It provides overcurrent and short-circuit protection in panelboards and load centers that accept bolt-on style breakers. The QOB31001021 accepts wire sizes from 4 AWG through 2\/0 AWG via box lug terminals, making it well-suited for feeder and branch circuit applications that require a higher-ampacity 3-pole device. Licensed electricians install this breaker as part of new construction wiring, panel upgrades, or direct replacement of failed breakers in compatible bolt-on enclosures. It carries UL Listed, CSA, and RoHS compliance certifications.\u003c\/p\u003e\n\u003cp\u003eThis circuit breaker is intended for use in bolt-on style panelboards and load centers. The shunt trip accessory compatibility supports remote trip applications requiring 120, 208, or 240 VAC shunt trip coils. At 100 amps and 3 poles, it is commonly used to protect three-phase or multi-wire branch circuits in commercial and light-industrial settings, as well as large residential feeder applications. The box lug terminal design accommodates aluminum or copper conductors in the 4 AWG to 2\/0 AWG range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-amp continuous current rating at 240 VAC\u003c\/li\u003e\n  \u003cli\u003e3-pole configuration for three-phase or multi-wire circuit protection\u003c\/li\u003e\n  \u003cli\u003eBolt-on mount type for secure, vibration-resistant installation in compatible panelboards\u003c\/li\u003e\n  \u003cli\u003eBox lug terminals accept 4 AWG through 2\/0 AWG conductors\u003c\/li\u003e\n  \u003cli\u003eCompatible with shunt trip accessories rated 120, 208, or 240 VAC for remote trip functionality\u003c\/li\u003e\n  \u003cli\u003eUL Listed, CSA certified, and RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with bolt-on style panelboards and load centers that accept QOB-series miniature circuit breakers.

De-energize and lock out the panelboard before removing or installing any circuit breaker. Verify that conductor size falls within the 4 AWG to 2\/0 AWG rating of the box lug terminals before terminating. Do not exceed the breaker's rated ampacity or install in a non-bolt-on enclosure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 100 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 240 VAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 4 to 2\/0 AWG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Connection Type\u003c\/strong\u003e: Box Lugs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Bolt-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.35 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed, CSA, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QOB31001021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541314666802,"sku":"QOB31001021","price":749.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f57e691e41b2e4927d56f0a96005d3d8.jpg?v=1785872174","url":"https:\/\/voomisupply.com\/products\/square-d-qob31001021-bolt-on-circuit-breaker-100a-3p","provider":"Voomi Supply","version":"1.0","type":"link"}
