Description
Overview
The International Comfort Products 1398444 is a 4PST (Four Pole Single Throw) heat sequencer designed for use in electric furnaces and air handlers. Operating on a 24V control circuit, this sequencer stages the activation of electric heating elements to prevent simultaneous startup surges, protecting your electrical system and extending equipment life. It is a direct OEM replacement part engineered to meet the original performance specifications of compatible International Comfort Products equipment.
Key Features
- 4PST (Four Pole Single Throw) configuration for multi-stage heating element control
- 24V control voltage for compatibility with standard low-voltage thermostat circuits
- Stages electric heating elements to reduce inrush current and prevent circuit overloads
- OEM replacement part designed for International Comfort Products electric heating systems
- Helps extend the service life of heating elements and electrical components
- Reliable bimetal or resistive heating element design for consistent sequencing operation
Application
This sequencer is intended for use in electric furnaces, electric air handlers, and heat pump auxiliary/emergency heat strips that utilize International Comfort Products components. It ensures each heating element bank is energized in sequence rather than simultaneously, preventing nuisance tripping of circuit breakers and reducing wear on contactors and elements.
Why Choose an OEM Sequencer?
Using the correct OEM-specified sequencer ensures proper timing, voltage compatibility, and pole configuration for your specific equipment. Substituting an incorrect sequencer can lead to improper staging, reduced efficiency, or premature component failure. The ICP 1398444 is the right part for the job.
