Customer Question

Welcome. My name is ***** ***** would be glad to assist.

Apparently, the contactor is an old one, as Siemens doesnt show it in any database that can be found as yet.

What are the connection terminal labels?

Do not need the power throughput terminals as those will be L1,L2,L3 and T1,T2 T3, just the others on the coil and latching assembly.

Normally designated with a1-a2, e1-e2 or b1-b2 etc? Or something else.

That may lead to the standard connections without needing the original spec sheet.
