EHB34070 - 70 Amp Circuit Breaker

EHB34070 - 70 Amp Circuit Breaker

When you’re dealing with an existing panel and need a breaker that actually fits without headaches, the EHB34070 is a straightforward solution. This 3-pole, 70-amp breaker is built for EHB-4 frame panelboards, so it lines up with what’s already in place—no modifications, no second-guessing. It’s a bolt-on style, which means it mounts securely and stays put. That matters in real-world applications where vibration, load demands, and daily use come into play. With interrupting ratings of 14k AIC at 480VAC and 65k AIC at 240VAC, it’s designed to handle fault conditions while keeping your system protected and consistent with its original design. If you're maintaining or repairing a commercial or industrial setup, this breaker helps keep things running the way they were intended—simple as that.
