WebType C Fuses. A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the … WebMay 6, 2024 · The basic operation is that the resistance of the fuse is dependent on the current flowing through it. There are two currents associated with a resettable fuse. Hold current and trip current. When the current through the fuse is lower than the hold current, the fuse will have a low resistance, and will act similar to a short circuit.

Weband allows a small trickle current to pass through the circuit. The fuse will reset to a low-resistance state after a short time when the heat or fault current is removed and/or the power is switched off [11]. Typically, the hold current is half of the trip current [11]. When the current is higher than the trip current, the fuse will trip.
