Product FAQs
7 answers
What does the "SA" suffix indicate on the EDB24100SA catalog number?
The "SA" suffix designates a factory-installed 120VAC shunt trip mechanism. This allows the breaker to be tripped remotely for emergency shutdown or control applications.
How many panel spaces does the EDB24100SA require in an NF panelboard?
Although it is a 2-pole breaker, the EDB24100SA requires three pole spaces. The factory-installed shunt trip accessory occupies the additional space.
Can I add a shunt trip to a standard EDB24100 breaker in the field?
No. Shunt trips for Square D E-Frame breakers are not field-installable. You must purchase a breaker with a factory-installed shunt trip, such as the EDB24100SA.
Which panelboards are compatible with the EDB24100SA?
This E-Frame breaker is designed exclusively for bolt-on installation in Square D NF series panelboards. It is not compatible with NQ or I-Line panelboards.
Does this breaker include a visual trip indicator?
Yes, it features the Square D Visi-Trip indicator. When the breaker trips due to an overcurrent or short-circuit condition, a red flag appears in the indicator window to help quickly identify the faulted circuit.
Is the EDB24100SA suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific protection rating.
Can the EDB24100SA be used on an ungrounded 480V delta system?
No. Because it has a slash voltage rating of 480Y/277V, this breaker is only suitable for solidly grounded wye systems. It cannot be used on ungrounded or corner-grounded 480V delta systems.

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.
