Voltage relay with thermal protection

Thermal protection

— security system that turns off the device when heated to a critical temperature. Some models also provide a shutdown when the permissible heating rate is exceeded. This function serves as additional insurance in case of malfunctions in the relay itself (for example, if the settings are lost and the device does not respond to overload), and in case of fire (in case of fire, the equipment is supposed to be de-energized).
