It accepts voltage configurations of 208 VAC Star\/120 VAC, 240\/120 VAC Delta (3 Phase 4 Wire), and 240 VAC Delta (3 Phase 3 Wire). The enclosure is NEMA 3R rainproof, making it suitable for outdoor installations. Bus construction uses tin-plated copper for reliable conductivity and corrosion resistance. The main breaker is a bolt-on QDL type with a 25 kiloampere interrupting rating. Licensed electricians install this panel in residential, commercial, and industrial service entrance applications where three-phase power distribution is required.\u003c\/p\u003e\n\u003cp\u003eThis load center is designed for three-phase electrical distribution systems in both indoor and outdoor settings. The convertible main configuration allows top or bottom feed by rotating the panel 180 degrees, giving installers flexibility to adapt to varying job site conduit entry requirements. The split branch neutral design keeps wiring organized and reduces clutter inside the enclosure. Main wire accepts conductors from 4 AWG to 300 KCMIL in both aluminum and copper. The NEMA 3R rating supports exposed outdoor installations where rain protection is needed. This panel is appropriate for light commercial, industrial, and multi-family residential applications requiring 42 circuits of three-phase branch circuit capacity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e225A convertible main breaker with bolt-on QDL breaker mounting and 25 kA interrupting rating\u003c\/li\u003e\n  \u003cli\u003e42 maximum circuit spaces with 3 Phase 3\/4 Wire configuration\u003c\/li\u003e\n  \u003cli\u003eTin-plated copper bus for enhanced conductivity and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eNEMA 3R rainproof enclosure rated for outdoor use\u003c\/li\u003e\n  \u003cli\u003eSplit branch neutral for organized, clutter-free wiring\u003c\/li\u003e\n  \u003cli\u003eTop or bottom feed flexibility via 180-degree panel rotation\u003c\/li\u003e\n  \u003cli\u003eAccepts 4 AWG to 300 KCMIL aluminum or copper main conductors\u003c\/li\u003e\n  \u003cli\u003eUL Listed and NOM approved; manual and automatic transfer switch capable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Square D QO series bolt-on circuit breakers.

Disconnect and lock out all upstream power sources before servicing or wiring this panel. Verify that conductor sizes, breaker ratings, and conduit entries are matched to the supply circuit and load calculations. The NEMA 3R outdoor enclosure requires appropriate weatherproof conduit fittings at all knockouts to maintain the rated enclosure integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 225 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 208 VAC Star\/120 VAC, 240\/120 VAC Delta (3 Phase 4 Wire), 240 VAC Delta (3 Phase 3 Wire)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCircuit Configuration\u003c\/strong\u003e: 3 Phase 3\/4 Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Number of Circuits\u003c\/strong\u003e: 42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Number of Spaces\u003c\/strong\u003e: 42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Breaker Type\u003c\/strong\u003e: QDL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBreaker Mounting\u003c\/strong\u003e: Bolt-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 25 kiloampere\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeutral Type\u003c\/strong\u003e: Split Branch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBus Material\u003c\/strong\u003e: Tin Plated Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMain Wire Size\u003c\/strong\u003e: 4 AWG to 300 KCMIL (Aluminum\/Copper)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Type\u003c\/strong\u003e: NEMA 3R, Rainproof\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Size Designation\u003c\/strong\u003e: 14R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Dimensions\u003c\/strong\u003e: 14.75 inches W x 4.52 inches D x 39.37 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 15.171 inches W x 4.953 inches H x 40.599 inches L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 47.99 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Convertible Main Breaker\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: UL, NOM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: US\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: Schneider Electric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QO342MQ225RB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51284066206002,"sku":"QO342MQ225RB","price":1549.07,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279164.jpg?v=1781067623","url":"https:\/\/voomisupply.com\/products\/schneider-electric-qo342mq225rb-225a-42-space-load-center","provider":"Voomi Supply","version":"1.0","type":"link"}
