EB2050 50A Circuit Breaker

EB2050 50A Circuit Breaker

When you're maintaining an existing electrical system, finding the right replacement breaker is often less about finding something new and more about finding something that fits and functions exactly as intended. The EB2050 is a 50 Amp, 2-pole thermal-magnetic circuit breaker designed for use in compatible EB panelboards manufactured before 1989, helping facility managers, electricians, and maintenance professionals keep legacy electrical systems operating as originally designed.

Built with a non-interchangeable trip unit and rated for 120/240VAC applications, the EB2050 provides protection against overloads and short circuits through its thermal-magnetic design. The thermal element responds to prolonged overcurrent conditions, while the magnetic mechanism reacts quickly when higher fault currents occur. With a 10kA interrupting capacity and included load terminals, this breaker is well-suited for maintaining existing commercial, industrial, institutional, and facility electrical distribution systems.
