I've seen quite a few post about these solenoids, so it peeked my interest. I've been talking to those guys (very nice by the way, Jeff is the owner and most knowledgeable), specifically asking about the duty cycle of that solenoid. This is what they said...
An M12000 pulls 440 amps at full capacity and this solenoid is capable of 2 minute pulls at 450 amps. That's a long constant pull at full capacity, so I think they will be well worth the money. I just got two in today (I'm running dual winches), but haven't had a chance to try them out. They are less than half the price of an Albright, so carrying a spare is actually practical. Anyone who has been running them, feel free to post what you think about them and I'll post my opinion when I get a chance to test them out.
5.3.1 Under working condition within electric current 450A, switch on one pole pass through for 5 seconds, then switch to the opposite pole pass 5 seconds, that being considered as one test circle, proceed the test except paused when temperature reach to 150℃. The test could be passed if test circles were more than 1000 times without failure.
5.3.2 Under working condition within electric current 450A, switch on one pole pass through for one minute, then switch to the opposite pole pass through one minute, that being considered as one test circle, proceed the test 10 circles. The test could be passed if tested relay was no failure.
5.3.3 Under working condition condition within electric current 450A, switch on one pole pass though for 2 minutes then paused 4 minutes, then switch to the opposite pole pass though 2 minutes. The test could be passed if tested relay was no failure.
