Product Details

Description

This professional-grade Current Relay Sensor is an essential electrical component designed for precision monitoring in HVAC systems. It functions as a current-sensing switch, detecting electrical flow to safely trigger or deactivate auxiliary equipment when a primary motor is running. Ideal for use in furnaces, air handlers, and air conditioning units, this relay ensures synchronized operation between system components. If your appliance is failing to activate secondary devices like humidifiers or electronic air cleaners, this reliable current sensor is the ideal replacement part to restore system efficiency and prevent electrical malfunctions.
