Blue Sea 7222 AC/DC Single Pole Magnetic World Circuit Breaker - 30AMP

The Blue Sea 7222 AC/DC Single Pole Magnetic World Circuit Breaker - 30AMP is an essential protection device for vehicle electrical systems, custom builds, and mobile installations that demand reliable overcurrent defense. This circuit breaker is specifically designed for 30-amp applications, making it ideal for wiring truck bed power systems, upgrading camper auxiliary battery banks, or installing auxiliary lighting and winch circuits.

Built to handle high-draw devices, this single-pole magnetic circuit breaker operates on both AC and DC power. Its magnetic trip mechanism responds instantly to short circuits and current spikes, providing superior protection compared to older thermal-magnetic designs. This ensures the safety of sensitive aftermarket electronics, LED systems, and auxiliary battery chargers.

The compact form factor (3 x 1 x 4 inches) allows for easy installation in cramped spaces such as engine bays, battery boxes, and underseat power distribution panels. The manual reset feature enables users to diagnose faults before re-engaging the circuit, making it a valuable tool for mechanics and fabricators who require reliable auxiliary circuits in their vehicles.
