Product Details

Description

This heavy-duty 24-volt sequencing relay is a vital component for HVAC systems, specifically designed to manage the activation of heating elements and blower motors. As a 3-pole, single-throw (3PST) normally open relay, it ensures that high-draw electrical components are powered on in a timed sequence, preventing circuit overloads and electrical surges in residential and commercial heating units. If your electric furnace or air handler is failing to stage its heating cycles correctly, this reliable replacement relay will restore peak performance and efficiency. It features a robust design capable of withstanding the frequent switching cycles required in modern climate control systems, making it an essential part for maintaining consistent indoor temperatures.
