Parker-Jackes Evans 78047 AC Coil 120V H23SR

The Parker-Jackes Evans 78047 AC Coil H23SR is an electromagnetic control component that activates switching within electrical control circuits used by equipment. When supplied with 120-volt power, the coil generates a magnetic field that moves the internal actuator, allowing the associated contactor or relay to change circuit status as required. Incorporated into compatible HVAC systems, it is fitted within the control assembly where it interfaces with the electrical switching system to regulate equipment operations. Accurate electrical response supports dependable circuit control, coordinated equipment sequencing, and maintains uninterrupted operation of connected system components.
