WebFeb 27, 2007 · nightfox1925 (Electrical) (OP) 29 Jan 07 02:54. Our contract requirements requires even a 5.5kW LV Induction Motor to have PTC Thermistors in a separate terminal box. One of our motor vendors applies for waiver because their PTC Thermistor connection are inside the motor main terminal box (with the motor main terminals). WebAug 8, 2024 · SOME brands and models of VFD have an input for a PTC thermistor built into the drive control terminals, but some do not. The motor or equipment mfr has no control over what brand of VFD you use, so they require that a PTC relay be used, that way the system design is brand / model agnostic.

WebFeb 5, 2012 · As the motor starts, the PTC thermistor heats up and at one point switches to a high resistance state. The time needed for this to occur is calculated based on the required motor startup time. Once heated up, the current through the PTC thermistor becomes negligible and this shuts off the startup winding current. WebProtecting motors from overheating The thermistor motor protection relays of the CM-MSx.xx range monitor the winding temperature of motors which have PTC temperature sensors installed. These sensors are incorporated in the motor windings thus measuring the motor heat directly.
