oil-filled metal casing designed for superior heat dissipation and environmental resistance

preventing repeated cycling under fault conditions

Integrated Bracket System: Simplifies the mounting process when adapting a digital thermostat to a standard vertical or horizontal junction box

typically featuring a 135°F trip point to prevent heat exchanger damage and unsafe operating conditions

Automatic Reset: Resets at 160°F to resume normal operation once internal temperatures have stabilized

Trane CNT3781 Limit Switch oil-filled metal casing designed forThe Trane CNT3781 is a precision engineered 180F CO Auto Limit Switch designed for high reliability thermal protection in commercial and industrial HVAC systems. Featuring a non adjustable fixed trip point at 180 degrees Fahrenheit, this high limit safety control occupies a critical role in the safety circuit, preventing heat exchanger damage by breaking the circuit upon detecting excessive discharge or internal temperatures.
