1) Copy following links:

2) 4003-0 is 120Volt timer so clock voltage is 120V
Timer can control 120V or 240V loads
Use diagram 3
3) Paragon is no longer making this timer or parts for timer.
If you purchased timer from ebay, then assume motor is bad or X2772 trippers are worn out.
Always buy new timers. Buy Intermatic and parts are easily available.
4) Replacement timer is Intermatic T101

As long as you get a new timer that is 220/240v and is the same amperage or larger, you should be fine. Wiring would be the same.
SOURCE: I need a wiring diagram
Paragon 8145-20 is a 240VAC (2 phase) timer. I doubt you will be able to find a 3 phase type timer.
I would suggest you use this timer as a control and purchase either contactors or relays rated to handle the 3 phase load.
SOURCE: I have a paragon 8145-20 defrost timer. do you
Link below has wiring diagrams and wiring manuals for 240V 8145-20
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost
I am not expert installing defrost timers.
According to information from Paragon, 8145 is for hot gas defrosting. 8140 series are time initiated, and pressure-or-temperature terminated.
Wiring diagram does not show compressor wired to timer.
The cycle works like this:
Timer is running but defrost is not switched ON.
Fan is ON.
Timer switches ON and activates defrost cycle.
Fan turns OFF. Hot gas valve turns ON for defrosting.
Cycle limit switch is temperature or pressure sensitive.
Cycle limit switch reaches trip point, timer switches OFF.
Hot gas valve turns OFF. Fan turns ON.
So fan is off during defrost cycle.
Hot gas valve turns ON when timer switches ON.
Timer is switched OFF by pressure-or-temperature limit switch.
