HVAC technicians and DIYers with an electric furnace or heat pump, this is a genuine OEM sequencer relay from International Comfort Products (ICP). Sequencers are crucial – they turn the heating elements on in stages to avoid a huge power surge. This one is a 4PST (Four Pole, Single Throw) relay, meaning it can control four separate circuits. The coil voltage is 24 volts, which is the standard low voltage from your furnace's control board. It's a direct replacement part, designed to meet the exact specifications of the original. Using the correct OEM sequencer is important for the safe and reliable operation of your heating system. Always make sure the part number and configuration match the one you're replacing.
