Old Glasgow Excel 200 Amp. 3 Phase fused switch.

Zoomup
Evnin' all,

                       I have a holiday chalet park with about 80+ chalets on it that I am responsible for electrically. In the main intake room there is a Delta 657 that supplies the Glasgow Excel 200 Amp three phase fused switch. I went to lubricate it today. It has a retracting handle and is very mechanical inside, with a flag that shows ON or OFF through a little window. The red phase fuse seems to be original, as is the yellow phase fuse. The blue phase fuse has been replaced at some point in time and seems newer than the other two. (Busmann DD200.)


Now what I noticed is that the fingers on the blue phase switch blades are damaged and burnt back by a mm or two. It appears that the switch has been opened on a heavy load, or that the contacts are deteriorating due to additional loads being added. Did the old fuse blow due to overheating of the contacts, or are the contacts damaged due to the fuse getting hot? Who knows?


Can we still get spare parts for this fused switch?


Thanks,


Z.

    Having today visited my local U.K.P.N. depot and spoken to an engineer, I have discovered that the Delta 657 unit is U.K.P.N.s property and contains "J.P." main fuses. I was given a helpline number to book a visit to remove the main fuses for safe repair of the 200 Amp fused switch when I can get spares for it. Eaton has replied from Hungary requesting more info. on the 200 Amp 3 phase fused switch. A depot sign at my local U.K.P.N. depot states that the number of days without an injury in the Norwich Cluster is 1687 days. Well done U.K.P.N.
