EH3B030 - 30Amp Circuit Breaker

EH3B030 - 30 Amp Circuit Breaker

The EH3B030 is a 30-amp, 3-pole molded case circuit breaker designed for use in EH3 frame systems. If you're replacing an existing unit, this one lines up with what’s already there—no need to modify your panel or rethink your setup. It handles standard protection for three-phase circuits, with an interrupting rating of 14kA at 480VAC and 18kA at 240VAC. That gives you the coverage needed to deal with overloads and short circuits without putting connected equipment at unnecessary risk. It’s rated for 40°C operation, which fits most typical environments you’ll see in commercial and industrial settings. The construction is straightforward and built to last, which is exactly what you want when you're maintaining older gear that still needs to stay in service.
