Re: Looking for a connector

Mr. V,
In the paper you have linked to it is important to note that curves are only annotated to a 40 degree C rise. The UL rating for these connectors is based on a 65 degree rise. Of more interest is the pulsed current ratings for multipole connectors based on this standard. Note that with a #10 wire, the safe current is more than double the rated current when applied for less than two seconds at a time. Further derating can be included for connectors that are in the open rather than part of an assembly. For the majority of teams using these contacts for CIM motors with #12 wire for all power wiring, the series resistance of the wire, the battery, the speed controller and the contacts will limit the overall current to right around 100 amps in stall.
