Product FAQs
5 answersWhat does the "SA" suffix indicate on the EJB34060SA catalog number?
The "SA" suffix means this breaker includes a factory-installed shunt trip designed for 120V AC (110 to 130V AC) control circuits. This allows the breaker to be opened remotely for emergency power-off or automation systems. Shunt trips for Square D E-frame breakers are factory-installed only and cannot be added in the field.
Does the EJB34060SA require extra space in an NF panelboard due to the shunt trip?
Yes. In Square D E-frame breakers, factory-installed electrical accessories like the shunt trip (SA suffix) require an additional pole space in the NF panelboard. While this is a 3-pole breaker, it will occupy four pole spaces on the bus.
Can the EJB34060SA be used on an ungrounded 480V Delta system?
No. The 480Y/277V AC rating indicates this breaker is only suitable for solidly grounded wye systems where the voltage to ground does not exceed 277V. It is not rated for 480V ungrounded, corner-grounded, or resistance-grounded delta systems.
Can I add an auxiliary switch or alarm switch to the EJB34060SA in the field?
No. All internal electrical accessories for Square D E-frame circuit breakers, including shunt trips, auxiliary switches, and alarm switches, are factory-installed only. They cannot be retrofitted or modified in the field.
Can the EJB34060SA be used in a series-rated combination?
Yes, Square D EJB breakers are often used in series-rated systems within NF panelboards to achieve higher overall short-circuit current ratings. You must consult the series rating tables published by Schneider Electric or the labeling on your specific NF panelboard to verify approved main and branch breaker combinations.
