EJB34025 - 25 Amp Circuit Breaker Description
EJB34025 - 25 Amp Circuit Breaker
When dependable circuit protection is a priority, the Square D EJB34025 delivers the performance professionals expect. This 25 Amp, 3-pole E-Frame circuit breaker is built for use in compatible Square D NF panelboards, helping protect electrical systems from overloads and short circuits in commercial and industrial applications. Its thermal-magnetic trip unit reacts to both sustained overcurrent conditions and sudden fault events, helping minimize equipment damage and reduce unplanned downtime.
The bolt-on design provides a secure installation, making the EJB34025 a practical choice whether you're replacing an existing breaker or completing a new panelboard installation. A built-in trip indicator makes it easy to identify when the breaker has tripped, saving valuable troubleshooting time during maintenance.
