Rated 22 kAIC at 120/240VAC, this high-interrupting capacity breaker delivers robust 30mA ground fault equipment protection (GFEP). The Siemens QE230H is a 2-pole, 30A plug-on device designed to shield commercial and industrial machinery from line-to-ground faults. It mounts into Siemens EQ, PL, ES, and Ultimate load centers, offering a reliable upgrade or exact substitute for the Q230EGH. Includes thermal-magnetic LIG protection and HACR certification for HVAC applications.
Which load centers are compatible with the QE230H breaker?
This plug-on breaker is designed for use in Siemens EQ, PL, ES, and Ultimate load centers. It will physically fit standard 1-inch spaces but must be installed in panels approved for Siemens QP or QE type breakers.
What is the ground fault trip threshold for the QE230H?
The QE230H provides Ground Fault Equipment Protection (GFEP) with a 30mA trip threshold. This is designed to protect machinery and equipment from line-to-ground faults, unlike Class A GFCI breakers which trip at 5mA for personnel protection.
What is the difference between the Siemens QE230 and the QE230H?
The H in the QE230H catalog number indicates a high interrupting rating. The QE230H is rated for 22kAIC at 240V, whereas the standard QE230 is rated for 10kAIC.
Can the QE230H replace older Siemens equipment protection breakers?
Yes, the QE230H is a direct replacement and exact substitute for the older Siemens Q230EGH model.
How is the neutral connection made on the QE230H?
This breaker features a pigtail neutral wire that must be connected directly to the neutral bus bar in the load center to ensure the ground fault equipment protection functions correctly.
Is the QE230H suitable for HVAC equipment?
Yes, this breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 30A, 2-pole GFEP breaker.
