EB1020 - 20Amp Circuit Breaker

EB1020 - 20Amp Circuit Breaker

The EB1020 is a 20 Amp, single-pole thermal magnetic circuit breaker commonly used in electrical panels and distribution equipment manufactured before 1989. If you're working on an older electrical system, you already know that finding the correct replacement breaker is often about maintaining compatibility rather than changing the design. The EB1020 was built for that purpose, helping keep existing equipment operating with the same form, fit, and electrical characteristics the original installation was designed around.

Many commercial properties, schools, manufacturing facilities, and public buildings continue to rely on electrical panels that have been in service for decades. When one of those systems requires maintenance, matching the original breaker specifications can help simplify repairs and preserve the panel's existing layout. The EB1020 is frequently used in these situations, making it a practical choice for electricians and maintenance teams responsible for supporting legacy electrical infrastructure.

With a 20 Amp rating, 120VAC capacity, and 10kA interrupting rating, the EB1020 is suitable for a wide range of branch circuit applications found in older electrical systems. The included load terminals can help streamline replacement work, particularly when servicing compatible EB panelboards and load centers.
