It provides overcurrent and short-circuit protection for branch circuits and equipment loads in residential and light commercial electrical panels. The QOU2125 accepts wire sizes from 12 AWG to 2\/0 AWG via box lug terminals, making it suitable for high-amperage branch circuits feeding large loads. It mounts directly to a compatible panelboard. Licensed electricians install this breaker as part of service panel work governed by the National Electrical Code (NEC). CSA, UL, IEC, and RoHS compliance confirms it meets widely accepted North American and international standards.\u003c\/p\u003e\u003cp\u003eThe QOU2125 is rated for use with air conditioning and refrigeration equipment as well as heating systems, making it a common choice for HVAC disconnect and subpanel branch circuit protection. Its 125-amp rating and 2-pole configuration allow it to serve 240-volt double-pole loads including condensing units, electric furnaces, heat pumps, and similar equipment. Panel mount installation allows direct integration into compatible Square D QO and compatible panelboards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e125-amp overcurrent protection at 240 volts AC\u003c\/li\u003e\n\u003cli\u003e2-pole configuration for double-pole 240-volt branch circuits\u003c\/li\u003e\n\u003cli\u003eBox lug terminal connection accepts 12 AWG to 2\/0 AWG wire\u003c\/li\u003e\n\u003cli\u003ePanel mount design for direct panelboard installation\u003c\/li\u003e\n\u003cli\u003eRated for air conditioning, refrigeration, and heating equipment loads\u003c\/li\u003e\n\u003cli\u003eUL Listed, CSA certified, IEC compliant, and RoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with air conditioning and refrigeration equipment and heating systems as stated by the manufacturer.
