EB3050 - 50Amp Circuit Breaker

EB3050 - 50Amp Circuit Breaker

Keeping legacy electrical systems operating safely often comes down to finding the correct replacement components that match the original equipment specifications. The EB3050 Type EB circuit breaker is designed for use in compatible Type EB panelboards manufactured before 1989, making it a practical solution for maintaining existing electrical distribution systems without altering original panel configurations.

This 50 amp, 3-pole thermal-magnetic circuit breaker provides protection against overloads and short-circuit conditions in compatible three-phase electrical systems. Its non-interchangeable trip unit helps maintain the operating characteristics intended for Type EB installations, while the included load terminals simplify replacement and maintenance projects.

Whether you're using it in a manufacturing facility, office building, educational campus, healthcare institution, or government property, the EB3050 provides the ratings and configuration required for compatible Type EB panelboard applications. For organizations focused on preserving existing electrical infrastructure, it offers a dependable replacement option designed around the original equipment specifications.
