130*C Thermal Fuse 2A 250v RH130 Temperature Switching / Thermal Fuse Cutoff

Thermal fuse is a safety device designed to cut off electrical power when the temperature exceeds a specified limit. The 130°C thermal fuse with specifications 2A 250V, marked as RH130, has specific characteristics and uses. Here’s a detailed breakdown:
Key Features and Specifications:

Temperature Rating:
* 130°C: This indicates the thermal fuse will activate and interrupt the electrical circuit when the surrounding temperature reaches 130 degrees Celsius.

Current Rating:
* 2A: This specifies that the fuse can safely handle currents up to 2 amperes. If the current exceeds this limit, the fuse may blow to protect the circuit.

Voltage Rating:
* 250V: This indicates the maximum voltage the thermal fuse can handle. It is rated for use in circuits up to 250 volts.

Construction and Operation:

Thermal Mechanism: Inside the thermal fuse, there is a temperature-sensitive element that melts when the specified temperature (130°C) is reached. This melting breaks the electrical connection, effectively cutting off the power to prevent overheating and potential fire hazards.
Non-Resettable: Once the thermal fuse has blown due to high temperature, it cannot be reset and must be replaced.

Applications:

Home Appliances: Commonly used in devices such as hairdryers, coffee makers, toasters, and irons to prevent overheating.
Power Supplies: Ensures that power adapters and other power supply units do not overheat.
Transformers: Protects against overheating in transformers used in various electronic equipment.
Motors: Used in electric motors to prevent damage due to excessive heat.
Lighting Fixtures: Ensures that lights and their components do not overheat, which can be particularly important in enclosed spaces.
