Schneider Electric 9001KS12BH13 Selector Switch

The Square D 9001KS12BH13 Selector Switch from Schneider Electric is a heavy-duty, 2-position maintained knob switch designed for manual machine mode selection in industrial control panels, operator stations, and equipment requiring robust, reliable switching. Built in the 9001K Heavy-Duty series, it uses K-series compatible contact blocks and a 30.5 mm mounting diameter, with enclosure protection rated at NEMA 4 and 13 for demanding environments. It is rated up to 600 VAC and up to 10 A with the appropriate contact blocks, and the contact configuration requires contact blocks. Connection is via screw terminals (through the contact blocks). This switch supports standard industrial applications such as machine mode selection, process control, and equipment control across manufacturing lines, and is commonly installed to maintain consistent operator control and system functionality during repair, retrofit, or replacement projects. The operating temperature range is -25°C to +70°C. Common replacements include Schneider Electric XB4BD21 Selector Switch, Allen-Bradley 800T-J2 Selector Switch, and Siemens 3SB3500-2EA11 Selector Switch.
