Its 3-phase input line voltage ensures consistent performance on 50 or 60 Hz systems. The controller's 251 A rating and 200 Hp @ 460V AC output make it a strong match for medium-horsepower motor installations. Because the unit includes electronic motor overload protection, it provides an integrated control and protection solution during an upgrade.\u003c\/p\u003e\u003ch2\u003eRetrofit \u0026amp; Installation Guidance\u003c\/h2\u003e\u003cp\u003eWhen replacing an older motor starter with the Allen-Bradley 150-F251NCD, verify the line voltage matches the 200-575V AC, 3-phase input rating. Confirm the motor's rated current does not exceed the 251 A controller rating. The open enclosure requires clean, dry cabinet space with adequate air circulation. Mount the unit securely and check that the control voltage is within 100-240V AC for units rated 5-480 A. The rated voltage of 500\/575V AC should match the motor and applied line system. During installation, keep the 14.54 kg weight in mind and use proper lifting procedures.\u003c\/p\u003e\u003ch2\u003eSelection \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering the 150-F251NCD, check your motor full-load current and supply voltage. The 251 A rating and 200-575V AC input are the primary selection criteria. If your system operates at 500 or 575V AC, the rated voltage of this controller aligns with those voltage classes. For sourcing genuine industrial automation spares, PLC Source PRO lists the Allen-Bradley 150-F251NCD alongside other drives and control system parts. Confirm your application requirements before purchase to ensure the controller matches the motor and enclosure configuration.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default","offer_id":44433734893667,"sku":"150-F251NCD","price":210.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/150-F251NZD.jpg?v=1785730255","url":"https:\/\/www.plcsourcepro.com\/ar\/products\/allen-bradley-150-f251ncd-smc-flex-industrial-automation-module","provider":"PLC Source PRO","version":"1.0","type":"link"}
