Product FAQs
7 answersWhat panels accept the Q310000S07 circuit breaker?
This plug-on QP breaker is compatible with Siemens load centers and Siemens P1 panelboards designed to accept Q-frame miniature circuit breakers.
What does the S07 suffix indicate on the Q310000S07 catalog number?
The S07 suffix designates a factory-installed 24V AC shunt trip. This accessory allows the breaker to be tripped remotely by applying a 24V control signal, which is commonly used for emergency stops or automated control systems.
Is this breaker suitable for single-phase residential panels?
The Q310000S07 is a 3-pole breaker designed for 3-phase, 240V AC electrical distribution systems. It requires a 3-phase panel and is not intended for standard single-phase residential load centers.
What wire sizes are supported by the Q310000S07 terminals?
The load lugs accept 4 AWG to 1/0 AWG copper conductors, or 2 AWG to 1/0 AWG aluminum conductors.
Does this breaker require bolt-on hardware for installation?
No, the Q310000S07 features a plug-in connection. It snaps directly onto the busbar of compatible Siemens load centers and P1 panelboards, eliminating the need for bolt-on mounting hardware.
Can this 10kAIC breaker be used in systems with higher fault current requirements?
No. The Q310000S07 is rated for a maximum of 10kAIC at 240V AC. If your electrical system has an available fault current exceeding 10,000 amps, you must select a breaker with a higher interrupting rating to ensure safe operation.
What type of protection does the LI trip function provide?
The thermal-magnetic trip unit features Long-Time (L) and Instantaneous (I) functions. The thermal component provides delayed tripping for sustained overloads, while the magnetic component trips instantaneously to clear severe short circuits.
