Gold mating surface and 3 A current ceiling
The 15 µinch gold over nickel on the mating face supports at least 500 mating cycles in typical field-service applications — quarterly cycling translates to over a century of service life at the contact interface. The 3 A per-contact rating is the thermal limit at the stated temperature rise; derate above 105°C ambient per the series derating curve.
