165C Thermal Fuse 10A 250V

Thermal fuses serve as crucial safety elements that safeguard electrical circuits from overcurrent or overheating scenarios. They play a pivotal role in maintaining the integrity of the circuit by preventing potential damage and hazardous incidents.

Functionality

Thermal fuses are designed to halt the electrical current flow in a circuit when an abnormal surge in current or overheating is detected. This action helps to avert damage to circuit components due to overcurrent and also mitigates the risk of fire or other dangerous situations.

Design and Operating Principle

These fuses are usually compact in size and come in a standard cartridge or tube shape. Their functionality is based on a thermal mechanism that utilizes a bimetal disc or a heat-sensitive element. This mechanism triggers the opening of the circuit in the event of overheating or a current surge, effectively disconnecting the electrical circuit and enabling the system to resume normal operation.

Applications

Due to their reliability and cost-effectiveness, thermal fuses find extensive use in a variety of electrical devices. These include household appliances, power supplies, industrial machinery, automotive applications, and more.

Features

While the features of these fuses can differ based on specific application needs, they generally possess attributes such as:
 

• Nominal current rating
• Breaking capacity
• Operating voltage
• Operating temperature range
