Title: Vintage ASEA EG-1 630A / 440 kW Contactor Test and Teardown
Post by: Mads Barnkob on January 13, 2021, 05:33:18 PM

2000 kg (4395 lb) would be the weight of the AC motor that this 630 A / 440 kW contactor can turn on and off. This also explains the shear size of this contactor, a almost solid piece of metals, copper coil, iron core, copper terminals, platinum contact points and aluminium enclosure.
