Replace a magnetic contactor 42AF25AF by Furnas / Siemens
Recently there is sometimes a loud hum coming from an electrical box
above the dropped ceiling in our office. We went up and opened the box
and saw that it is a Siemens/Furnas 42AF25AF magnetic contactor.
I thnk it controls the 220V fluorescent lighting in the lobby.
Where can I get a replacement and is it easy to swap out myself?
Thanks
