Paragon 8145-20M Defrost Timer
The Paragon 8145-20M is a defrost control timer designed for refrigeration systems that require automatic defrost cycling. It operates on 120 to 240 VAC supply voltage and handles up to 40 amps through its SPDT contact arrangement. This timer suits commercial refrigeration equipment needing scheduled defrost management.
SPDT contacts and 40 amp rating
The unit uses a single-pole double-throw contact configuration rated for 40 amps at 208 or 240 volts AC. It initiates defrost cycles based on temperature or pressure termination signals rather than a fixed time-only method. No enclosure is included with the timer body itself.
One to six daily cycles with four-hour spacing
Users can programme between one and six defrost cycles per day with a minimum four-hour interval between successive cycles. Each defrost period lasts from 4 to 110 minutes adjustable in two-minute increments. This scheduling flexibility supports sustained operation across varying frost load conditions.

Questions about this item
How do I wire the 120-240VAC supply to the Paragon 8145-20M and what is the common mistake?
Connect line voltage to the timer motor terminals and the load to the SPDT contacts rated at 40A; the step often missed is setting the defrost initiation pins for 1 to 6 cycles per day with at least 4 hours between successive cycles.
What maintenance does the 8145-20M defrost timer require over its service life?
The timer has no user-serviceable parts; plan to replace the entire unit if the motor fails or the contacts wear after extended 40A switching duty.
What is the first limit reached during continuous operation of the Paragon 8145-20M?
The defrost duration caps at 110 minutes in 2-minute increments, so the maximum single defrost cycle length is the first hard limit encountered.
