3RN1 thermistor motor protection devices are thermal protection devices that are suitable, in combination with type A PTC resistors (cold conductors), for monitoring the temperature of electrical drives, transformer windings, oils, bearings, air etc.
Work according to the closed circuit current principle (monostable design) and therefore self-monitoring with regard to wire breakage. Triggered when control voltage fails. Electrical separation for devices with AC control voltage. Overall width of 22.5 mm. Screw connection
