EGB24030 - 30 Amp Circuit Breaker Description
EGB24030 - 30 Amp Circuit Breaker
When you're replacing a circuit breaker in an existing panelboard, getting the correct match is what keeps everything working smoothly. The EGB24030 is a 2-pole, 30-amp E-Frame miniature circuit breaker designed as a form, fit, and functional replacement for compatible NF panelboards. Built for 480Y/277VAC systems, it uses a dependable thermal-magnetic trip unit to help protect electrical circuits from overloads and short circuits while maintaining compatibility with the original panel design.
