We are facing interlock defeat problem on the fuse switches with 3KL series with door. Even though we provide LOTO on the door handle in “0” position, we were able to close the switch. On investigation we found that padlocking mechanism on the handle (type reference 8UC6 series) is operating erratically. While checking the spares in Siemens site, we understand the product been discontinued and instead 8UC7 series is in line. We have 1000 of such modules and facing problem with these handles, which is of serious safety concern as LOTO been defeated. Few photos of the door handle is attached for your reference.My questions here ,1. Does any one face similar problems2. Is there any solution to fix in the existing handle3. Does this problem been fixed in the new handle with 8UC7 series.Appreciate your expert feedback.Thanks.
