EJB24110 SQUARE D 2P 110A 480/277V
The EJB24110 Square D circuit breaker is a reliable 2-pole solution designed for high-performance applications. With a 110A rating and operating voltage of 480/277V, it ensures optimal protection for your electrical systems. Ideal for commercial or industrial settings, this breaker guarantees safety and efficiency for your electrical installations.
The EJB24110 is an industrial/commercial MCCB designed for Square D panelboards and switchboards that accept EJB-frame bolt-on breakers — such as select NF and NQ series panelboards. It is not suitable for residential loadcentres. Because compatibility depends on your specific panelboard's breaker schedule, we recommend sending us your panelboard model number so our team can confirm before you order.
The Square D EJB frame series is considered a legacy/obsolete line and is no longer in active production. Northern Breaker Group specialises in sourcing hard-to-find and obsolete breakers like the EJB24110 — contact us for current stock availability and lead times.
Yes — a breaker rated for a higher voltage (480/277V) is generally suitable for use on lower-voltage systems such as 208Y/120V or 240V, as the insulation and interrupting ratings are designed for the higher level. However, always verify with your system engineer or authority having jurisdiction (AHJ) that the breaker's interrupt rating (65kA) meets or exceeds the available fault current at the installation point.
