Automatic Disconnect Switch Added to Car Bottom Vacuum Furnace Caption: Load car entering switch

Solar Manufacturing Inc. has designed and installed an automatic disconnect switch into a production car bottom vacuum furnace at Solar Atmospheres in Souderton, Pa. The automatic disconnect switch saves a tremendous amount of time by eliminating the labor-intensive manual maneuver of disconnecting and then re-connecting the power terminal bars at each end of the car bottom on each production run. The switch is rated for 1,000 amps, 50V AC per pole, and the switches are installed at each end of the hot zone. Not only have the disconnect switches performed as well as expected since installation, but they also have improved production.

Solar Manufacturing designs and manufactures a wide variety of vacuum heat treating, sintering, and brazing furnaces and offers replacement hot zones, spare parts, and professional service.
