It is a terminal-block type undervoltage release that integrates directly into the breaker and is designed for left-hand mounting. Built for 50\/60 Hz AC systems, it provides consistent tripping performance when voltage falls below the required threshold. This component is commonly used in industrial and commercial power distribution systems to prevent unsafe operation during undervoltage conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong data-end=\"1102\" data-start=\"1085\"\u003eKey Features:\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1151\" data-end=\"1929\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1030\" data-end=\"1728\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1074\" data-end=\"1750\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1028\" data-end=\"1649\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1052\" data-end=\"1655\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1025\" data-end=\"1671\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1035\" data-end=\"1725\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1080\" data-end=\"1765\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1048\" data-end=\"1709\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1013\" data-end=\"1635\"\u003e\u003c\/ul\u003e\n\u003cul data-end=\"1631\" data-start=\"1022\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1053\" data-end=\"1644\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1051\" data-end=\"1648\"\u003e\u003c\/ul\u003e\n\u003cul data-end=\"1673\" data-start=\"1008\"\u003e\u003c\/ul\u003e\n\u003cul data-end=\"1779\" data-start=\"1091\"\u003e\u003c\/ul\u003e\n\u003cul data-end=\"1736\" data-start=\"1077\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1134\" data-end=\"1862\"\u003e\u003c\/ul\u003e\n\u003cul data-start=\"1065\" data-end=\"1718\"\u003e\n\u003cli data-section-id=\"17g5yez\" data-start=\"1065\" data-end=\"1169\"\u003eUndervoltage Protection: Automatically trips the breaker when supply voltage drops below safe levels\u003c\/li\u003e\n\u003cli data-section-id=\"j0m32r\" data-start=\"1170\" data-end=\"1248\"\u003eRated Voltage Range: Operates at 110–127V AC for standard control circuits\u003c\/li\u003e\n\u003cli data-section-id=\"g98szv\" data-start=\"1249\" data-end=\"1315\"\u003eFrequency Compatibility: Supports both 50 Hz and 60 Hz systems\u003c\/li\u003e\n\u003cli data-section-id=\"9hmqi9\" data-start=\"1316\" data-end=\"1398\"\u003e3VF Series Integration: Designed for Siemens 3VF3 molded case circuit breakers\u003c\/li\u003e\n\u003cli data-section-id=\"1qi1t5j\" data-start=\"1399\" data-end=\"1487\"\u003eLeft-Side Mounting: Configured for installation on the left-hand side of the breaker\u003c\/li\u003e\n\u003cli data-section-id=\"zsfssk\" data-start=\"1488\" data-end=\"1564\"\u003eTerminal Block Connection: Provides secure and reliable wiring interface\u003c\/li\u003e\n\u003cli data-section-id=\"oybv2\" data-start=\"1565\" data-end=\"1641\"\u003eReliable Tripping Mechanism: Ensures consistent response to voltage loss\u003c\/li\u003e\n\u003cli data-section-id=\"1jzb49y\" data-start=\"1642\" data-end=\"1718\"\u003eRetrofit Capability: Suitable for breakers manufactured from 1997 onward\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"1720\" data-end=\"1863\"\u003eThe 3VF9321-1CG10 delivers the reliability and precision required for voltage monitoring and protection in molded case circuit breaker systems.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":51351776198954,"sku":"3VF9321-1CG10","price":784.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/iqelectro_photo2_e9cab27a-fa4b-4317-a876-a5872d9eb64e.png?v=1775037436","url":"https:\/\/iqelectro.com\/products\/siemens-3vf9321-1cg10-undervoltage-release-110-127v-ac-left-mount-for-3vf3-circuit-breakers","provider":"IQElectro","version":"1.0","type":"link"}
