The unit is specified for a shaft speed range of 1,850 to 2,300 RPM, positioning it for use in governor-driven systems and other machinery where precise overspeed protection is critical. As part of the Synchro-Start line, the SA-503-A provides a robust, relayed output intended to interface with safety interlocks, alarms, or control circuitry in industrial equipment. The switch is built to withstand demanding industrial environments and to deliver repeatable performance in protecting engines and turbines from overspeed conditions. Common applications include engine-generator sets, industrial turbines, pumps, and other rotating machinery where reliable overspeed detection helps prevent mechanical damage and enhances operator safety.\u003c\/p\u003e\u003c\/div\u003e","brand":"SYNCHRO-START","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46253349568746,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-010.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-sa-503-a-overspeed-control-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
