Carrier HH19ZA940 Limit Switch 321142-301 The Aaon P50591 Transformer isThe Carrier HH19ZA940 Limit Switch is a critical OEM safety component engineered for precise thermal regulation within Carrier fan coil units, packaged systems, and secondary heating assemblies. This 85 140 degree limit switch operates as a normally closed (NC) safety, opening the circuit when the sensed temperature exceeds 140F to prevent heat exchanger or coil damage. Once the system cools back to 85F, the automatic reset limit switch closes the
