Product FAQs
8 answersWhich panelboards are compatible with the Q33000S07 circuit breaker?
This Type QP breaker is designed for use in Siemens load centers and panelboards, including the PL and ES series. Always verify compatibility with your specific panel's wiring diagram.
What does the "00S07" suffix indicate on this Siemens breaker?
The "00S07" suffix designates that this breaker includes a factory-installed 24VAC shunt trip accessory, allowing the breaker to be tripped remotely.
Can this 3-pole breaker be used on a 3-phase system?
Yes, the 3-pole configuration and 240VAC rating make it suitable for 3-phase applications requiring 30A of overcurrent protection.
Is the Q33000S07 suitable for systems with high available fault current?
This breaker has a standard interrupting rating of 10kAIC at 240V. If your system requires a higher interrupting capacity, you will need to source a QPH (22kAIC) or HQP (65kAIC) series breaker.
What wire sizes are accepted by the terminals on this breaker?
The lugs are rated to accept 14 AWG to 6 AWG copper or aluminum conductors. Ensure proper torque specifications are followed during installation.
Can I install this Siemens QP breaker in a GE or Square D panel?
No. While it may physically fit, installing a Siemens Type QP breaker in a GE or Square D enclosure violates UL listings and compromises safety. It must only be used in approved Siemens panels.
Does this breaker require a bolt-on connection?
No, the Q33000S07 features a plug-in connection type. It snaps directly onto the bus bar of compatible load centers and panelboards.
What type of trip mechanism does the Q33000S07 utilize?
It uses a fixed thermal-magnetic trip unit, providing long-time response for overload conditions and instantaneous response for short circuits.
