Thermal Cut off Switch 2A 250V Refrigerator Auto Fuse Home Appliance Parts

Short Description:

Introduction：Thermal Fuse

A thermal fuse is a new type of electrical overheating protection element. This kind of element is usually installed in heat-prone electrical appliances. Once the electrical appliance fails and generates heat, when the temperature exceeds the abnormal temperature, the thermal fuse will automatically fuse to cut off the power supply to prevent the electrical appliance from causing a fire.

Function: cutoff the circuit by detecting overheat.

Applications

The purpose of a Thermal fuse is typically to be a cutoff for heat producing devices. As the name implies, thermal fuses are usually found in heat-producing electrical appliances such as coffee makers and hair dryers. They function as safety devices to disconnect the current to the heating element in case of a malfunction (such as a defective thermostat) that would otherwise allow the temperature to rise to dangerous levels, possibly starting a fire.

Working Principle

Before the hot fuse is started, the current flows from the left lead to the star reed and through the metal shell to the right lead. When the external temperature reaches a predetermined temperature, the melt melts and the compression spring becomes loose. Namely, the spring expands, the star reed is separated from the left lead, and the current between it and the left lead is cut off.
