Carling 70A C Series Rocker Circuit Breaker

Precision Hydraulic-Magnetic Overcurrent Protection for High-Amperage Systems

Engineered for demanding electrical environments, the Carling 70A C Series Rocker Circuit Breaker delivers reliable overcurrent protection and manual switching in a single, compact unit. Utilizing advanced hydraulic-magnetic technology, this circuit breaker provides consistent performance across varying ambient temperatures. Whether deployed in marine vessels, off-grid power setups, industrial machinery, or heavy-duty automotive applications, the C Series is built to safeguard vital wiring and equipment from electrical faults and overloads.

The Advantage of Hydraulic-Magnetic Technology

Unlike standard thermal circuit breakers that rely on heat buildup to trip, a hydraulic-magnetic circuit breaker responds purely to changes in current flow. A magnetic solenoid mechanism senses the exact amperage passing through the circuit, while a damped hydraulic fluid core regulates the trip delay during temporary, harmless inrush currents.

This operating principle solves one of the most common problems in mobile and off-grid electrical design: nuisance tripping caused by heat. When installed in hot engine bays, unventilated battery enclosures, or sun-exposed marine consoles, thermal breakers often derate and trip prematurely below their rated capacity. Conversely, in freezing conditions, they may take too long to trip, placing wiring at risk. Because the Carling C Series relies on magnetic force rather than temperature, it maintains its precise 70A trip point regardless of the surrounding climate, significantly reducing the risk of unexpected system downtime or thermal damage.

Ergonomic Design and Robust Panel Construction

Designed for seamless integration into modern electrical control panels, this C Series model features a contoured black rocker actuator that allows for smooth, positive manual operation. Doubling as a heavy-duty ON/OFF isolation switch and a protective breaker, it eliminates the need to wire separate switching and fusing components, saving valuable panel space and reducing installation complexity.

• Temperature-Independent Operation: Hydraulic-magnetic trip mechanism ensures the 70A trip threshold is unaffected by extreme ambient heat or cold.
• Dual-Purpose Rocker Actuator: Ergonomic rocker switch provides straightforward manual circuit control alongside automatic overload protection.
• High-Visibility Status Indicators: High-contrast white ON and OFF markings printed directly on the actuator offer clear, immediate visual confirmation of circuit status.
• Reinforced Panel Mounting: Equipped with brass-lined mounting holes to ensure secure, vibration-resistant installation into switchboards and dashboards.
• Compact, Durable Enclosure: Precision-moulded housing protects the internal trip mechanism from dust and physical impacts in rugged environments.

Application Considerations and System Integration

Carling Technologies designs the C Series specifically for high-amperage applications where space is at a premium and reliability is critical. This 70A model is well-suited for protecting main DC distribution feeders, high-output alternator charge lines, windlasses, hydraulic pumps, and inverter-charger sub-circuits.

Note on Electrical Ratings: While the Carling C Series family is engineered for high-amperage and high-voltage environments, the specific operating voltage and interrupt-capacity ratings for this individual 70A configuration are not specified in the provided product details. Installers and system engineers should verify that the circuit parameters align with Carling C Series technical documentation prior to integration.
