Product FAQs
6 answers
Which panelboards are compatible with the EDB34110SA circuit breaker?
This bolt-on E-frame breaker is designed specifically for installation in Square D NF series panelboards.
What does the SA suffix indicate on the EDB34110SA catalog number?
The SA suffix signifies that this breaker includes a factory-installed shunt trip. This mechanism operates on a 120V AC control voltage, allowing the breaker to be tripped remotely for safety or automation purposes.
How many panel spaces does the EDB34110SA require for installation?
This breaker requires a total of four pole spaces in the panelboard. While it is a 3-pole breaker, the factory-installed shunt trip occupies one additional space.
Can the shunt trip on the EDB34110SA be installed or replaced in the field?
No. The shunt trip on Square D E-frame circuit breakers is a factory-installed component and is not field-installable or replaceable.
Is the EDB34110SA suitable for use on a 480V Delta electrical system?
No. This breaker carries a 480Y/277V slash rating, meaning it is only approved for solidly grounded Wye systems where the voltage to ground does not exceed 277V. It must not be installed on ungrounded or corner-grounded 480V Delta systems.
Does the EDB34110SA require a specific mounting hardware kit?
No separate mounting kit is required. This is a bolt-on breaker that fastens directly to the busbar of a Square D NF panelboard using the integrated mounting screws.
