Built for advanced control requirements, this 100A breaker includes a factory-installed 120VAC shunt trip mechanism. This allows facility managers to remotely open the circuit for emergency shutdowns or automated control schemes. The device mounts into Square D NF panelboards using a secure bolt-on connection. Due to the integrated shunt trip accessory, this configuration occupies four pole spaces. Delivering 18 kAIC at 480Y/277VAC, it provides reliable thermal-magnetic protection.
Which panelboards are compatible with the EDB34100SA?
This bolt-on E-frame breaker is designed specifically for Square D NF panelboards. It cannot be installed in NQ, I-Line, or QO panels, which require different breaker frame types.
How many panel spaces does the EDB34100SA occupy?
Although it is a three-pole breaker, it requires four pole spaces in an NF panelboard. The additional space accommodates the integrated 120VAC shunt trip accessory.
What does the SA suffix mean in this part number?
The SA suffix indicates the presence of a factory-installed 120VAC shunt trip mechanism for remote circuit shutdown. If your application does not require remote tripping capabilities, you will need the standard EDB34100 catalog number instead.
What is the required control voltage for the remote trip function?
The integrated shunt trip coil requires a 120VAC control signal to operate. When the control circuit is energized, it mechanically opens the breaker contacts to disconnect power.
Can the shunt trip mechanism be removed or added in the field?
No. The 120VAC shunt trip is factory-installed by Square D. For safety and compliance, it is integrated into the breaker housing and cannot be modified, removed, or field-installed on a standard breaker.

Breaker ordered and delivered.
Called in as a last attempt because my regular supplier didn't have any of these in stock. I got a very friendly salesperson, and they sold me a new breaker for less than half of what my standard supplier would have. Definitely going here again.
