EH1B030 - 30Amp Circuit Breaker

EH1B030 - 30 Amp Circuit Breaker

If you’re maintaining or restoring an existing electrical system built around the EH1 frame, the EH1B030 circuit breaker gives you exactly what you need—no modifications, no uncertainty. This 30-amp, single-pole molded case circuit breaker is designed to match the original form, fit, and function of EH1 configurations, making it a straightforward replacement for keeping your system running as intended.

It handles everyday protection demands with a 14kA interrupting capacity at 277VAC, helping manage overloads and short circuits in branch circuits without complicating your setup. Built for standard 40°C environments, it’s suited for real-world conditions you’ll find in commercial facilities and industrial panels. The construction is simple and durable—these breakers are built to last—so you can install with confidence and move on to the next job.

Where It Works Best

• The EH1B030 is a practical choice for commercial buildings, industrial facilities, and maintenance environments where EH1 frame breakers are already in place. You’ll typically find it used in lighting panels, branch circuit protection, and equipment-level applications that call for a 30-amp, single-pole configuration. It’s especially useful when keeping older systems operational without redesigning the panel or replacing existing infrastructure.
