Built for dedicated equipment loads, the Siemens Q220EG functions as a 20-amp, two-pole GFEP breaker. Unlike standard 5mA GFCI units, this 30mA device is calibrated specifically to prevent nuisance tripping on heat trace cables and industrial pumps. The plug-on design installs into Siemens load centers and seamlessly replaces the legacy QE220 breaker. It utilizes a pigtail neutral connection.

Product FAQs
7 answers
Which load centers accept the Siemens Q220EG?
It is designed for use in Siemens EQ, EQL, SEQ, EQG, PL, and ES series load centers.
What is the ground fault trip level for the Q220EG?
This breaker provides Ground Fault Equipment Protection (GFEP) with a 30mA trip level, designed to protect equipment from damaging line-to-ground fault currents.
When should a GFEP breaker be used instead of a Class A GFCI?
GFEP breakers like the Q220EG have a 30mA trip threshold and are used for equipment protection, such as heat tracing or snow melting systems. Class A GFCI breakers have a 5mA threshold and are required for personnel protection.
How is the pigtail neutral installed on the Q220EG?
The white pigtail wire must be connected directly to the neutral bus bar in the panel to ensure the ground fault equipment protection functions properly.
Can the Q220EG replace older Siemens or ITE breakers?
Yes, the Q220EG is the direct replacement for the older Siemens and ITE model QE220.
Does this breaker include diagnostic indicators?
Yes, it features LED trip indicators to help quickly identify fault conditions after a trip occurs.
Is the Q220EG rated for HVAC applications?
Yes, it carries an HACR rating, making it suitable for use with heating, air conditioning, and refrigeration equipment.
