Product FAQs
8 answersWhat does the "SA" suffix mean on the EJB34015SA?
The "SA" suffix indicates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely for emergency shutdowns or control purposes.
How many panel spaces does the EJB34015SA require?
Although it is a 3-pole breaker, the EJB34015SA requires 4 pole spaces in the panelboard. The factory-installed shunt trip occupies the additional space.
Can I install a shunt trip on a standard EJB34015 in the field?
No. Shunt trips and other electrical accessories for Square D E-frame breakers are factory-installed only and cannot be added in the field. You must order the breaker with the "SA" suffix (EJB34015SA).
What is the control voltage for the shunt trip on this breaker?
The factory-installed shunt trip (SA suffix) operates on a control voltage of 120VAC (110 to 130VAC).
What is the recommended tightening torque for the load terminals on the EJB34015SA?
The load lugs should be torqued to 30 lbf-in (3.4 N.m) for all accepted wire sizes (14 to 6 AWG Cu or 12 to 6 AWG Al).
Is the EJB34015SA HACR and HID rated?
Yes, this breaker is both HACR (Heating, Air Conditioning, and Refrigeration) and HID (High-Intensity Discharge) rated, making it suitable for HVAC equipment and specialized lighting circuits.
What is the hold and trip current for the thermal-magnetic trip unit?
The fixed thermal-magnetic trip unit on the EJB34015SA has a holding current of 270A and a trip current of 875A.
Does the EJB34015SA feature a visual trip indicator?
Yes, it includes Square D's Visi-Trip indicator. When the breaker trips due to a fault or the shunt trip is activated, the handle snaps to a midpoint position and a highly visible red indicator appears to help quickly locate the tripped breaker.
