Square D EDB24080 2 Pole 80 Amp 480V 277V Circuit Breaker

The Square D by Schneider Electric EDB24080 is a two-pole, 80-amp molded-case circuit breaker in the E-Frame family, designed for bolt-on installation in 480Y/277 VAC electrical distributions and panelboards used in commercial and industrial facilities. It employs a thermal-magnetic trip mechanism tuned for 480Y/277 VAC systems and provides an 18 kA interrupting rating at 480Y/277 VAC; for 240 VAC operation, a 25 kA rating is also specified in data sheets, and the lugs accept aluminum or copper conductors from 14 AWG to 2/0 AWG. This bolt-on, two-pole breaker is designed for use in Square D panelboards and other NF panelboard installations, delivering reliable protection for 480/277 V feeders in light-industrial and commercial electrical distributions, with a compact 2-inch-wide mounting footprint typical of E-frame devices. As part of the EDB E-Frame, the EDB24080 is a standard-distribution protective device in 80 A, 2P configurations that integrates with Schneider Electric's Square D product family for consistent compatibility.
