EB1020 - 20Amp Circuit Breaker

EB1020 - 20 Amp Circuit Breaker

The EB1020 circuit breaker is a 1-pole, 20-amp thermal-magnetic breaker built for use in electrical panels manufactured prior to 1989 that require an EB frame breaker. It provides reliable overcurrent protection for 120VAC branch circuits, helping safeguard wiring and connected equipment from overloads and short-circuit conditions. The thermal-magnetic trip mechanism reacts to prolonged overcurrent as well as instantaneous faults, providing balanced circuit protection in everyday operation.

This breaker includes factory load terminals and features a non-interchangeable trip unit, which keeps the protection characteristics fixed as originally designed for compatible panelboards. With a 10k A.I.C. interrupting rating at 120VAC and a 40°C ambient temperature rating, the EB1020 is suitable for maintaining older electrical distribution systems where EB frame breakers are specified. Its construction follows the straightforward design typical of molded case breakers used in legacy installations and is built to last when used within its rated operating conditions.

Where It Works Best

• The EB1020 is commonly used in applications where existing equipment requires EB frame breakers, including electrical panelboards produced before 1989, maintenance or repair of legacy commercial and industrial electrical systems, facilities maintaining original electrical distribution equipment, and 120VAC branch circuits requiring 20-amp overcurrent protection. Because it matches the original form, fit, and ratings of EB frame breakers, the EB1020 is well suited for keeping older electrical panels operating as intended without altering the system design.
