ICHYTI 40 amp ac fuse Feature

The selection of fuse type mainly depends on the protection characteristics of the load and the size of short-circuit current. For motors and lighting branch lines with smaller capacity, fuses are usually used as overload and short circuit protection. Therefore, it is necessary to choose fuses with appropriately smaller melt melting coefficients, often using RQA series fuses made of lead-tin alloy melt. For motors and lighting mainlines with larger capacity, emphasis should be placed on short-circuit protection and breaking capacity. RM10 and RL1 series fuses with higher breaking capacity are usually selected. When the short-circuit current is very high, it is advisable to choose RT0 and RT12 series fuses with current limiting effect.

ICHYTI 40 amp ac fuse Common types

The self resetting fuse uses metallic sodium as the melt and has high conductivity at room temperature. When a short circuit fault occurs in a circuit, the short circuit current generates high temperature, causing sodium to rapidly vaporize, and the vapor state sodium appears in a high resistance state, thereby limiting the short circuit current. When the short-circuit current disappears, the temperature decreases and the metal sodium restores its original good conductivity. Self resetting fuses can only limit short-circuit current and cannot truly break the circuit. Its advantage is that there is no need to replace the melt and it can be reused.
