It uses an external bellows actuator constructed from copper alloy and stainless steel Type 316, and is designed for water, air, and oil media. The unit operates from a 600 V supply, with a cable-screw gland electrical connection and a standard Trip\/Reset configuration; the contact block is normally open, single-pole, with HP-rated load capacity (0.5 HP at 115 V AC \/ 1 HP at 230 V AC) and control-circuit ratings that vary by voltage. The enclosure is a Type 4 \u0026amp; 13 metallic aluminum design, providing robust protection in harsh environments, and the device features an ingress rating suitable for industrial service. Pressure connections are specified as 1\/4 in NPTF internal pipe thread or 3\/8 in NPSF internal pipe connection (836-C1 and 836-C1A only), so verify porting for this exact model. Its compact footprint measures 96.8 mm wide by 92.9 mm deep by 234.24 mm high and it weighs approximately 5 lb when shipped. Operating temperature is listed as -22 °F with the same storage temperature, aligning with installations in cooler environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657435480366,"sku":null,"price":493.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_04173d0d-aab7-46ab-b4fa-5e99b976736e.jpg?v=1769468944","url":"https:\/\/plgautomation.com\/products\/allen-bradley-836-c7jx221-pressure-control-device","provider":"PLG Automation ","version":"1.0","type":"link"}
