Thermistor Motor Protection 3RN1 thermistor motor protective relays offer substantial advantages wherever current-dependent protection over circuit-breakers or overload relays is simply not enough: in certain situations overheating may occur, which the thermal mapping in the circuit-breakers/ overload relays is unable to detect. Application - 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 - "Warn and Break" function through implementation of two thermistors with different response temperatures - Multimotor protection with a single device, e.g. for conveyor lines where several motors need to be - - -switched off simultaneously
