Auxiliary switches provide electrical status feedback from the main contactor, allowing control circuits to monitor whether a starter is open or closed. The THAUX21D mounts directly to the contactor body and wires into the low-voltage control circuit. It is a standard accessory installed by licensed electricians and industrial maintenance technicians working on motor control centers and panel boards.\u003c\/p\u003e\n\u003cp\u003eThe THAUX21D is suited for commercial and industrial applications where status indication, interlocking, or control sequencing is required. Typical installations include motor control centers, machine control panels, and HVAC equipment starter assemblies. The DPDT configuration provides two sets of normally open and normally closed contacts, supporting multiple control circuit functions from a single auxiliary switch body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDPDT contact configuration provides both normally open and normally closed outputs\u003c\/li\u003e\n  \u003cli\u003eDirect-mount design attaches to the contactor body without separate hardware\u003c\/li\u003e\n  \u003cli\u003eSupports status indication and interlocking in low-voltage control circuits\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for panel and motor control center installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style auxiliary switch accessory for compatible ABB contactors and motor starters.

De-energize and lock out the contactor and all associated control circuits before attaching or removing the auxiliary switch. Verify contact ratings are appropriate for the control circuit voltage and current before wiring. Do not exceed the rated switching capacity of the auxiliary contacts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: DPDT (Double-Pole Double-Throw)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316416128\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ABB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: THAUX21D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383571087666,"sku":"THAUX21D","price":160.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312676798.jpg?v=1782600881","url":"https:\/\/voomisupply.com\/products\/abb-thaux21d-auxiliary-switch-dpdt","provider":"Voomi Supply","version":"1.0","type":"link"}
