Siemens 3un21 Manual
3RN1 thermistor motor protection relays offer substantial advantages wherever current-dependent protection with circuit-breakers or overload relays is simply not enough: in certain situations overheating of a motor may occur, which won't be detected by the thermal image in the circuit breakers or overload relays. Applications. Heavy starting (e.g. Centrifuges).
Frequency converters. Frequent switching.
Impeded cooling, e.g. Due to soiled environment (paper and textile industry, cement works). Braking operations. 'Warning and tripping' function by using two sensor circuits with different response temperatures in order to be able to react before shutdown (e.g. Switch in additional cooling, reduce load). Multimotor protection with a single device, e.g.
For conveyor lines where several motors need to be switched off simultaneously. Advantages at a glance. One device covers all motor powers. Universal use through double terminal labeling for monitoring relays and overload protection equipment. High contact stability due to models with hard-gold-plated contacts - for use under difficult conditions.
Simple and fast troubleshooting thanks to display of wire breakage and short- circuits in the sensor circuit. Wide voltage power packs reduce the number of different versions. Various technical approvals: ATEX for dust and gas, UL, CSA, several shipbuilding classifications.
