Description
Rated for 30 amps, the GE THQB2130GFEP is a two-pole breaker focused on equipment-level ground fault protection. Operating at a 30mA trip sensitivity, it protects industrial equipment from electrical faults. The breaker installs into GE A-Series panelboards and AQ lighting panels. Its bolt-on mounting style ensures a stable connection, while the box lugs accept 14-8 AWG copper or 12-8 AWG aluminum wiring. Providing 10kAIC at 120/240VAC, this device includes an internal common trip mechanism.Specifications

Product FAQs
6 answersWhat is the difference between GFEP and GFCI protection?
GFEP (Ground Fault Equipment Protection) breakers, like the THQB2130GFEP, trip at a 30mA threshold to protect equipment such as heat tracing or snow melting systems. GFCI (Class A) breakers trip at a 5mA threshold to protect personnel from electric shock.
What panels are compatible with the THQB2130GFEP?
This bolt-on circuit breaker is designed for use in GE A-Series panelboards and GE AQ lighting panels. It will not fit in standard residential plug-on load centers.
Can I use a THQL breaker instead of a THQB breaker?
No. THQB breakers feature a bolt-on mounting style for commercial panelboards, while THQL breakers use a plug-in mounting style for residential load centers. They are not interchangeable.
Do I need to connect the pigtail neutral if my 240V load does not use a neutral wire?
Yes. The pigtail neutral must be connected to the panel neutral bus bar to power the internal ground fault sensing circuitry of the breaker, even if the 240V load itself does not require a neutral connection.
What applications typically require a 30mA GFEP breaker?
A 30mA Ground Fault Equipment Protection (GFEP) breaker is typically required for dedicated equipment circuits where standard 5mA GFCI protection would cause nuisance tripping. Common applications include heat trace cables, snow melting equipment, and industrial pumps.
Does the THQB2130GFEP provide standard short circuit and overload protection?
Yes. In addition to 30mA ground fault equipment protection, this thermal-magnetic breaker includes fixed long-time and instantaneous trip functions to protect against standard overloads and short circuits.
