Trane CNT3782 Limit Switch metal-housing design ensures a preciseThe Trane CNT3782 Limit Switch is a high reliability safety component designed for precise thermal regulation in industrial and commercial HVAC systems. This 200F CO auto limit switch operates as an SPST normally closed device, engineered to interrupt the electrical circuit when internal plenum or heat exchanger temperatures reach the 200F (93C) set point. Featuring a 30F differential, this HVAC high limit control utilizes an automatic reset
