With a 10 kiloamp interrupting rating and UL 489 listing, this breaker provides reliable overcurrent protection in residential and light commercial panelboards. The plug-on mounting style allows for straightforward installation without additional hardware. Electricians and panel technicians use this breaker as a direct-fit addition or replacement in compatible load center enclosures. It accepts copper or aluminum conductors in the appropriate wire size ranges for the application.\u003c\/p\u003e\u003cp\u003eThe CH120 is suited for branch circuit protection in residential services and light commercial electrical systems. It installs in CH Series Square D load centers where single-pole, 20-amp protection is required for general-purpose circuits such as lighting, receptacles, and small appliance loads. Its compact form factor fits standard panel configurations without requiring derating adjacent slots. Electricians working on service upgrades, panel additions, or breaker replacements will find this a straightforward drop-in solution within compatible enclosures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e20-amp current rating for standard branch circuit protection\u003c\/li\u003e\n\u003cli\u003eSingle-pole, 120\/240 volt AC rating\u003c\/li\u003e\n\u003cli\u003e10 kiloamp interrupting rating for fault current protection\u003c\/li\u003e\n\u003cli\u003ePlug-on mounting for tool-free bus connection\u003c\/li\u003e\n\u003cli\u003eAccepts copper or aluminum conductors: one conductor 14 to 8 AWG or two conductors 14 to 10 AWG\u003c\/li\u003e\n\u003cli\u003eUL 489 listed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CH Series Square D 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 all applicable local codes.
