EHB3020 - 20Amp Circuit Breaker

EHB3020 - 20Amp Circuit Breaker

If you're maintaining an existing electrical system, finding the correct replacement breaker matters. The EHB3020 is a 3-pole, 20-amp Type EHB thermal-magnetic circuit breaker designed as a form, fit, and functional replacement for compatible panelboards manufactured before 1989. Instead of modifying your existing setup, this breaker is built to match the original design and electrical ratings of compatible equipment, helping keep your system operating as intended.

The EHB3020 combines thermal and magnetic trip protection to respond to both prolonged overloads and short-circuit conditions. Its non-interchangeable trip unit preserves the original breaker configuration, making it a practical choice for maintaining legacy electrical distribution systems in commercial and industrial facilities.

Where It Works Best

The EHB3020 Type EHB circuit breaker is a good fit for maintaining compatible legacy electrical distribution systems found in manufacturing facilities, warehouses, schools, office buildings, healthcare facilities, and other commercial or industrial properties. It's intended for applications where the original panelboard was manufactured before 1989 and requires a replacement breaker with matching electrical ratings and physical configuration. Using the correct replacement helps maintain the existing system design while supporting safe, reliable operation of compatible equipment.
