Product FAQs
7 answersWhat does the "SA" suffix mean on the EDB34090SA?
The "SA" suffix indicates the breaker is equipped with a factory-installed 120VAC shunt trip. This allows the circuit breaker to be tripped remotely by an external control signal.
How many panel spaces does the EDB34090SA require?
Because of the factory-installed shunt trip, this 3-pole breaker requires four pole spaces when installed in a Square D NF panelboard.
Can I add a shunt trip to a standard EDB34090 breaker in the field?
No. Shunt trips for Square D E-frame circuit breakers are factory-installed only and cannot be added in the field. You must purchase a breaker with the "SA" suffix if a 120VAC shunt trip is needed.
What control voltage is required for the shunt trip on this breaker?
The factory-installed shunt trip on the EDB34090SA operates on a control voltage of 120VAC (110 to 130VAC). Applying the correct voltage to the shunt trip terminals will remotely open the breaker.
How is the shunt trip on the EDB34090SA typically used?
The 120VAC shunt trip is commonly wired to fire alarm systems, emergency stop buttons, or automation controls to remotely disconnect power for safety or operational requirements.
What is the difference between Square D EDB, EGB, and EJB breakers?
While they share the same physical dimensions and mount in NF panelboards, they have different short-circuit interrupting ratings. EDB is the standard tier (18kA at 480Y/277VAC), whereas EGB and EJB provide higher interrupting capacities for systems with higher available fault currents.
Does the EDB34090SA feature a tripped circuit indicator?
Yes, it includes Square D's Visi-Trip indicator. When the breaker trips due to an overcurrent, short circuit, or shunt trip activation, the handle snaps to a midpoint position and a highly visible red indicator appears to help quickly identify the tripped breaker.
