With a 100 A rating, 3 poles, and a 600 V maximum voltage, this unit is designed to reliably interrupt fault current and isolate circuits to keep equipment safe.\u003c\/p\u003e \u003cul\u003e \u003cli\u003ePart Number: HRA36100U31XAABCSJ\u003c\/li\u003e \u003cli\u003eCurrent rating: 100 A\u003c\/li\u003e \u003cli\u003ePoles: 3\u003c\/li\u003e \u003cli\u003eVoltage rating: 600 V\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy this configuration matters: In three-phase systems, a 3-pole breaker ensures all phases trip together, preventing unbalanced faults from causing overheating or damage to motors, drives, and other equipment. The 100 A rating is ideal for mid‑sized feeders and branch circuits that require solid protection without sacrificing performance.\u003c\/p\u003e \u003cp\u003eIdeal use scenarios\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eThree-phase distribution panels in industrial facilities powered by up to 600 V systems\u003c\/li\u003e \u003cli\u003eCommercial buildings with medium-current feeders that demand precise protection at 100 A\u003c\/li\u003e \u003cli\u003eReplacement or retrofit in existing Square D installations to maintain compatibility and system integrity\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy choose this specific model: The HRA36100U31XAABCSJ is a direct-fit solution for panels and applications designed around Square D’s HRA-style, 3-pole, 600 V circuit breakers. Its exact configuration simplifies selection, reduces compatibility risk, and supports consistent protection across your electrical infrastructure. As a trusted Square D device, it pairs with decades of protection engineering to deliver reliable performance in everyday operations and during fault events.\u003c\/p\u003e \u003cp\u003ePractical considerations and insights\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eConfirm panel compatibility: this part number is formulated for Square D installations requiring a 3-pole, 100 A device for 600 V circuits.\u003c\/li\u003e \u003cli\u003eUse case alignment: ideal for mid-range feeders and critical three-phase loads where reliable tripping behavior is essential.\u003c\/li\u003e \u003cli\u003eMaintenance mindset: keep spare units of the same configuration on hand to minimize downtime during replacements or panel upgrades.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Square D","offers":[{"title":"Default Title","offer_id":46423284252834,"sku":"HRA36100U31XAABCSJ","price":510.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/square-d-hra36100u31xaabcsj-100a-3-pole-600-v-circuit-breaker-286.webp?v=1789291808","url":"https:\/\/www.ampstate.com\/products\/square-d-hra36100u31xaabcsj","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
