EHB2070 - 70Amp Circuit Breaker

EHB2070 - 70 Amp Circuit Breaker

If you're working on an older panel and need a breaker that actually fits and functions the way it should, the EHB2070 circuit breaker is built for that exact job. This 2-pole, 70-amp breaker was designed specifically for panelboards manufactured before 1989, making it a dependable choice when maintaining or restoring legacy electrical systems. Instead of trying to force a modern substitute, this unit aligns with the original design—so everything installs cleanly and operates as intended. It uses a thermal-magnetic trip mechanism, which means it responds to both sustained overloads and sudden short circuits. The non-interchangeable trip unit keeps protection settings consistent, which is exactly what you want in systems that were engineered with fixed parameters in mind. With a 14kA interrupting rating at 480VAC and a 40°C operating standard, it’s well-suited for real-world commercial and industrial environments. Load terminals are included, helping reduce install time and eliminate guesswork on the job.
