PARAGON
Frequently asked questions
Common questions about PARAGON from 3G Electric.
What is the typical application for PARAGON defrost timers like the 8145-20M?
PARAGON defrost timers such as the 8145-20M are used in commercial refrigeration systems to control defrost cycles. The mechanical timer initiates a defrost period at set intervals—110 minutes maximum cycle time for this model—and switches the compressor off while energizing heaters. The SPDT-NO/NC contacts allow for both normally open and normally closed switching, suitable for systems requiring separate control of defrost heaters and compressor operation.
What is the difference between enclosed and non-enclosed PARAGON defrost timers?
Enclosed PARAGON defrost timers, such as the 8145-20, come with a protective housing that allows direct mounting on refrigeration equipment or walls. Non-enclosed models, like the 8145-20M, are designed for OEM integration into control panels or equipment where the timer is housed within the system. Both types offer the same mechanical timing mechanism and contact configurations, but the enclosed version provides additional protection against dust and physical damage.
Can PARAGON timers like the A1402-00 be used in heat pump systems?
Yes, PARAGON timers such as the A1402-00, with an 8-hour maximum cycle time and SPDT contacts, are suitable for heat pump defrost control. In heat pump applications, the timer initiates a defrost cycle to remove ice buildup on outdoor coils. The 120V AC rating and 15 A current capacity make it compatible with typical heat pump control circuits, though verification of voltage and load requirements is recommended.
What voltage options are available for PARAGON defrost timers from 3G Electric?
3G Electric stocks PARAGON defrost timers in multiple voltage ratings: 120V AC (e.g., models A1402-00 and 8143-00), 208/240V AC (e.g., models 8145-20, 8141-20, 8045-20, 8041-20), and 120-240V AC (e.g., model 8145-AV). This range covers common commercial and industrial power supplies, allowing selection based on facility voltage.
How do I select the correct PARAGON timer for my refrigeration system?
Selection depends on three factors: voltage, maximum cycle time, and contact configuration. For example, a system requiring a 110-minute defrost cycle at 208/240V AC with SPDT-NO/NC contacts would use the 8145-20. If the system needs two normally closed contacts, the 8141-20 (SPDT-NO/2NC) is appropriate. Always match the timer's voltage rating to the control circuit and ensure the current rating (typically 15 A) exceeds the load.
Are PARAGON defrost timers compatible with OEM refrigeration equipment?
Yes, many PARAGON timers are designed as OEM-style replacements. Non-enclosed models like the 8145-20M are intended for direct integration into equipment panels, while enclosed models can replace existing timers in field-installed systems. The mechanical design ensures compatibility with standard refrigeration control circuits, but verifying the mounting dimensions and wiring diagram against the original timer is advised.
