Safety temperature limiter

Abstract

Temperature control device (safety temperature limiter) for electrical devices, in particular for domestic use, with at least one circuit, with a thermal control unit, temperature controller which interrupts the circuit at an upper limit temperature and closes the same circuit again at a lower limit temperature.

Claims

[1] Temperature control device (safety temperature limiter) for electrical appliances, in particular for domestic use, with at least one circuit, with a thermal control unit, temperature controller which interrupts the circuit at an upper limit temperature and closes the same circuit again at a lower limit temperature. [2] Temperature control device according to claim 1, characterized by That is, a thermal control unit, a temperature controller, interrupts the circuit being controlled once a customer-set temperature has been reached. It closes the same circuit again once the temperature falls below a customer-set temperature (below the opening temperature). [3] Temperature control device according to preceding claims, characterized by that a second, electrically acting control unit is installed, which is activated at higher electrical currents and galvanically interrupts the circuit to be controlled. [4] Temperature control device according to preceding claims, characterized by that the second, electrically acting control unit (claim 3) is activated in the event of rapidly increasing electrical currents (short circuit) and galvanically interrupts the circuit to be controlled. [5] Temperature control device according to preceding claims, characterized by that a third thermally acting control unit is installed, which galvanically interrupts the circuit to be controlled in the event of extraordinary faults, overloads or other impairments.
