EGB24080 - 80 Amp Circuit Breaker

EGB24080 - 80 Amp Circuit Breaker

Finding the right replacement circuit breaker can make all the difference when maintaining an existing electrical system. The EGB24080 E-Frame Miniature Circuit Breaker is a 2-pole, 80-amp bolt-on breaker designed specifically for use in compatible NF panelboards, making it an excellent choice when you need the correct form, fit, and function for your existing installation. Equipped with a thermal-magnetic trip unit, it responds to both sustained overloads and sudden short circuits to help protect electrical circuits and connected equipment. A built-in trip indicator gives you a quick visual indication when the breaker has operated, helping simplify inspections and maintenance.
