EB2020 - 20Amp Circuit Breaker

EB2020 - 20Amp Circuit Breaker

The EB2020 is a 20 Amp, 2-pole thermal magnetic circuit breaker commonly used in electrical panels and distribution equipment manufactured before 1989. If you're maintaining an older electrical system, finding the correct replacement breaker is often about preserving the original panel design and protection scheme rather than making changes to equipment that continues to serve its purpose. The EB2020 was designed for exactly that role, helping maintain compatibility within existing EB panel installations while keeping the original form, fit, and electrical characteristics intact.

Many commercial buildings, schools, industrial facilities, and municipal properties continue to rely on electrical infrastructure that has been operating for decades. When maintenance or repairs become necessary, matching the original breaker specifications can help simplify the process and keep the electrical system consistent with its intended design. That's why the EB2020 is frequently used during panel repairs, preventative maintenance projects, and restoration work involving legacy electrical equipment.

As a 2-pole breaker, the EB2020 is designed for applications where both legs of a 120/240VAC circuit need to be switched and protected together. It's commonly found serving dedicated branch circuits and other installations requiring coordinated two-pole protection. With a 20 Amp rating and 10kA interrupting capacity, it is suitable for a variety of applications found throughout older electrical systems. The included load terminals can also help simplify replacement work when servicing compatible panelboards and load centers.
