Are the 8539 NEMA 7&9 enclosure combination starters obsolete?
8538 type S starters
They are obsolete. It has become necessary for us to end the manufacturing of the Type 7 & 9 NEMA combination starters. Enclosure Types 7 & 9 are for hazardous locations and this obsolescence includes both bolted and SPIN-TOP® designs. The last day for purchase was September 2011.
