Built for overcurrent and ground fault protection, the Siemens Q215GFH is a 15A, 2-pole miniature circuit breaker. It operates at 120/240VAC with a 22kA interrupting rating at 120/240VAC and a single circuit arrangement. This QPHF series breaker belongs to the QP family and uses plug-on mounting. It has thermal magnetic tripping, lug terminals and a pigtail neutral connection. It follows RoHS and REACh standards.
Choose the Siemens Q215GFH when the circuit requires 15A overcurrent protection. Coordinate that rating with the circuit load and conductor ampacity.
What voltage should I check before selecting this breaker?
The Q215GFH is rated 120/240VAC. Verify that the circuit's operating voltage matches this AC voltage rating before selecting it.
How does the 22kA interrupting rating affect selection?
The interrupting rating is 22kA at 120/240VAC. The available fault current at the installation point must not exceed that rating.
What protection does the Q215GFH offer beyond overload protection?
It combines overcurrent and GFCI protection. Overcurrent protection addresses overloads and short circuits, while GFCI protection responds to ground-fault leakage, making it a choice for circuits requiring both functions.
How does the thermal-magnetic trip respond to overcurrent?
The thermal element responds to sustained overloads, while the magnetic element responds rapidly to short-circuit current. This gives the breaker different responses to prolonged overloads and high-current faults.
Does plug-on mounting eliminate the need to wire the neutral connection?
No. The Q215GFH uses plug-on mounting and a pigtail neutral, so installation includes a separate wired neutral connection in addition to the plug-on breaker connection.
How are conductors secured at the breaker terminals?
The breaker uses lug terminals. Insert the conductors into the lugs and tighten the connections correctly to maintain secure electrical contact.
How does the two-pole arrangement guide circuit selection?
The Siemens Q215GFH has two poles in a single-circuit arrangement. Choose this arrangement when the circuit requires two-pole overcurrent and GFCI protection.
