30A GFEP Miniature Circuit Breaker
20A GFEP Miniature Circuit Breaker
Description
Part of the E-Frame family, this 20-amp GFEP breaker is built to prevent equipment damage by detecting 30mA ground faults. It mounts into Square D NF panelboards via a sturdy bolt-on configuration, making it ideal for demanding industrial environments. Unlike standard 5mA personnel GFCIs, this unit prevents nuisance tripping on heavy machinery. It includes a Visi-Trip visual indicator and carries an 18kAIC rating at 277VAC for robust short-circuit defense.Specifications

Product FAQs
7 answersHow many panel spaces does the EDB14020EPD require?
Although it operates as a 1-pole circuit breaker, the EDB14020EPD requires two pole spaces in a Square D NF panelboard to accommodate the integrated ground fault equipment protection (EPD) electronics module.
Which panelboards are compatible with the EDB14020EPD breaker?
This E-frame bolt-on breaker is designed exclusively for use in Square D NF series panelboards. It cannot be installed in NQ, QO, or I-Line panelboards.
Does the EDB14020EPD provide Class A GFCI protection for personnel?
No. The EPD suffix indicates it is an Equipment Protection Device. It provides a 30mA ground fault trip threshold designed to protect machinery from damage, rather than the highly sensitive 4mA to 6mA threshold required for Class A personnel protection.
Can the EDB14020EPD be used on a 208Y/120V system?
No. According to Schneider Electric application guidelines, NF EPD circuit breakers require a 277V phase-to-ground voltage to properly power the ground fault monitoring circuitry. They are designed for 480Y/277V networks and are not suitable for 208Y/120V applications.
How does the EDB14020EPD connect to the panel neutral?
This breaker features a factory-installed pigtail neutral wire. The pigtail must be terminated at the neutral bus in the NF panelboard to enable the internal 30mA ground fault monitoring circuit.
What is the difference between the EDB14020EPD, EGB14020EPD, and EJB14020EPD?
All three are 20A, 1-pole EPD breakers for NF panelboards. They share the same physical dimensions and 30mA ground fault features but differ in their maximum short-circuit interrupting ratings. The EDB is the standard tier, while the EGB and EJB offer progressively higher interrupting capabilities.
Does the EDB14020EPD include a bell alarm switch?
No, the standard EDB14020EPD does not include auxiliary monitoring contacts. If your installation requires a factory-installed bell alarm switch, you must source the version with the BA suffix, catalog number EDB14020EPDBA.

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.
