MARS 33266 Relay
The MARS 33266 is a heavy-duty DPST Time Delay Relay engineered for precision timing in residential and commercial HVACR systems. As a veteran-grade electric heat sequencer relay, this component is designed to manage high-current 240V electrical loads, providing critical protection for compressors and fans by preventing short cycling. By implementing a consistent time delay for HVAC compressors, it mitigates the mechanical strain caused by rapid thermostat cycling or momentary power interruptions. The MARS 33266 relay features a solid-state PTC heater and a reliable, snap-acting disc mechanism that ensures positive make/break action across its dual poles. This non-positional relay facilitates seamless sequencing of heating elements in electric furnaces and heat pumps, maintaining system stability and operational efficiency for professionals in the field.
Key Benefits for Technicians:- Short-Cycle Protection: Actively prevents compressed restarts during power fluctuations to preserve mechanical integrity.
- Dual Pole Switching: The DPST configuration allows for simultaneous control of multiple high-voltage circuits or heaters.
- Universal Compatibility: Serves as a direct-fit replacement for various OEM HVAC time delay relays used in Carrier, Goodman, and ICP equipment.
- Precision Timing: Provides an "ON" delay of 20-70 seconds and an "OFF" delay of 20-80 seconds for optimized element sequencing.
- Rugged Construction: Built with a shock and vibration-resistant internal switch mechanism for reliable performance in high-demand environments.
What is the primary application for the MARS 33266?
This 240V time delay relay is primarily used as a sequencer in electric furnaces and heat pump blower circuits to stage heating elements and prevent electrical circuit overloads.
Can I use this relay for compressor protection?
Yes, its time-delay function is specifically designed to stop the compressor from restarting immediately after a shutdown, which is critical for preventing motor burnouts in HVAC systems.
Is the timing adjustable on this model?
No, the 33266 uses fixed, factory-set timing windows (20-70s ON / 20-80s OFF) calibrated for standard sequencing and protection requirements.
