Product FAQs
6 answersWhat does the "SA" suffix mean on the EJB14020SA catalog number?
The "SA" suffix indicates the breaker includes a factory-installed 110-130VAC shunt trip. This allows the breaker to be opened remotely via a control signal.
How many panel spaces does the EJB14020SA occupy?
Although it is a 1-pole breaker, the factory-installed shunt trip requires an additional pole space. The EJB14020SA will occupy two total spaces in a Square D NF panelboard.
Can I field-install a shunt trip on a standard EJB14020 breaker?
No. Schneider Electric requires all electrical accessories for E-frame breakers, including shunt trips, to be factory-installed. You must order the EJB14020SA if remote tripping is required.
Which panelboards are compatible with the EJB14020SA?
This E-frame breaker is designed exclusively for bolt-on installation in Square D NF series panelboards.
What are the typical safety applications for the EJB14020SA shunt trip?
The integrated shunt trip is commonly wired into emergency stop systems, fire alarm interlocks, and equipment safety controls that require a reliable remote power disconnect.
What wire sizes are compatible with the EJB14020SA terminals?
The breaker lugs accept 14 to 6 AWG copper conductors, or 12 to 6 AWG aluminum conductors.
