EGB24125 - 125 Amp Circuit Breaker Description
EGB24125 - 125 Amp Circuit Breaker
When an existing electrical system needs a replacement breaker, choosing one that's designed for the original installation can save time and help keep your project moving. The EGB24125 E-Frame Miniature Circuit Breaker is a 125-amp, 2-pole bolt-on circuit breaker engineered for use in compatible NF panelboards, making it an ideal solution for maintaining commercial and industrial electrical distribution systems. Rather than adapting your equipment or making unnecessary modifications, this breaker is built to provide the form, fit, and function your existing system was designed to use.
Whether you're replacing a breaker during scheduled maintenance, restoring service after an unexpected fault, or servicing an existing panelboard, the EGB24125 is designed to make installation straightforward.
