    Could Tin-Plated and Nickel-Plated Contact Materials Cause Relay Failures?

    There is a 16A load on the NO contact and 8A on the NC contact (opposing operation so not 24A passing at the same time on a 30A rated relay). It was originally built with an "automotive" female terminal at the connection point (I should mention it's an open tab relay utilizing crimped...

    Could Tin-Plated and Nickel-Plated Contact Materials Cause Relay Failures?

    Trying to troubleshoot a field failure on a purely resistive load on a 30A rated relay utilizing only a 24A load (cycled off/on for 45 min, 1x/day). Our wiring/load has been verified but this failure has been occurring sporadically but impact has been large. My question is, could a tin-plated...
