Description
Designed for industrial and commercial applications, this 30mA ground fault equipment protector prevents machinery damage. It features thermal-magnetic trip technology with a 10kAIC rating at 120VAC. The module installs onto standard 35mm DIN rails, making it ideal for custom OEM control panels. Line and load lugs are included for straightforward wiring. Unlike standard personnel safety devices, the 30mA threshold prevents nuisance tripping on equipment. It carries a HACR rating.Specifications

Product FAQs
8 answersWhat is the ground fault trip threshold for the THQC1130GFEP?
This GFEP (Ground Fault Equipment Protection) breaker features a 30mA trip threshold. It is designed to protect sensitive equipment from electrical damage without the nuisance tripping associated with 5mA personnel GFCIs.
How is the THQC1130GFEP circuit breaker mounted?
This breaker features a lug-to-lug (cable-in/cable-out) connection type. It is designed to be mounted on a standard 35mm DIN rail or base-mounted within OEM panels and enclosures.
Can I install this THQC breaker in a standard GE residential load center?
No. THQC frame breakers are lug-to-lug devices intended for DIN rail or base mounting in control panels. They do not plug into or bolt onto the busbars of standard GE Q-Line load centers, which require THQL or THQB breakers.
Is this 30A GFEP breaker suitable for personnel protection in wet areas?
No. This breaker provides Ground Fault Equipment Protection (GFEP) with a 30mA trip level. It is not a Class A GFCI and does not meet the 5mA threshold required for personnel protection in areas like bathrooms, kitchens, or pools.
What wire sizes are accepted by the terminals on this 30A breaker?
The feed-thru lugs accept 14 to 8 AWG copper (Cu) wire, or 12 to 8 AWG aluminum (Al) wire. Ensure proper torque is applied during installation.
How do I connect the neutral for the ground fault function?
The breaker is equipped with a pigtail neutral wire. This pigtail must be connected directly to the neutral bar in your panel or enclosure to power the internal ground fault detection circuitry.
What types of applications are best suited for a 30mA GFEP breaker?
GFEP breakers are typically used for commercial and industrial applications such as heat tracing, snow melting equipment, and automated machinery where low-level ground faults could damage equipment but a 5mA GFCI would cause nuisance tripping.
Is there a higher interrupting rating version of this 30A GFEP breaker?
Yes. While the THQC1130GFEP has a 10kAIC rating at 120V, the THHQC1130GFEP is the high-interrupting version, offering a 22kAIC rating for applications requiring higher fault current protection.

These breakers matched perfectly for my main AC supplies for my boat. I had the original 43-year-old Chinese (GenFu) breakers that failed and these GEs were a perfect match. My only reservation for not providing a 5-star review is breakers do not arrive in GE's original packaging which can lead to questions whether they are truly "new" breakers. Otherewise, happy I found some that replaced my originals. Thanks SB!
