With a 90-amp rating and three poles, this unit safeguards every phase in demanding industrial environments, helping machinery run smoothly and reducing the risk of damage from faults or short circuits.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent rating:\u003c\/strong\u003e 90 A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 480 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBrand\/Part number:\u003c\/strong\u003e Square D, IF34090\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy the three-pole design matters: in a 3-phase system,protecting all three lines simultaneously prevents phase imbalances that can stress motors and drives. The IF34090 consolidates three protections into one compact device, ensuring coordinated interruption across all phases when an overcurrent occurs, which translates to safer operation and less downtime.\u003c\/p\u003e \u003cp\u003eIdeal applications include motor feeders, control panels, and distribution panels in manufacturing, processing, and other industrial settings that run on 480 V three-phase power. This breaker is purpose-built for environments where consistent, dependable protection is essential for continuous production and equipment longevity.\u003c\/p\u003e \u003cp\u003ePractical considerations for use: verify that your electrical setup requires a 3-pole, 480 V protection device and that the form factor aligns with your panel or enclosure. The IF34090 is purposefully paired with Square D systems, ensuring straightforward integration in compatible installations and adherence to standard three-phase protection practices.\u003c\/p\u003e \u003cp\u003eCompared with lower-voltage or single-pole alternatives, the Square D IF34090 provides unified protection across all phases in a single unit, streamlining wiring, maintenance, and fault response in demanding industrial circuits.\u003c\/p\u003e \u003cp\u003eProtect critical equipment with a trusted, high-visibility Circuit Breaker that clearly communicates fault conditions across all three phases. The Square D IF34090 90A 3-Pole 480 V Circuit Breaker is ready to help keep your 3-phase systems safe, efficient, and productive.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Square D","offers":[{"title":"Default Title","offer_id":46423105470626,"sku":"IF34090","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/master_generic_229276d9-908d-46df-93e5-6fe31866e0ff.png?v=1765492975","url":"https:\/\/www.ampstate.com\/products\/square-d-if34090","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
