Nordyne 12s20 Sequencer 5 Kw

Product Description

The NORDYNE 12s20 is an electric heat sequencer rated at 5 kW, designed to stage electric heating elements in residential electric furnaces and air handlers. Sequencers prevent all heating elements from energizing simultaneously, which would cause excessive current draw and potential tripped breakers. This unit features a 30-90 second ON delay and a 1-30 second OFF delay, providing controlled staggered startup and shutdown of heating stages. It is installed by licensed HVAC technicians as part of electric strip heat assemblies.

This sequencer is suited for residential electric heating systems where staged element activation is required to protect electrical circuits and maintain steady operation. It is typically found in electric furnaces and heat pump air handler auxiliary heat sections. The 5 kW rating makes it appropriate for single-stage or multi-stage strip heat configurations common in residential applications.

Key Features

• 5 kW heating element sequencer for controlled electric heat staging
• 30-90 second ON delay prevents simultaneous element startup and high inrush current
• 1-30 second OFF delay provides staggered element shutdown
• OEM-style replacement designed for electric furnace and air handler strip heat systems

Compatibility

Designed as an OEM-style replacement sequencer for residential electric furnaces and air handlers requiring a 5 kW heat sequencer with 30-90 second ON and 1-30 second OFF delay timing.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all electrical power to the unit before replacing the sequencer. Verify that the replacement sequencer rating matches the existing unit specifications before installation. Work should comply with applicable local electrical codes and NEC requirements for electric heating equipment.
