Product FAQs
9 answersWhat does the "SA" suffix indicate on the EGB34100SA circuit breaker?
The "SA" suffix indicates that this breaker includes a factory-installed 120VAC shunt trip mechanism. This allows the breaker to be tripped remotely for emergency shutdowns or control purposes.
Does the factory-installed shunt trip change the physical space requirements of the EGB34100SA?
Yes. The factory-installed shunt trip mechanism requires an additional pole space in the NF panelboard. This means the 3-pole EGB34100SA will occupy four pole spaces on the panel bus.
Can I add or remove the shunt trip mechanism on the EGB34100SA in the field?
No. The shunt trip mechanism on Square D E-Frame breakers is factory-installed only and cannot be added, removed, or modified in the field.
Which panelboards are compatible with the EGB34100SA breaker?
This E-Frame breaker is designed specifically for use in Square D NF series panelboards. It features a bolt-on connection that mounts directly to the NF panel bus.
How does the interrupting capacity (AIC) of the EGB34100SA change based on system voltage?
The breaker provides a 65kAIC rating for 120VAC and 240VAC systems. For higher voltage applications at 277VAC or 480Y/277VAC, the interrupting capacity is 35kAIC. Always verify the available fault current at your installation point.
What is the difference between the EGB34100SA and the EDB or EJB versions?
The difference lies in the interrupting capacity (AIC) rating at 480Y/277VAC. EDB breakers are standard interrupting (18kAIC), EGB breakers are high interrupting (35kAIC), and EJB breakers are extra-high interrupting (65kAIC). All three share the same physical E-Frame dimensions.
What are the wire gauge limits for the EGB34100SA terminals?
The standard lugs accept 14 AWG to 2/0 AWG copper wire, or 12 AWG to 2/0 AWG aluminum wire. Ensure proper torque specifications are followed during installation.
Are the trip settings on the EGB34100SA adjustable?
No. This breaker features a fixed thermal-magnetic trip unit with Long-Time (L) and Instantaneous (I) trip functions. Neither the thermal overload nor the instantaneous magnetic trip thresholds can be adjusted in the field.
Does the EGB34100SA feature a visual trip indicator?
Yes, this breaker includes Square D Visi-Trip technology. When the breaker trips, a highly visible red indicator appears, allowing maintenance personnel to quickly identify the faulted circuit in a crowded NF panelboard.
