EH34020 - 20 Amp Circuit Breaker

EH34020 - 20 Amp Circuit Breaker

The EH34020 is a 3-pole, 20-amp circuit breaker made for EH-4 frame panelboards. If you’re replacing an existing breaker and need something that lines up properly without forcing it, this is built for that exact situation. No guesswork on fit—just install it where it belongs and move on. It uses a thermal magnetic trip, so it handles both overloads and short circuits the way you’d expect. Nothing fancy, just the kind of protection that’s been used for years in commercial and industrial panels. The plug-on design keeps things simple during installation, especially when you’re working in a tight panel and don’t want to waste time. On the rating side, you’re looking at 14kA at 480VAC and 65kA at 240VAC. That makes it a solid match for a wide range of three-phase setups—lighting, small equipment, distribution circuits—typical stuff you see every day. This is really about keeping your existing system going. Same footprint, same function, no surprises.
