Thermistor engine protection relays compact evaluation unit 17.5 mm housing spring train terminal 1 clasp, 1 opener US = AC / DC 24 V car RESET suitable for metal switches 2 LEDs (READY / TRIPPED) galvanic separation thermal protection relays SIRIUS 3RN2 for the protection of engines from overheating by direct temperature measurement. The direct measurement of the engine winding temperature allows the protection of an engine even under unusual conditions such as heavy-duty, braking, frequent switching or insufficient cooling and thus saves a precautionary oversize of the engine. The use of PTC sensors or bimetal switches does not require the parametrization of the devices. LEDs allow quick error diagnosis. The devices are climate-resistant, contact-safe and can be used worldwide thanks to wide-voltage range and international applications. Available as mono or bistabile evaluation equipment, with and without ATEX approval, with one or two contact groups and with car, hand and / or remote RESET. The devices are available in screw or spring drawing technology (Push-In). There are versions in construction width 17.5 mm or 22.5 mm, for hat rail TH35 or for screw fitting with adapter (accessories) and with hard-gilded contacts. Uniform accessories for all device variants, such as removable clamps, plug-in pockets and encoding stifles, simplify the selection and storage. The 3RN2 thermistor engine protection relays release the proven 3RN1 series. SIRIUS Relais - a program for all cases.
