摘要: Electrical life tests in a dc contactor are performed under DC4 and DC5 conditions. Results from our observations erosion measurements compared for different silver-based contact materials. For the device used relation can be established between arc energy material loss transfer. The mechanism during make operation determines overall to larger than expected extent. Silver nickel 90/10 stands out as with lowest rate both
