Product FAQs
7 answersWhat does the 00S01 suffix indicate on the Siemens Q12000S01 breaker?
The 00S01 suffix designates that this breaker includes a factory-installed 120VAC shunt trip mechanism. This allows for remote tripping of the breaker, which is commonly required in commercial control systems or emergency shutdown applications.
Which load centers are compatible with the Q12000S01 circuit breaker?
This plug-on breaker is designed for use in standard Siemens load centers that accept QP type breakers. It is also backward compatible with older ITE load centers that specify QP or Q line breakers.
How do you wire the shunt trip on the Q12000S01?
The factory-installed shunt trip features its own pigtail or terminal connections separate from the primary load lug. You must supply a 120VAC control signal to these leads to actuate the remote trip mechanism. Always verify the control circuit voltage matches the 120VAC rating of the shunt trip coil.
What size and type of wire can be used with the load lug on this 20A breaker?
The primary load terminal accepts 14 AWG to 6 AWG wire and is rated for both copper (Cu) and aluminum (Al) conductors. Ensure proper torque is applied according to the manufacturer specifications printed on the breaker.
Can the Siemens Q12000S01 replace older ITE breakers with the same catalog number?
Yes, Siemens acquired ITE and continues to manufacture the QP line. The Siemens Q12000S01 is the direct, UL listed replacement for the legacy ITE Q12000S01.
When is a shunt trip breaker like the Q12000S01 typically required?
Shunt trip breakers are frequently used to meet safety codes that require remote emergency power shutdown. Common applications include commercial kitchens, elevator control rooms, and automated industrial equipment where a remote switch or fire alarm system must disconnect power to a specific circuit.
Does the addition of the shunt trip alter the standard overload and short circuit protection of the Q12000S01?
No, the breaker retains its standard thermal magnetic trip functions. It provides standard long time and instantaneous protection for overloads and short circuits, while the shunt trip simply adds a secondary, remote method to open the contacts.
