EJB34110 - 110 Amp Circuit Breaker Description
EJB34110 - 110 Amp Circuit Breaker
The Square D EJB34110 is a 110 Amp, 3-pole thermal-magnetic circuit breaker used in compatible Square D NF panelboards. It's commonly selected when you're replacing an existing EJB-series breaker with the same amperage, pole configuration, and voltage rating, helping keep the panel exactly as it was originally designed. That makes it a practical choice for maintenance work, repairs, and equipment upgrades where matching the existing breaker is important.
