EF2B020 - 20 Amp Circuit Breaker

EF2B020 - 20 Amp Circuit Breaker

When you're maintaining an existing electrical system, choosing the correct replacement breaker is just as important as the installation itself. The EF2B020 is a 20 Amp, 2-pole Type EF2 molded case circuit breaker designed to match compatible electrical equipment without changing the original system layout. Whether you're replacing a worn breaker during scheduled maintenance or restoring a legacy electrical panel, this unit provides the form, fit, and function needed to help keep your equipment operating as intended.

Rated for 20 amps, the EF2B020 offers interrupting capacities of 18 kA at 240 VAC and 14 kA at 480 VAC and 600 VAC, making it suitable for a variety of commercial and industrial electrical systems. Its molded case construction helps protect circuits from overloads and short circuits while fitting into compatible Type EF2 installations.
