Product FAQs
8 answersWhat does the 00S01 suffix indicate on this Siemens breaker?
The 00S01 suffix designates a factory-installed 120V AC shunt trip accessory. This feature allows the breaker to be opened remotely via an external control signal, which is commonly used for emergency stop circuits or automated equipment shutdowns.
Can the Q34000S01 be used in a standard residential load center?
This is a 3-pole breaker designed for 3-phase systems. It requires three adjacent bus stabs and cannot be installed in a standard 120/240V single-phase residential load center. It must be installed in a 3-phase Siemens load center or P1 panelboard.
How is the shunt trip accessory wired on the Q34000S01?
The factory-installed shunt trip includes external pigtail wires that exit the side of the breaker housing. These leads must be connected to a 120V AC control circuit and a momentary normally open switch to activate the remote trip function.
Can the Q34000S01 be applied on systems exceeding 10kA available fault current?
The breaker has a standalone interrupting rating of 10kA at 240V AC. It can only be applied on systems with higher fault currents if it is installed downstream of a fully rated main breaker as part of a UL-listed series combination specified by Siemens.
What are the conductor requirements for the Q34000S01 terminals?
The mechanical lugs are rated for both copper and aluminum conductors. They accept 8 to 6 AWG copper or 8 to 4 AWG aluminum wire. Always torque the terminals to the exact specifications printed on the breaker label to prevent overheating.
Does the Q34000S01 provide personnel ground fault protection?
No. This unit features standard thermal-magnetic trip technology for overload and short-circuit protection. It does not contain GFCI or AFCI circuitry.
Is the Siemens Q34000S01 compatible with older ITE load centers?
Siemens Type QP breakers are the direct modern replacements for older ITE and Gould EQ-P breakers. However, you must verify the wiring diagram inside the specific legacy panel to confirm that Type QP breakers are listed as acceptable.
Does the Q34000S01 require a bolt-on connection?
No. The Q34000S01 is a Type QP breaker, which utilizes a plug-on mounting design. It snaps directly onto the busbar of compatible panels and does not use bolt-on tabs.
