WEG Motor Thermistor Relays from HMA Flow & Industrial protect motors against thermal overload, such as caused by insufficient cooling, heavy-load starting conditions, undersized motors, increased switching frequency, single-phase operation, high ambient temperature, break operation, and unbalance, etc. PTC temperature sensors are incorporated in the motor windings to measure motor heating, allowing for direct control via the thermistor relay.
