Defrost Control Timer 8045
The Paragon 8045-00 is a defrost control timer built for commercial refrigeration systems. It manages automatic defrost cycles for walk-in coolers, freezers and display cases operating on 120 to 240 VAC supplies. The unit carries a 40 A rating and uses an SPDT contact arrangement to switch compressor or heater circuits reliably.
Steel Enclosure Wiring Access
The timer mounts inside a steel enclosure that protects the mechanism in damp kitchen or cold-room environments. Terminations accept standard wire sizes for 40 A circuits, but installers must verify local code requirements for conduit entry and grounding. The fixed 4-hour minimum interval between cycles prevents overlapping defrosts that could trip breakers.
Daily Cycle Limits Under Load
The timer allows one to six defrost events per day with each cycle adjustable from 4 to 110 minutes in 2-minute steps. During sustained operation the SPDT contacts maintain rated current without derating, and the steel housing dissipates heat from continuous 40 A switching. The mechanism is not suited for processes requiring shorter intervals or more frequent cycles.

Questions about this item
How can I verify the Paragon 8045-00 timer is working correctly after installation?
After wiring the SPDT contacts to the defrost circuit, observe the unit initiate a defrost cycle within the 1 to 6 daily cycles setting; the compressor should stop and the heater energise for the programmed 4 to 110 minute duration in 2 minute increments, then return to cooling automatically.
What components are included with the Paragon 8045-00 and what must be sourced separately?
The package contains the defrost control timer housed in a steel enclosure with time-type termination points; you must supply 120-240V AC power conductors, mounting hardware, and the refrigeration system wiring to the 40 A SPDT contacts.
Which voltage rating should I select for a 120 V AC supply versus a 240 V AC supply?
The Paragon 8045-00 is a single model rated for both 120 V AC and 240 V AC operation, so no version choice is required — wire the supply to the same terminals and set the defrost schedule using the 1 to 6 cycles per day and 4 to 110 minute duration controls.
