DESCRIPTION
Reliable Magnetic Hydraulic Circuit Protection for AC and DC Distribution
Engineered for demanding marine, automotive, and off-grid electrical installations, the Blue Sea Systems A-Series 20A Double-Pole Toggle Circuit Breaker combines reliable manual switching with precision overcurrent protection in a single compact unit. As the industry standard for panel distribution systems, this breaker simplifies your electrical layout by eliminating the need for separate inline fuses and toggle switches.
Featuring a double-pole configuration with a mechanically linked ganged toggle actuator, this unit is typically utilised for 240V AC main circuit protection or for isolating dual-line DC circuits. If an overload occurs on either line, the internal mechanism ensures both poles trip simultaneously, isolating both the active and neutral conductors (or positive and negative lines) to protect downstream appliances and wiring.
Why Choose Magnetic Hydraulic Technology?
Unlike standard thermal circuit breakers that rely on heat-sensitive bimetallic strips, the A-Series utilises a magnetic hydraulic mechanism. Standard thermal units can suffer from nuisance tripping in hot engine bays, canopies, or sun-exposed distribution panels because elevated ambient temperatures lower their trip threshold. Conversely, a magnetic hydraulic breaker senses only the actual current flowing through the coil. This ensures the 20A trip rating remains consistent and accurate across a wide operating temperature range, making it a dependable choice for harsh Australian environments.
Built-In Safety and Compliance
To reduce the risk of electrical fires and equipment damage, this breaker incorporates a trip-free design. In the event of a short circuit or sustained fault current, the internal contacts will disconnect and cannot be manually held in the "ON" position, preventing operators from overriding the safety mechanism until the fault is resolved. Integrated brass threaded inserts allow for secure, straightforward front-panel mounting, while the high-visibility white 20A marking on the black toggle provides instant visual identification of the circuit capacity.
Key Features and Benefits
- Combined Switching and Protection: Integrates manual circuit control and overcurrent protection into one panel-mounted device, saving space and reducing wiring complexity.
- Simultaneous Double-Pole Isolation: Ganged toggle handle connects both poles, ensuring complete disconnection of both lines if a fault occurs on either side.
- Magnetic Hydraulic Operation: Delivers consistent overcurrent tripping without derating caused by high ambient temperatures in enclosed spaces.
- Trip-Free Safety Mechanism: Prevents the actuator from being forced or held on during an active fault condition, protecting wiring and connected loads.
- Panel-Ready Construction: Equipped with integrated brass threaded inserts for clean, reliable installation into custom or pre-fabricated switchboards.
- International Certifications: Meets ABYC standards, is UL 1077 recognised, TUV certified, CE marked, and CSA certified for peace of mind in professional builds.
Ideal Applications
Whether you are upgrading a marine switchboard, wiring a caravan shore-power inlet, or building an off-grid inverter distribution panel, the Blue Sea 7236B provides the durability and compliance required for critical power systems. It is particularly well-suited for protecting 240V AC main feeds where both active and neutral lines must be switched together, or for isolating sensitive dual-line DC equipment.
Upgrade your electrical distribution panel with the Blue Sea A-Series 20A Double-Pole Circuit Breaker for dependable, temperature-stable circuit protection.
