Designed to interrupt fault currents promptly in systems up to 600 V, this part ensures safe operation and swift fault isolation for critical equipment and distribution networks.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent rating\u003c\/strong\u003e: 150 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: 600 V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e: engineered for Square D panels and enclosures that accept HDA-series breakers\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy this 3-pole design matters\u003c\/h3\u003e\n\u003cp\u003eIn three-phase installations, a true three-pole breaker trips all phases together. This coordinated protection prevents imbalanced loads that can stress motors, transformers, and feeders, helping to reduce equipment wear and downtime. The 150 A rating fits feeders and larger branch circuits, offering strong protection without unnecessary interruptions for normal load conditions.\u003c\/p\u003e \u003ch3\u003eIdeal use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eThree-phase motor circuits for pumps, conveyors, and compressors in manufacturing settings\u003c\/li\u003e \u003cli\u003eHVAC equipment and large distributed loads in commercial facilities\u003c\/li\u003e \u003cli\u003ePower distribution feeders within panels and enclosures designed for HDA-series breakers\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eInstallation and practical considerations\u003c\/h3\u003e\n\u003cp\u003eFor safety and reliability, installation should be performed by a qualified electrician in accordance with local electrical codes. Verify panel compatibility with HDA-series breakers, ensure secure electrical connections, and follow standard maintenance practices—checking for signs of overheating, wear, or abnormal tripping behavior during service checks.\u003c\/p\u003e \u003ch3\u003eWhat makes it stand out\u003c\/h3\u003e\n\u003cp\u003eThis breaker combines precise three-pole protection with a 600 V rating, making it a solid choice for higher-voltage, three-phase distribution needs. By choosing a dedicated Square D component within compatible panels, you gain consistent performance, straightforward replacement, and cohesive system operation across your electrical infrastructure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Square D","offers":[{"title":"Default Title","offer_id":46423331405986,"sku":"HDA36150U31XAABCSDYP","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-hda36150u31xaabcsdyp","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
