4A USONIC Overload Switch Code: 95289679

A 4A (Ampere) overload switch is a thermal, resettable circuit breaker that immediately cuts power if the current exceeds 4 A. It protects sensitive electronics and appliances from dangerous overcurrents. It is commonly used as a manual reset fuse rather than requiring complete replacement after tripping.

How It Works

If a short circuit occurs or you plug in a device that pulls more than 4 Amps, the internal bimetallic strip heats up, bends, and breaks the circuit. Once the fault is cleared and the equipment cools, you simply press the button to restore power.
