It provides two independent SPDT outputs for dual setpoint or monitoring configurations, with the RD option offering disconnection with manual reset for safety interlock on high-circuit operations. The rugged housing is die-cast aluminum, anodized, and rated IP65 with NEMA 4\/13 compatibility, terminating through a 3\/4\" NPT entry with an internal screw terminal and a 6–12 mm cable gland for straightforward installation. The Gold Line variant (code 251) carries sensor temperature limits of -73°C to +149°C and, like the broader T2H line, supports a wide operating envelope, while offering remote sensing via a remote bulb\/capillary option that can place the sensing element up to 25 feet from the switch. Rated for up to 10 A at 125\/250 VAC (and 3 A at 480 VAC) in typical industrial use, this model is well suited to temperature monitoring and control in industrial equipment and process systems. The part number T2H-H251-A-RD-R5 is the manufacturer’s reference for this configuration, which can be specified with the RD‑Micro switch for manual‑reset disconnection in safety‑critical applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Barksdale","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676673868078,"sku":null,"price":168.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f1474637-ad1e-4139-a5aa-09c2821e7d5e.jpg?v=1769552247","url":"https:\/\/plgautomation.com\/products\/barksdale-t2h-h251-a-rd-r5-temperature-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
