EGB34110 - 110 Amp Circuit Breaker

EGB34110 - 110 Amp Circuit Breaker

Keeping your electrical distribution system operating safely starts with using the right replacement breaker. The EGB34110 110 Amp 3-pole circuit breaker is designed for use in compatible NF panelboards, delivering dependable protection against overloads and short circuits while maintaining the proper form, fit, and function for existing electrical systems. Its bolt-on mounting design provides a secure installation, and the built-in trip indicator allows maintenance personnel to quickly identify when the breaker has operated, helping reduce troubleshooting time and improve service efficiency. Built with a thermal-magnetic trip unit, the EGB34110 responds to both sustained overload conditions and sudden short-circuit faults, helping protect connected equipment and branch circuits.
