Paneltronics 'A' Frame Magnetic Circuit Breaker - 30 Amps - Single Pole

The Paneltronics 'A' Frame Magnetic Circuit Breaker – 30 Amps – Single Pole (MPN 206-075S) is a compact, reliable overcurrent protection device purpose-built for marine, RV, and automotive electrical systems where space and weight are critical. As a mechanic working on custom builds and retrofits, you'll recognize this as an essential component for protecting auxiliary circuits, winch systems, auxiliary lighting rigs, and custom battery banks from dangerous overcurrent conditions. Unlike traditional fused systems that require replacement after each fault, a magnetic circuit breaker trips instantly and resets, making it ideal for high-draw applications where reliability cannot be compromised.

This single-pole breaker utilizes magnetic-trip technology that responds instantaneously to short circuits and dangerous current spikes, protecting wiring and components from heat damage and potential fire. The 30-amp rating handles substantial loads while remaining compact at just 1 x 1 x 1 inches and weighing only 0.2 lbs—critical for dash, battery box, and panel installations where real estate is precious. The 'A' Frame design integrates seamlessly into Paneltronics panel systems and accepts standard bus configurations, allowing you to build modular power distribution architectures without custom fabrication. Thermal-magnetic protection combines the sensitivity of magnetic tripping for high-fault currents with thermal response for persistent overloads, ensuring your harness and components are protected in both catastrophic and gradual failure scenarios.

Install this breaker in custom auxiliary circuits, aftermarket winch systems, upgraded lighting setups, or secondary battery distribution on trucks, off-road vehicles, and marine platforms. It's particularly valuable for fabricators and restoration shops building modern electrical architectures into classic vehicles, where legacy fuse blocks cannot handle contemporary power demands. The manual-reset mechanism gives you instant feedback on faults—a tripped breaker signals a problem immediately, allowing diagnostic access before damage cascades. Pair this with quality marine-grade cabling and your custom electrical system gains the professional-grade protection that separates safe, field-proven builds from problematic aftermarket installations.
