EB2020L - 20Amp Circuit Breaker

EB2020L - 20Amp Circuit Breaker

The EB2020L is a 20 Amp, 2-pole thermal-magnetic circuit breaker designed for use in compatible EB-series panels manufactured before 1989. If you're maintaining an existing electrical system and need a breaker that matches the original panel design, this model provides the form, fit, and function required for many legacy installations.

Built for 120/240VAC applications, the EB2020L combines thermal and magnetic trip protection to help safeguard circuits from overloads and short circuits. The thermal element responds to sustained overcurrent conditions, while the magnetic trip mechanism reacts quickly when higher fault currents occur. This combination helps support dependable circuit protection in commercial, industrial, and institutional environments where older electrical equipment remains in service.

One practical advantage of the EB2020L is that it includes both line and load terminals, helping streamline replacement and maintenance projects. Its 20 Amp rating, 2-pole configuration, and 10kA interrupting capacity make it suitable for a wide range of branch circuit applications that require compatibility with existing EB-series equipment.
