Product FAQs
7 answersWhat does the SA suffix mean on the EDB24020SA circuit breaker?
The SA suffix indicates that this breaker includes a factory-installed 120V AC (110-130V AC) shunt trip. This allows the breaker to be tripped remotely for emergency disconnects, fire alarm integration, or control system automation.
Can I add a shunt trip to a standard EDB24020 breaker in the field?
No, shunt trips for Square D E-Frame breakers are factory-installed only and cannot be added in the field. If your application requires remote tripping capabilities, you must specify a breaker with the SA suffix, such as the EDB24020SA.
Does the factory-installed shunt trip require extra space in the panelboard?
Yes, the factory-installed shunt trip on the EDB24020SA takes up an additional pole space in the NF panelboard compared to a standard two-pole EDB breaker.
What type of panelboards accept the EDB24020SA breaker?
This E-Frame breaker is designed exclusively for bolt-on installation in Square D NF series panelboards, which are typically used for commercial and industrial lighting and distribution applications.
How does the Visi-Trip indicator work on this breaker?
The EDB24020SA features Square D's Visi-Trip visual indicator. When the breaker trips due to a fault, the handle snaps to a midpoint position and a highly visible red indicator appears, allowing you to quickly identify the tripped breaker in a crowded panel.
Is the EDB24020SA rated for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires HACR-type circuit protection.
Is this breaker suitable for switching high-intensity discharge lighting?
Yes, the EDB24020SA is HID rated, making it suitable for switching high-intensity discharge lighting loads safely without nuisance tripping.
