ED63B110 - 110Amp Circuit Breaker

ED63B110 - 110 Amp Circuit Breaker

The ED63B110 is a 110-amp, 3-pole breaker built for straightforward, dependable circuit protection in commercial and industrial setups. It’s part of the ED6 frame series and uses a bolt-on design, so once it’s in place, it stays put—no fussing with loose connections. This unit handles a wide range of fault conditions with solid interrupting ratings across 240V, 480V, and 600V systems. It also comes with load-side terminals already included, which saves a step during install. If you're working in HVAC or similar environments, the HACR rating makes it a safe bet. Another plus—it's suitable for reverse feed, which gives you a bit more flexibility depending on how your panel is set up.
