Trane CNT0532 Fan Limit 322838-752 Specifically calibrated for an outletThe Trane CNT0532 (often superseded by CNT00532) is a heavy duty OEM replacement fan limit switch designed for precision thermal regulation in residential and light commercial air handlers. This A R Fan Limit is calibrated for high performance safety, featuring a critical 150F Open (Op) and 130F Close (Cl) threshold. By monitoring supply plenum temperatures, the CNT0532 prevents the heat exchanger from reaching unsafe levels during heating cycles
