Engineered for reliability in three-phase applications, it ensures safe, simultaneous shutdown of all phases to protect wiring, equipment, and personnel in industrial and commercial environments.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HJA36070SL\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 70 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\u003eBrand:\u003c\/strong\u003e Square D\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy this 3-pole design matters: in a three-phase circuit, a single-pole or two-pole breaker might leave remaining phases energized, increasing risk during a fault. This 3-pole breaker provides coordinated protection by disconnecting all phases, helping prevent damage to motors, drives, and other three-phase equipment.\u003c\/p\u003e \u003cp\u003eIdeal use cases include industrial motor drives, conveyors, pumps, and other three-phase loads in panelboards and commercial electrical rooms. The HJA36070SL is a compatible replacement option within the Square D lineup, offering consistent performance for maintenance-ready electrical systems and minimizing downtime when service or replacement is needed.\u003c\/p\u003e \u003cp\u003eInstallation and compatibility notes: verify that your panel labeling confirms compatibility with HJA36070SL, and ensure the bus type matches your Square D panel. Adhere to standard electrical safety practices during replacement or installation, and maintain a small stock of this common 70 A, 3-pole unit for quick emergency downtime recovery.\u003c\/p\u003e \u003cp\u003eWith the Square D HJA36070SL, you gain a trusted, robust solution for protecting 600 V three-phase circuits, delivering reliable interruption when faults occur and contributing to safer, more efficient operation of industrial and commercial electrical systems.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Square D","offers":[{"title":"Default Title","offer_id":46423566745762,"sku":"HJA36070SL","price":3552.0,"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-hja36070sl","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
