It features 3\/8 in FNPT ports, two‑pole snap‑action contacts in a DPST arrangement, UL listed and CSA certified construction, and a NEMA 1 enclosure (with optional NEMA 3R\/4 enclosures available through some distributors); the design includes a two‑way pressure relief valve (unloader) that vents head pressure at cut‑off to ease shut‑down and reduce stress on the system, and the device is diaphragm actuated and rated for 50\/60 Hz operation. Typical applications include regulating tank pressure on small air compressors up to roughly 300 psi and supporting standard 3\/8\" FNPT fittings with control voltages up to 600 VAC or 125–600 VDC, depending on the specific variant and installation. \u003c\/p\u003e\u003c\/div\u003e","brand":"SQUARE","offers":[{"title":"New","offer_id":46253933887722,"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-011.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-9013ghg-3j57x-pressure-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
