Schneider Electric TeSys DecaThermal Overload Relay Series (23-104 Amp)

Schneider Electric TeSys DecaThermal Overload Relay Series (23-104 Amp) thermal overload relay is a protective device used in electrical circuits to prevent damage caused by overheating. It works by monitoring the current flowing through the circuit and detecting any excessive current that could lead to overheating of the system. When the current exceeds a preset threshold for a specified period, the relay triggers a response to interrupt the circuit, thus preventing further flow of electricity.

This type of relay contains a bimetallic strip or a heating element that expands when exposed to excessive heat, causing it to actuate a switch and break the circuit. By disconnecting the power supply in case of overload, thermal overload relays help prevent damage to equipment, electrical fires, and other hazards.

Thermal overload relays are commonly used in applications such as motor protection, where they provide crucial protection against overcurrent conditions.
