Product FAQs
6 answersWhat does the 00S01 suffix indicate on the Q37000S01 breaker?
The 00S01 suffix designates a factory-installed 120V AC shunt trip. This allows the breaker to be tripped remotely via an external control signal, commonly used for emergency stop circuits or fire alarm interfaces.
What are the wire size and temperature requirements for the Q37000S01 lugs?
The terminals accept 4 AWG to 1/0 AWG copper or 3 AWG to 2/0 AWG aluminum conductors. Because this is a 70A breaker, Siemens requires the use of 75C rated wire.
Which panels accept the Siemens Q37000S01 breaker?
This QP series breaker is designed for plug-in installation in Siemens load centers and panelboards that accept 3-pole, 1-inch per pole branch breakers.
Can the Q37000S01 replace an older ITE breaker with the same catalog number?
Yes. Siemens acquired ITE, and this current production QP breaker is the direct, UL-listed replacement for legacy ITE Q37000S01 models.
Is the Q37000S01 suitable for HVAC applications?
Yes, Siemens QP series breakers are HACR rated, making them compliant for protecting heating, air conditioning, and refrigeration equipment that requires a 70A disconnect.
How much panel space does the Q37000S01 require?
As a 3-pole QP breaker, it requires three standard 1-inch spaces in a compatible load center or panelboard.
