three phase contactors damaged
(OP)
Dear all,
we got from a Customer of ours a picture of a Siemens contactor installed on our machine with a burnt contact.
The motor driven is 2.2 kW at 380 V 5.7 A, expected service category is a mix of AC3 and AC4 (Siemens model is 3RT1016-1BB41 which is rated 4 kW in AC3 and 2 kW in AC4). My question is since only one pole look burnt and since we have the problem on three machines (same motor, same contactor - excluding therefore motor problems) could it be that Customer line is unbalanced?
Thank you.
