuit or overload occurs, the internal mechanism will trip and break the circuit even if the white toggle actuator is physically held or wedged in the ON position. Once the fault is resolved, the ergonomic toggle allows for immediate manual resetting without the hassle of sourcing and replacing blown fuses.
Key Features and Benefits
- Dual Functionality: Combines manual circuit switching and 5A overcurrent protection into one space-saving unit.
- Magnetic Hydraulic Mechanism: Provides accurate, temperature-independent trip performance across varied Australian climates.
- Trip-Free Safety: Internal contacts cannot be held closed during a fault current condition, reducing the risk of equipment damage.
- Clear Visual Indication: Features a high-visibility white toggle handle with a clearly marked 5A rating on the housing for quick circuit identification.
- Robust Panel Mounting: Built with secure brass threaded mounting inserts to withstand vibration in mobile and marine applications.
- Reliable Termination: Equipped with sturdy rear wiring terminals for dependable electrical connections at the back of the breaker body.
Ideal Applications
With its 5A current rating, this single-pole breaker is well suited for protecting low-draw electronics and individual branch circuits in 12V, 24V, or AC distribution panels. Common applications include:
- Marine navigation instruments, chartplotters, and VHF radios
- Caravan and RV LED lighting circuits
- 12V cabin fans, USB charging ports, and telemetry sensors
- Custom switch panels in 4WDs, service vehicles, and off-grid power enclosures
