EGB24020 - 20 Amp Circuit Breaker

EGB24020 - 20 Amp Circuit Breaker

When you need to replace a circuit breaker, finding one that fits your existing panel can make all the difference. The EGB24020 is a 2-pole, 20-amp E-Frame miniature circuit breaker designed as a form-, fit-, and function-compatible replacement for NF panelboards. Built for 480Y/277VAC electrical systems, it combines a dependable thermal-magnetic trip unit with a secure bolt-on mounting design to help protect circuits from overloads and short circuits while preserving the original configuration of your electrical equipment.

Whether you're restoring service after a breaker trips, performing preventive maintenance, or replacing a worn component during a scheduled shutdown, using the correct replacement part helps keep the job straightforward. The EGB24020 features an easy-to-read trip indicator, allowing electricians and maintenance personnel to quickly identify when the breaker has tripped due to a fault.
