1. Purpose
RL8D spiral fuse is suitable for overload and short circuit protection in circuits with AC 50Hz, rated voltage of 380V, and rated current of 2-100A.
2. Structural characteristics
A fuse is composed of a fuse link and a supporting component. The fuse link has a clear indication of melting, and the insulating base of the supporting component is made of reinforced plastic with temperature resistance (over 230 ℃) and flame retardant properties, which can safely and reliably disconnect the circuit.
