Rectorseal 24ZC-6 Heat Sequencer 4 Switch 2 Ti

Product Description

The RECTORSEAL 24ZC-6 is a 4-switch, 2-TI electric heat sequencer designed to stage the energizing of electric resistance heating elements in forced-air systems. Sequencers prevent simultaneous element startup, which would otherwise spike current draw and risk tripping circuit breakers. The 24ZC-6 uses a double-pole single-throw (DPST) switching configuration to control load circuits in sequence as the bimetal thermal elements heat and close. Licensed HVAC technicians install this component during both new construction and service calls on electric furnaces and air handlers.

The 24ZC-6 is suited for residential and light-commercial electric forced-air heating systems where multiple heating elements must be staged to limit inrush current. It fits applications requiring a compact, multi-switch sequencer with two timing inputs. Typical installations include electric furnaces, electric air handlers, and strip-heat packages where element staging is required to meet load management or equipment design specifications.

Key Features

• 4-switch DPST output configuration stages multiple heating elements
• Dual timing inputs (2 TI) allow coordinated staggered element engagement
• Bimetal thermal element design provides reliable, repeatable switching
• Controls inrush current by preventing simultaneous energizing of all heating strips
• Compact form factor suited for installation inside electric furnace or air handler cabinets

Compatibility

Designed as an OEM-style replacement sequencer for residential and light-commercial electric furnaces and air handlers requiring a 4-switch, 2-TI DPST heat sequencer configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect all electrical power to the unit at the breaker panel before removing or installing any sequencer. Verify that replacement sequencer switch ratings are compatible with the system voltage and amperage before energizing. Follow applicable NEC guidelines for electric heating equipment wiring and service.
