Electric Furnace Sequencer PROTACTOR Four Switch 24V Relay for 20KW

Description

Product Overview

The PROTACTOR Electric Furnace Sequencer is engineered to meet the demanding requirements of modern HVAC systems, especially those powering 20 kW furnaces. Constructed with high‑conductivity copper contacts, the unit delivers consistent electrical performance while minimizing resistance and heat buildup. The four‑switch configuration provides independent control of heating elements and the blower fan, allowing precise sequencing that improves overall system efficiency. Designed for a 24 V coil voltage, the sequencer integrates seamlessly with standard furnace control boards, and its quick‑connect terminals (marked M1‑M2, M3‑M4, M5‑M6, and M7‑M8) enable rapid wiring and serviceability. The socket‑mount style ensures a secure, vibration‑resistant fit within the furnace panel, while the compact 3.11 × 3.11 × 3.11 inch package dimensions keep the overall footprint minimal. With a maximum and minimum switching voltage of 24 V, the device operates reliably across the full range of typical furnace control voltages. The unit weighs only 5.6 ounces, making it lightweight yet robust, and it complies with industry standards for safety and durability.

Usage

This sequencer is ideally suited for residential and light‑commercial heating applications where precise control of multiple heating elements is essential. Installers will find it particularly valuable in furnaces that employ a four‑stage heating strategy, as the sequencer can independently activate each stage in the correct order, preventing simultaneous overload and extending component life. The quick‑connect terminals reduce installation time, allowing technicians to complete wiring in minutes rather than hours, which translates to lower labor costs and faster system commissioning. The device is compatible with a wide range of furnace brands, including Coleman, York, Evcon, Luxaire, Goodman, Amana, Janitrol, B12565, Rheem, Ruud, and Weatherking, making it a versatile replacement part for many OEM sequencers. Its reliable operation under continuous duty cycles makes it suitable for both new installations and retrofit projects, ensuring consistent heating performance throughout the heating season.
