Paneltronics 'A' Frame Magnetic Circuit Breaker - 25 Amps - Single Pole

The Paneltronics 'A' Frame Magnetic Circuit Breaker – 25 Amps – Single Pole (MPN 206-074S) is an essential protection device for marine and automotive electrical systems where reliable overcurrent defense is non-negotiable. Whether you're upgrading a vehicle's auxiliary power distribution, installing a custom battery management system, or protecting high-amperage circuits in an RV or boat, this single-pole breaker delivers consistent performance in demanding environments.

Built to marine-grade standards, it's the component serious fabricators and mechanics specify when safety and longevity matter. Magnetic circuit breakers operate via a solenoid coil that responds instantly to fault currents, making them ideal for inductive loads and transient spikes common in automotive wiring harnesses. At 25 amps, this breaker protects moderate-to-heavy auxiliary circuits—auxiliary battery banks, inverter feeds, winch motors, or integrated lighting arrays—without nuisance tripping under normal operating conditions.

The 'A' frame design ensures compact mounting on standard distribution panels, while the single-pole configuration simplifies integration into positive-leg protection schemes typical of 12V and 24V vehicle electrical architectures. Its lightweight footprint (0.2 lbs) and 2×2×2-inch envelope make it practical for space-constrained engine bays or custom dash panels. Off-road enthusiasts, custom fabricators, and restoration specialists rely on Paneltronics breakers when retrofitting their vehicles for enhanced safety and performance.
