EHB34030 - 30 Amp Circuit Breaker

EHB34030 - 30 Amp Circuit Breaker

If you’ve ever had to track down the exact breaker your panel was built for, you know how important the details are. The EHB34030 bolt-on circuit breaker takes the guesswork out of the process. Designed for EHB-4 frame panelboards, this 3-pole, 30-amp breaker fits right into place and does exactly what it’s supposed to—protect your system from overloads and short circuits without creating compatibility headaches. The bolt-on mounting style gives you a secure, fixed connection to the panel, which is especially important in commercial and industrial environments where stability matters. With interrupting ratings of 14k A.I.C. at 480VAC and 65k A.I.C. at 240VAC, it’s built to handle fault conditions within its intended range. It’s a straightforward, dependable solution for keeping existing electrical systems operating safely and efficiently.
