It is designed for installation in compatible load centers and provides overcurrent protection for branch circuits in residential and light commercial electrical systems. The THQL2140 features a quick-make\/quick-break mechanism for consistent switching action and common trip bars to ensure both poles open simultaneously under fault conditions. A clearly visible trip indication makes it easy to identify a tripped breaker during troubleshooting. Licensed electricians install this breaker as part of panel work covered under NEC guidelines.\u003c\/p\u003e\n\u003cp\u003eThis breaker is suited for residential and light commercial load centers where a 40-amp, 2-pole branch circuit is required. Typical applications include 240-volt circuits for electric dryers, HVAC equipment, water heaters, and similar double-pole loads. The plug-in mounting style allows straightforward installation into compatible load center bus configurations. Wire size compatibility ranges from 8 AWG to 3 AWG, accommodating standard branch circuit conductors used in these applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-amp, 2-pole configuration for 120\/240 volt AC double-pole branch circuits\u003c\/li\u003e\n  \u003cli\u003e10 kiloamp interrupting rating for fault current protection\u003c\/li\u003e\n  \u003cli\u003eQuick-make\/quick-break mechanism for reliable switching action\u003c\/li\u003e\n  \u003cli\u003eCommon trip bars ensure simultaneous pole opening on both phases\u003c\/li\u003e\n  \u003cli\u003eVisible trip indication simplifies fault identification during inspection\u003c\/li\u003e\n  \u003cli\u003eUL listed for use in Canada and the United States\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a plug-in, non-interchangeable circuit breaker for compatible load centers accepting the THQL breaker series.
