Description

Engineered to safeguard machinery, this 20A Q-Line breaker integrates 30mA ground fault equipment protection. It delivers reliable thermal-magnetic overcurrent defense. The module mounts into standard GE Q-Line and PowerMark Gold load centers. It includes a factory-installed pigtail neutral wire to facilitate accurate ground fault monitoring. By utilizing a 30mA threshold instead of the standard 5mA limit, it avoids nuisance tripping on industrial equipment. The device is HACR rated.

Product FAQs

6 answers
Which electrical panels are compatible with the THQL1120GFEP breaker?

This breaker is designed for use in GE Q-Line and PowerMark Gold load centers. It features a standard 1-inch plug-in mounting design.

What is the ground fault trip threshold for the THQL1120GFEP?

This breaker features a 30mA ground fault equipment protection (GFEP) trip threshold. It is designed to protect machinery and equipment from damage, unlike Class A GFCI breakers which trip at 5mA for personnel protection.

Is the THQL1120GFEP interchangeable with the THQL1120GF?

No. The THQL1120GFEP provides 30mA equipment protection, while the THQL1120GF is a Class A GFCI breaker that trips at 5mA for personnel safety. They cannot be swapped if local codes require Class A personnel protection.

How is the neutral connection made on the THQL1120GFEP?

This breaker includes a factory-installed pigtail neutral wire. The pigtail must be connected directly to the neutral bus bar in the panel to ensure accurate ground fault monitoring.

What applications typically require a 30mA GFEP breaker like the THQL1120GFEP?

30mA equipment protection breakers are commonly used for heat tracing cables, snow melting equipment, and dedicated industrial machinery where a standard 5mA GFCI might experience nuisance tripping.

Why is the THQL1120GFEP listed under both ABB and General Electric?

ABB acquired GE Industrial Solutions. Depending on the manufacturing date, this breaker may feature either GE or ABB branding. The form, fit, and function remain identical regardless of the label.
