Allen-Bradley 101072111 Static Switch Snubber Circuit Board Card

The 101072111 Static Switch Snubber Circuit Board AK is a multi‑layer RC snubber PCB designed to protect semiconductor switching devices from voltage spikes and transient surges in static switching systems. It is used in UPS systems, power supplies, industrial motor drives, and static transfer switches to dampen high‑voltage transients and reduce switching stress on SCRs, IGBTs, thyristors, and other power semiconductors. With chassis mounting and configurable connections (screw terminals or plug‑in connectors, depending on configuration), this board provides durable transient protection in power electronics protection applications. Industry applications include power distribution, UPS systems, industrial automation, and process control, with operating voltage being application dependent and operating temperature in the industrial range. Common replacements include APC Static Switch Snubber Board, Eaton UPS Snubber Circuit Board, Emerson / Vertiv Static Transfer Switch Snubber Assembly.
