EGB24100 - 100 Amp Circuit Breaker

EGB24100 - 100 Amp Circuit Breaker

When you need a 100-amp, 2-pole bolt-on circuit breaker that matches the form and fit of your existing electrical system, the EGB24100 E-Frame Miniature Circuit Breaker delivers a dependable replacement for compatible NF panelboards. Designed for commercial and industrial power distribution, this breaker combines a thermal-magnetic trip unit with a built-in trip indicator, helping protect electrical circuits from overloads and short circuits while making it easy to identify a trip.

Whether you're performing routine maintenance, replacing a damaged breaker, or restoring an existing electrical distribution system, the EGB24100 is built to provide the same form, fit, and function your equipment was designed for. Because it installs with a bolt-on mounting design, it fits securely on compatible NF panelboards without requiring modifications.
