Overview
The Impervitran B045-0461-8 is a 45 VA, 60 Hz control transformer manufactured by Micron Industries. This fully encapsulated control transformer steps down 208/230/460V primary input to 120V secondary output, making it suitable for powering control circuits, relays, solenoids, and other industrial equipment. The B045-0461-8 is part of Micron’s proven 600 volt class ImperviTRAN line, trusted across industrial and commercial automation for four decades.
