Resideo RC840T-120 Electromechanical Relay 321894-709 External Equalization: Critical for high-tonnage

External Equalization: Critical for high-tonnage systems to ensure accurate sensing of evaporator outlet pressure

providing the necessary structural integrity to secure the 1-core block within the DCR housing

Optimized Filtration: Specifically designed to capture oil mist and fine particulates to protect delicate nozzle-flapper assemblies

Designed for 460V / 380–415V three-phase operation

this centrifugal wheel is balanced to minimize vibration and reduce mechanical stress on the blower motor

Resideo RC840T-120 Electromechanical Relay 321894-709 External Equalization: Critical for high-tonnageThe Resideo RC840T 120 Electromechanical Relay with a built in 24V transformer is a critical component for integrating line voltage equipment into low voltage control systems. This switching relay operates on a 120 Vac input and provides a 24V, 40 mA, 1. 2 VA control signal, making it the industry standard for controlling electric baseboard heaters, resistive cooling loads, and inductive fan motors. The unit features an internal transformer that
