This premium 24-volt current sensing relay is an essential electrical component designed for the automated control of secondary accessories in HVAC and appliance systems. Operating on a 50/60Hz frequency, this relay detects the flow of current in a primary circuit—such as a furnace blower motor—to automatically trigger peripheral devices like humidifiers, electronic air cleaners, or power ventilators. By ensuring that these accessories only operate when the main system is running, this relay enhances energy efficiency and protects your equipment from unnecessary wear. It is a reliable solution for low-voltage control circuits, offering a precise and durable switching mechanism for residential and commercial climate control applications.
Type: Electrical Current Sensing Relay
Size: Small
Application: Commonly used in HVAC systems to synchronize the operation of furnace accessories like humidifiers, air purifiers, and ventilation fans with the primary blower motor.
Specifications: Voltage: 24V AC; Frequency: 50/60Hz; Trigger: Current-actuated switching
