Rated at 600 volts AC and 10 amps, it uses a knob-style actuator in a 30 mm body with a black and white finish. An OFF-ON nameplate is included. This switch is installed in industrial and commercial control panels to select between two operating states, making it a standard component for machine control, motor starters, and process equipment wiring. Licensed electricians and panel builders are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThe cr104psg21b91a fits 30 mm panel cutouts and is suited for use in industrial control enclosures, motor control centers, and commercial electrical panels. The maintained-action mechanism holds its selected position after the operator releases the knob, which distinguishes it from momentary-style switches. The included 1NO\/1NC contact configuration supports a wide range of two-state control circuits common in manufacturing and facility automation environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintained 2-position knob actuator holds selected position without operator input\u003c\/li\u003e\n  \u003cli\u003e1 normally open and 1 normally closed contact block included in kit\u003c\/li\u003e\n  \u003cli\u003eRated 600 volts AC and 10 amps for robust industrial circuit use\u003c\/li\u003e\n  \u003cli\u003e30 mm body size fits standard industrial panel cutouts\u003c\/li\u003e\n  \u003cli\u003eOFF-ON nameplate included for clear operator identification\u003c\/li\u003e\n  \u003cli\u003eBlack and white color scheme for visual contrast on panel faces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation selector switch for 30 mm industrial control panel assemblies within the CR104 product family.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed electrician in accordance with NEC requirements for control circuit wiring. De-energize and lock out the panel before mounting or wiring the switch. Verify the panel cutout diameter matches the 30 mm body before installation. Confirm contact block wiring matches the intended circuit logic before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage (AC)\u003c\/strong\u003e: 600 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 10 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Knob\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePositions\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAction\u003c\/strong\u003e: Maintained\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: 1NO\/1NC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black and White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFamily\u003c\/strong\u003e: CR104\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: cr104psg21b91a\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":51672803508530,"sku":"CR104PSG21B91A","price":84.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ea6a37321acbff5fab13b119b887be7.jpg?v=1787973198","url":"https:\/\/voomisupply.com\/products\/abb-cr104psg21b91a-selector-switch-2-position-30mm-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
