Product FAQs
5 answersWhat is a switching neutral circuit breaker?
A switching neutral breaker, such as the QG215, is designed to simultaneously disconnect both the ungrounded hot and grounded neutral conductors when tripped or manually turned off. This ensures complete isolation of the circuit, which is required for specific specialized applications.
What applications typically require a switching neutral breaker?
They are commonly used in specialized commercial and industrial applications, such as fuel dispensing equipment and gas pumps, where safety codes mandate that all conductors, including the neutral, must be disconnected simultaneously during maintenance or a fault.
How does the neutral connection work on the QG215?
Unlike standard breakers, the neutral pole on the QG215 does not connect directly to the load center bus. Instead, one side of the neutral pole is wired to the neutral bar in the panel, and the other side connects directly to the load device.
Can I use the QG215 to replace a standard 2-pole breaker?
No. The QG215 is specifically designed as a switching neutral breaker for 120V circuits requiring both hot and neutral disconnection. It should not be used as a standard 240V 2-pole breaker for 240V loads.
What is the cross-reference or older part number for the QG215?
The Siemens QG215 serves as a direct replacement for older ITE QG215 breakers and can replace the Murray MP215SN switching neutral breaker.
