EGB24045 - 45 Amp Circuit Breaker Description
EGB24045 - 45 Amp Circuit Breaker
When you're maintaining a compatible NF panelboard, choosing the right replacement breaker helps keep your electrical system operating as intended. The EGB24045 is a 2-pole, 45-amp E-Frame miniature circuit breaker designed for 480Y/277VAC applications, delivering dependable protection against overloads and short circuits while matching the form, fit, and function of compatible equipment. Its thermal-magnetic trip unit responds to both sustained overloads and fault conditions, while the built-in trip indicator makes it easy to identify when the breaker has opened, helping reduce troubleshooting time. With interrupting ratings of up to 65kA at 120VAC, 120/240VAC, and 240VAC, the EGB24045 is well suited for commercial and industrial electrical systems where reliable circuit protection is essential.
