Description
Built for commercial control applications, the Siemens Q26000S01 is a 60A miniature circuit breaker with a factory-installed 120VAC shunt trip for remote disconnection. This QP series plug-on unit installs into standard Siemens load centers and panelboards. Due to the attached shunt trip coil, it requires three panel spaces despite being a two-pole breaker. It delivers thermal-magnetic protection with a 10kAIC rating at 120/240VAC and features Insta-Wire connectors for faster setup.Specifications

Product FAQs
8 answersWhat does the "00S01" suffix mean on the Siemens Q26000S01?
The "00S01" suffix indicates that this breaker includes a factory-installed 120V AC shunt trip. This internal accessory allows the breaker to be tripped remotely by applying a 120V control signal, which is commonly used for emergency stop or remote shutdown applications.
Can I add a shunt trip to a standard Siemens Q260 breaker in the field?
No, Siemens Type QP miniature circuit breakers do not support field-installable internal accessories. If your application requires a 120V shunt trip, you must purchase a factory-assembled unit like the Q26000S01.
What type of panels accept the Q26000S01 breaker?
This Type QP breaker features a plug-on connection and is designed exclusively for use in compatible Siemens load centers and panelboards. It requires two adjacent spaces on the busbar.
Is the Q26000S01 compatible with aluminum wiring?
Yes, the terminal lugs on this breaker are rated for both copper (Cu) and aluminum (Al) conductors ranging from 8 AWG to 4 AWG. Always apply an approved oxide inhibitor when terminating aluminum wire.
Does the Q26000S01 provide ground-fault or arc-fault protection?
No, this is a standard thermal-magnetic breaker equipped with a shunt trip. It provides long-time and instantaneous protection against overloads and short circuits, but it does not include GFCI, AFCI, or dual-function circuitry.
What if my electrical system requires an interrupting rating higher than 10kAIC?
The Q26000S01 is rated for a maximum fault current of 10kAIC at 120/240VAC. If your panel requires a higher rating, you will need to specify a Type QPH (22kAIC) or Type HQP (65kAIC) breaker with the appropriate shunt trip suffix.
How does the thermal-magnetic trip mechanism operate on this breaker?
The breaker utilizes a fixed thermal element for long-time overload protection, which trips when the current exceeds the 60A rating over a sustained period. The magnetic element provides instantaneous tripping during severe short-circuit conditions.
Does the shunt trip require a separate power source?
Yes, the 120V AC shunt trip requires an external control voltage source to operate. When the 120V signal is applied to the accessory leads, it activates the internal solenoid to mechanically open the breaker contacts.
