632691R Nordyne PTCR Motor StarterÂ
Description
The 632691R is an OEM PTC motor starting resistor (PTCR relay) engineered to provide reliable startup current for PSC blower and condenser fan motors in Nordyne HVAC and PTAC equipment. It incorporates a positive temperature coefficient ceramic element (designation MZ92D-40RN) that offers low resistance during motor spin-up, then heats up to sharply increase resistance and remove the start winding once full speed is reached. Housed in a heat-resistant enclosure with a two-pin polarized connector, it supports 208–230 VAC, 50/60 Hz systems and delivers consistent performance under load.
