Product FAQs

6 answers
What does the 00S01 suffix indicate on this breaker?

The 00S01 suffix denotes a factory-installed 120VAC shunt trip. This feature allows the breaker to be tripped remotely via an external control signal, commonly used for emergency power-off systems or automated shutdowns.

How many panel spaces does the Q29000S01 require?

Although it is a 2-pole breaker, the attached 120VAC shunt trip coil adds an extra pole of width. It requires three standard 1-inch spaces in your load center or panelboard.

Which load centers and panelboards are compatible with this breaker?

The Q29000S01 is designed for plug-in installation in Siemens load centers and Siemens P1 panelboards. It is also UL listed for use in Murray Meter Combo, EQ Small Circuit, and Rock Solid load centers manufactured after January 2002.

Does the Q29000S01 offer arc fault or ground fault protection?

No. This is a standard thermal-magnetic breaker equipped with a shunt trip mechanism. It provides overload and short-circuit protection but does not include AFCI or GFCI circuitry.

Is the Q29000S01 HACR rated?

Yes. This breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits.

Does this breaker feature Insta-Wire connectors?

Yes. This breaker includes Siemens Insta-Wire connectors. The terminal screws are shipped backed out and ready for wire insertion, which speeds up the installation process.
