EJB34060 - 60 Amp Circuit Breaker

EJB34060 - 60 Amp Circuit Breaker

The Square D EJB34060 is a 60 Amp, 3-pole circuit breaker made for use in compatible Square D NF panelboards. It's commonly installed when an existing E-Frame breaker needs to be replaced with the same amperage and configuration, helping keep your the panel consistent without changing the original layout.

Inside the breaker is a thermal-magnetic trip unit that responds to both overloads and short circuits during normal operation. It also includes a trip indicator, giving maintenance personnel a quick way to see when the breaker has opened because of a fault. Small details like that can make troubleshooting a little faster, especially in larger electrical systems.
