Description
Engineered for commercial facilities, the Square D EJB14030EPD provides specialized 30mA ground fault equipment protection. This 30A, 1-pole breaker prevents electrical damage to industrial machinery by detecting low-level leakage currents. The device mounts into Square D NF panelboards using a secure bolt-on configuration. With an impressive 100kAIC rating at 120VAC, it handles severe fault conditions reliably. The breaker incorporates a Visi-Trip indicator and is HACR and HID rated.Specifications

Product FAQs
6 answersHow much panel space does the EJB14030EPD require?
Although it is a 1-pole circuit breaker, it requires two pole spaces (1.96 inches wide) in the panelboard to accommodate the internal ground-fault circuitry.
What is the difference between this EPD breaker and a Class A GFCI?
This EPD (Equipment Protection Device) has a 30mA ground-fault trip threshold designed to protect equipment, such as heat trace cables, from damage. Class A GFCI breakers feature a highly sensitive 5mA threshold specifically required for personnel protection.
Which panelboards accept this E-frame breaker?
The bolt-on EJB14030EPD is engineered exclusively for use in Square D NF series panelboards.
How does the EJB frame compare to EDB and EGB breakers?
EJB models provide the highest interrupting ratings in the Square D E-frame family. They deliver 100kA at 120VAC and 65kA at 277VAC, whereas EDB and EGB breakers have lower fault-current withstand limits but share the exact same physical footprint.
How is the neutral connection handled on this breaker?
It is equipped with a pigtail neutral wire that must be tied directly to the panelboard neutral bar to power the internal ground-fault sensing equipment.
Can the EJB14030EPD replace lower-rated E-frame EPD breakers?
Yes. Because it utilizes the identical mounting footprint, this high-interrupting breaker can directly replace EDB14030EPD or EGB14030EPD breakers in applications requiring upgraded short-circuit ratings.
