Built for equipment protection, the Siemens Q215EGH miniature circuit breaker provides GFEP protection with 15A, two poles and a 120/240VAC rating. Its interrupting rating is 22kA at 120/240VAC, with single-phase operation and a single circuit arrangement. The QEHB series breaker has a Q frame, plug-on mounting and lug terminals. Fixed thermal-magnetic tripping provides long-time and instantaneous protection, and minimum wire size is 14 AWG.

Product FAQs
7 answers
What does the 15A rating mean when selecting the Siemens Q215EGH?
The 15A rating is the breaker's current rating, not an adjustable setting. Use it when selecting overcurrent protection for the circuit's conductors and load.
How do I check whether the 22kA interrupting rating is sufficient?
Compare the available fault current at the installation point with the breaker's 22kA interrupting rating at 120/240VAC. The available fault current must not exceed that rating.
What does GFEP protection do for equipment?
GFEP provides ground-fault equipment protection by interrupting the circuit when a ground-fault condition triggers the protection. Choose this feature when the circuit requires equipment ground-fault protection in addition to overcurrent protection.
Can I adjust the thermal or magnetic trip settings?
The thermal and magnetic trip settings are fixed. Thermal-magnetic operation provides delayed response to sustained overloads and instantaneous response to high fault currents, so select the breaker around its fixed protection characteristics.
What does plug-on mounting mean for installation?
Plug-on mounting makes the electrical connection by plugging the breaker into place. Plan installation around this connection method rather than a bolt-on mounting method.
What should I consider when selecting and terminating conductors?
Select conductors no smaller than 14 AWG and terminate them at the lugs. Conductor selection must also account for the circuit load and the breaker's 15A rating.
What do the voltage and pole ratings mean for breaker selection?
The Siemens Q215EGH is rated 120/240VAC and has 2 poles. Check the voltage rating against the circuit voltage and the pole count against the number of poles requiring overcurrent protection.
