With a 31 A rating, a 3-pole configuration, and a 600 V maximum, this device is designed to protect demanding loads while ensuring safe, automatic shutdown during overloads.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eCurrent rating:\u003c\/strong\u003e 31 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\u003ePart number:\u003c\/strong\u003e PKA36080U31A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBrand\/series:\u003c\/strong\u003e Square D PK A family compatible device\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy this 3-pole design matters\u003c\/h3\u003e\n\u003cp\u003eThree-pole protection means all three phases are disconnected together in an overload or fault condition. This coordinated shutdown reduces the risk of arc flash, protects conductors and motors, and helps maintain safe operation of 3-phase equipment in industrial and commercial environments. The PK A-style form factor is chosen for reliable mounting and consistent trip characteristics in panels that require a three-phase, 600 V distribution solution.\u003c\/p\u003e \u003ch3\u003eIdeal applications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eIndustrial motor circuits and three-phase equipment up to 31 A\u003c\/li\u003e \u003cli\u003eCommercial distribution panels where three-phase protection is essential\u003c\/li\u003e \u003cli\u003eReplacement or upgrades for compatible Square D PK A-series panels and assemblies\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eInstallation and compatibility tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eEnsure panel compatibility with 3-pole, 600 V breakers in the Square D PK A family.\u003c\/li\u003e \u003cli\u003eVerify conductor sizing and enclosure clearance align with a 31 A, 3-pole device.\u003c\/li\u003e \u003cli\u003eFollow the manufacturer's installation instructions for mounting and terminal torque to ensure reliable performance.\u003c\/li\u003e \u003cli\u003eUse in circuits where simultaneous disconnection of all three phases is required for safe operation of motors and three-phase loads.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eFor professionals seeking dependable, category-appropriate protection in three-phase systems, the Square D PKA36080U31A delivers precise protection with a straightforward, compatible design that slots into existing PK A-series panels and distributions, ensuring consistent performance across demanding applications.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Square D","offers":[{"title":"Default Title","offer_id":46423050584226,"sku":"PKA36080U31A","price":53094.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/square-d-pka36080u31a-31a-3-pole-600-v-circuit-breaker-956.webp?v=1789264618","url":"https:\/\/www.ampstate.com\/products\/square-d-pka36080u31a","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
