Description
Rated 22 kAIC at 120/240V, this Siemens QE240H miniature circuit breaker delivers reliable 30mA ground fault equipment protection (GFEP). It is designed to safeguard machinery and outdoor equipment from damaging line-to-ground faults without tripping as easily as a 5mA personnel GFCI. The 2-pole, 40A breaker features a plug-on mounting style for quick installation into Siemens EQ, PL, ES, and Ultimate load centers. This unit has been superseded by the newer Q240EGH in current catalogs.Specifications

Product FAQs
6 answersWhat is the ground fault trip threshold for the Siemens QE240H?
The QE240H is a Ground Fault Equipment Protection (GFEP) breaker with a 30mA trip threshold. It is designed to protect machinery from line-to-ground faults, unlike Class A GFCI breakers which have a 5mA threshold for personnel protection.
Which Siemens load centers accept the QE240H breaker?
This breaker is compatible with Siemens EQ, PL, ES, and Ultimate load centers. Ensure the panel label designates type QE or QE2 breakers for proper installation.
What is the difference between the Siemens QE240 and the QE240H?
The H suffix indicates a higher interrupting rating. The QE240H is rated at 22kAIC at 240V, while the standard QE240 is rated at 10kAIC.
Is there a newer replacement for the QE240H?
Yes, in current Siemens catalogs, the QE240H has been superseded by the Q240EGH. Both provide 40A, 2-pole, 30mA equipment protection with a 22kAIC rating.
How is the pigtail neutral connected on this breaker?
The attached white pigtail wire must be routed and terminated directly to the neutral bus bar in the load center to power the internal ground fault circuitry.
What applications require a 30mA GFEP breaker like the QE240H?
GFEP breakers are typically required for heat trace cables, snow melting equipment, and specific machinery where a 5mA GFCI would cause nuisance tripping, but equipment-level ground fault protection is still mandated by the NEC.
