The current and temperature limiter Y is used wherever, on one hand, protection against over-temperature as well as against over-current is required, and on the other hand, automatic switch on function of the device to be protected – subsequent to a follow-on cooling down period – is prohibited or undesired.



The current and temperature limiter Y operates dependently on a power supply. The temperature is detected by means of a bimetal disk which is first specified in accordance with the required cut- off temperature. When this fixed cut-off temperature TA is reached, this bimetal disk snaps over, breaking a contact system and thereby interrupting the electric circuit of the device to be protected.
