It uses a 7\/16\"-20 UNF female connection with a Schrader depressor and snubber for direct mounting or integration with standard accessories. The W6S variant provides a fixed setpoint pair of 16.0 bar (cut‑in) and 21.0 bar (cut‑out), supports a maximum operating pressure up to 45 bar, and withstands a test pressure of 50 bar, with an ambient rating up to +70°C. This model is commonly applied for condenser and compressor protection in industrial refrigeration and air‑conditioning systems, and its auto‑reset configuration (W type) enables automatic recovery after a fault without manual intervention.\u003c\/p\u003e\u003c\/div\u003e","brand":"Alco","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657190900014,"sku":null,"price":240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e292dc9d-7bbb-444b-ba70-9f620f5b712d.jpg?v=1769466713","url":"https:\/\/plgautomation.com\/products\/alco-controls-ps3-w6s-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
