It provides overcurrent and short-circuit protection for 120\/240-volt AC branch circuits in residential and light commercial electrical systems. The common-trip design ensures both poles open simultaneously under fault conditions. With a 10-kiloamp interrupting rating and UL 489 listing, this breaker meets standard requirements for load center installations. Licensed electricians install this breaker as part of panel upgrades, new construction wiring, or branch circuit additions.\u003c\/p\u003e\u003cp\u003eThe CHF240 is suited for residential and light commercial applications where a 2-pole, 40-amp breaker is required for circuits such as electric ranges, dryers, HVAC equipment, and similar double-pole loads. Its plug-on mounting style allows for straightforward installation in compatible CH Series load centers without the need for additional hardware. The breaker accepts copper or aluminum conductors ranging from 10 AWG to 1\/0 AWG, providing flexibility for various wiring configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e40-amp current rating for double-pole branch circuit protection\u003c\/li\u003e\n\u003cli\u003eCommon-trip mechanism opens both poles simultaneously under fault conditions\u003c\/li\u003e\n\u003cli\u003ePlug-on mounting for direct installation in CH Series load centers\u003c\/li\u003e\n\u003cli\u003e10-kiloamp interrupting rating for fault current protection\u003c\/li\u003e\n\u003cli\u003eAccepts 10 AWG to 1\/0 AWG copper or aluminum conductors\u003c\/li\u003e\n\u003cli\u003eUL 489 listed for compliance with standard circuit breaker requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CH Series load centers as specified by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the load center and verify the panel is fully de-energized before handling or installing the breaker. Ensure conductor size and type are within the rated wire range before terminating. Do not exceed the breaker's rated ampacity or interrupting capacity for the intended circuit application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 40 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 120\/240 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating\u003c\/strong\u003e: 10 kiloamps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Type\u003c\/strong\u003e: Common Trip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Plug-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 10 to 1\/0 AWG (Copper\/Aluminum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproval\u003c\/strong\u003e: UL 489\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: CHF240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SQUARE D","offers":[{"title":"Default Title","offer_id":51283949814066,"sku":"CHF240","price":53.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278321.jpg?v=1781063971","url":"https:\/\/voomisupply.com\/products\/square-d-chf240-2-pole-40-amp-circuit-breaker-ch-series","provider":"Voomi Supply","version":"1.0","type":"link"}
