Built by Square D, it pairs rugged construction with precise thermal-magnetic protection to keep critical circuits safe in busy commercial spaces and homes.\u003c\/p\u003e \u003ch3\u003eSmart design for reliable, vibration-prone installations\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eBolt-on mounting\u003c\/strong\u003e provides a rigid, vibration-resistant bus connection that stays tight even in environments with equipment vibration or temperature fluctuations.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eThermal-magnetic trip unit\u003c\/strong\u003e combines heat and magnetic sensing to deliver stable, repeatable protection, reducing nuisance trips while responding rapidly to short circuits.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003e2-pole, 60A, 240V\u003c\/strong\u003e rating is suitable for standard 240V branch circuits, including multi-wire setups when paired with the correct bus and enclosure.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOEM compatibility\u003c\/strong\u003e designed to pair with matching Square D load centers and panelboards for straightforward, plug-and-play installation.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVersatile applications\u003c\/strong\u003e ideal for residential, commercial, and light industrial panels where reliable protection is essential.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhy this matters: in electrical distribution, a breaker’s role is to interrupt current before wiring, devices, and people are endangered. The QOB260’s thermal-magnetic technology means that overloads (like a miswired load or a fault) trigger the trip predictably, while a parallel short-circuit draws a high magnetic force that snaps open the circuit within milliseconds. That combination minimizes downtime and protects transformers, feeders, and sensitive equipment.\u003c\/p\u003e \u003ch3\u003ePractical use cases\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eNew installations in panelboards and load centers that require a robust bolt-on solution.\u003c\/li\u003e \u003cli\u003eUpgrades or replacements in residential service panels and light commercial distribution boards.\u003c\/li\u003e \u003cli\u003eSpare-part stocking for field service teams maintaining Square D systems.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eTechnical snapshot\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eManufacturer: Square D\u003c\/li\u003e \u003cli\u003ePart Number: QOB260\u003c\/li\u003e \u003cli\u003eType: Thermal-magnetic molded case circuit breaker\u003c\/li\u003e \u003cli\u003eAmperage Rating: 60A\u003c\/li\u003e \u003cli\u003eVoltage Rating: 240V\u003c\/li\u003e \u003cli\u003eNumber of Poles: 2\u003c\/li\u003e \u003cli\u003eMounting Style: Bolt-on\u003c\/li\u003e \u003cli\u003eApplication: Branch circuit overcurrent and short-circuit protection\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWho should buy this: electricians, facilities managers, and maintenance technicians stocking reliable, OEM-aligned protection for Square D panelboards and load centers. If you’re upgrading from a non-bolt-on solution or expanding a 240V distribution, the QOB260 delivers predictable protection with a familiar mounting approach and seamless compatibility.\u003c\/p\u003e \u003cp\u003eNotes for installation: always shut off power and follow local electrical codes. Use the QOB260 only in compatible Square D panelboards and load centers. Ensure correct torque and mounting procedures per the manufacturer’s instructions to maintain fault current protection and warranty compliance.\u003c\/p\u003e \u003cp\u003eWith the Square D QOB260, you get a dedicated, dependable bolt-on breaker that protects your 240V circuits with a precise thermal-magnetic trip, a stable bus connection, and OEM-aligned compatibility — a practical choice for reliable electrical distribution in any modern building.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46355413106850,"sku":null,"price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/schnieder_and_square_d_breaker_and_panel_bbb1115a-82d3-40d3-8bb4-ba02c17b540a.png?v=1764691954","url":"https:\/\/www.ampstate.com\/products\/square-d-qob260-60a-240v-2-pole-bolt-on-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
