EB3020L - 20Amp Circuit Breaker

EB3020L - 20 Amp Circuit Breaker

The EB3020L circuit breaker is a 3-pole, 20-amp thermal-magnetic breaker designed for use in electrical distribution systems built around EB frame breaker configurations, particularly panels manufactured prior to 1989. With a 10kA interrupting capacity at 240VAC, this breaker helps protect branch circuits from overloads and short circuits while maintaining the proper fit and electrical characteristics required by legacy panel equipment. The non-interchangeable trip unit ensures the breaker maintains its factory-calibrated protection characteristics, supporting consistent circuit protection over time. Rated for operation at 40°C, the EB3020L is built to handle typical electrical room temperatures found in commercial and industrial environments. Line and load terminals are included, allowing for straightforward installation when replacing an existing breaker in compatible equipment. For facilities maintaining older electrical infrastructure, this model provides the correct form, fit, and functional replacement needed to keep systems operating as intended.
