Enviro-Tec PE-09-0125 Limit Switch L125-20F

The Enviro-tec PE-09-0125 Limit Switch is a temperature switching component to open or close electrical circuits based on preset thermal conditions. It responds at a calibrated 125F setpoint with a 20F differential, allowing controlled circuit switching during temperature changes. In HVAC systems, it is used in air handling units, duct heaters, and packaged equipment where temperature thresholds need to be monitored for operational control across airflow and heat exchange sections. The switch is positioned where temperature variation directly influences system response during heating or airflow regulation cycles in equipment assemblies.
