Auxiliary contact blocks extend the switching capability of a contactor by providing additional normally open or normally closed contacts for control circuit logic, interlocking, and status signaling. This unit is installed by licensed electricians and electrical maintenance technicians working on motor control centers, panel boards, and control cabinets where reliable auxiliary switching is required.\u003c\/p\u003e\n\u003cp\u003eThe CR305X100B is suited for industrial control applications where supplemental contacts are needed alongside primary contactor operation. Typical installations include motor control circuits in commercial HVAC systems, pump controls, conveyor systems, and other motor-driven equipment requiring control logic feedback or interlock wiring. It is intended as a direct add-on block that mounts to compatible ABB contactor and starter frames.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBasic auxiliary contact block configuration for add-on mounting to compatible contactors\u003c\/li\u003e\n  \u003cli\u003eExtends control circuit switching without adding a separate relay\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 3.5 inches long, 2.5 inches wide, and 1.0 inch tall\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.23 pounds for easy handling during panel assembly\u003c\/li\u003e\n  \u003cli\u003eSuitable for control circuit interlocking and status signaling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style add-on auxiliary contact block for compatible ABB motor starter and contactor assemblies.

De-energize and lock out the control panel before installing or removing auxiliary contact blocks. Confirm that the block is fully seated and mechanically secured to the contactor before restoring power. Do not exceed the contact rating of the auxiliary block when wiring control circuits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 78316635212\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: CR305X100B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51383763304754,"sku":"CR305X100B","price":157.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678059.jpg?v=1782606694","url":"https:\/\/voomisupply.com\/products\/abb-cr305x100b-auxiliary-contact-block-basic","provider":"Voomi Supply","version":"1.0","type":"link"}
