the 211CA3/4B3/4B opens mechanically via the solenoid coil force rather than relying on line pressure

providing additional 1/2" NPT ports for more flexible gauge glass and tri-cock positioning compared to the standard casting

Optimized Set-Points: Factory-calibrated for precise actuation

Contractors often utilize this unit for interfacing electronic controllers with legacy pneumatic actuators and dampers

including large furnaces

Trane CNT0532 Fan Limit 323080-701 the 211CA3/4B3/4B opens mechanically viaThe Trane CNT0532 (often superseded by CNT00532) is a heavy duty OEM replacement fan limit switch designed for precision thermal regulation in residential and light commercial air handlers.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
