EGB24025 - 25 Amp Circuit Breaker

EGB24025 - 25 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical panel, the details matter more than anything else. The EGB24025 is a 2-pole, 25-amp E-Frame miniature circuit breaker designed as a direct 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 circuits from overloads and short circuits while maintaining proper compatibility with your existing electrical setup.

In the field, this type of breaker is often chosen when you need to restore power quickly without redesigning the panel or changing the original system layout. The EGB24025 includes a clear trip indicator that makes troubleshooting easier by indicating when the breaker has opened due to a fault condition.
