Thermal motor protection relay 1 changeover contact - Motor temperature monitor 1 circuits 3RN200... – Siemens – 4047621004389: Thermal motor protection relay 1 changeover contact 3RN2000-1AA30 With removable terminals, number of measuring circuits 1, number of contacts as NC contacts 0, number of contacts as NO contacts 0, number of contacts as changeover contacts 1, connection type of auxiliary circuit screw connection, rated control supply voltage Us 24 ... 24V , type of voltage for actuation AC/DC, height 100mm, width 17.5mm, depth 90mm, thermistor motor protection relay compact evaluation device 17.5 mm housing, screw connection, 1 changeover contact, US = AC/DC 24 V, auto-RESET, suitable for Bimetallic switch, supply=output voltage, 1 LED (TRIPPED) SIRIUS 3RN2 thermistor motor protection relay for protecting motors from overheating by direct temperature measurement. The direct measurement of the motor winding temperature enables a motor to be protected even under unusual conditions such as heavy starting, braking, frequent switching or insufficient cooling and thus saves the motor from being oversized as a precaution. The use of PTC sensors or bimetallic switches means that the devices do not need to be parameterised. LEDs enable quick error diagnosis. The devices are climate-proof, safe to touch and can be used worldwide thanks to the wide voltage range and international approvals. Available as monostable or bistable evaluation devices, with and without ATEX approval, with one or two sensor circuits and with auto manual and/or remote RESET. The devices are available with screw or spring-loaded technology (push-in). There are versions with a width of 17.5 mm or 22.5 mm, for TH35 top-hat rail or for screw mounting with adapter (accessories) and with hard gold-plated contacts. Uniform accessories for all device variants, such as removable terminals, push-in lugs and coding pins, simplify selection and storage. The 3RN2 thermistor motor protection relays replace the proven 3RN1 series. SIRIUS relay - a program for all cases.
