Product FAQs
6 answersWhat does the 00S01 suffix indicate on the Siemens Q21500S01?
The 00S01 suffix designates a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely by applying 120V to the shunt trip coil.
Which panels accept the Q21500S01 circuit breaker?
This plug-on breaker is compatible with standard Siemens load centers and P1 panelboards that accept QP or Q frame breakers.
How is the shunt trip wired on the Q21500S01?
The factory-installed shunt trip includes pigtail leads that must be connected to a 120VAC control circuit. When the control circuit is energized, it activates the coil to open the breaker contacts.
Is the Siemens Q21500S01 HACR rated?
Yes, standard Siemens QP breakers, including this 15A model, are HACR rated for use with heating, air conditioning, and refrigeration equipment.
Can the Q21500S01 replace a standard Q215 breaker?
The Q21500S01 includes a 120VAC shunt trip for remote tripping, which typically requires an additional panel space compared to a standard breaker. If your application does not require a shunt trip, a standard Q215 is the correct replacement.
Can the Q21500S01 be used on a 208Y/120V system?
Yes, its 120/240VAC rating makes it suitable for use on 120/240V single-phase systems as well as 208Y/120V three-phase systems.
