Product FAQs
6 answersIs the EGB34070SA compatible with NQ or I-Line panelboards?
No, this E-frame circuit breaker features a bolt-on connection designed specifically for Square D NF series panelboards. It will not fit NQ, NQOD, or I-Line panels.
Does the EGB34070SA require extra mounting space?
Yes. The SA suffix indicates a factory-installed 120VAC shunt trip module, which increases the physical footprint of the breaker. Because of this added accessory, it occupies four pole spaces in an NF panelboard instead of the standard three spaces.
Can I remove or field-install the shunt trip on this breaker?
No. Square D E-frame electrical accessories, including the shunt trip on the EGB34070SA, are factory-installed only. The accessory module cannot be field-modified, removed, or added to a standard breaker.
What is the difference between the EGB34070 and EGB34070SA catalog numbers?
The EGB34070 is the standard three-pole 70A circuit breaker. The EGB34070SA includes a factory-installed 120VAC shunt trip package for remote actuation, which also makes the unit wider than the standard model.
Can I adjust the trip characteristics on the EGB34070SA?
No. This unit is equipped with a thermal-magnetic trip unit featuring fixed long-time and instantaneous trip elements. Neither the thermal nor the magnetic thresholds are adjustable in the field.
How does the built-in shunt trip on the EGB34070SA function?
The factory-installed 120VAC shunt trip coil allows the breaker to be actively tripped by an external control signal. This capability is commonly integrated into emergency power-off (EPO) systems or automated safety shutdown controls to quickly de-energize the circuit.
