Product FAQs
7 answersWhat does the 00S01 suffix mean on the Q27000S01 part number?
The 00S01 suffix indicates that the breaker comes with a factory-installed 120VAC shunt trip. This allows the breaker to be opened remotely via a control signal.
What is the difference between the standard Q270 and the Q27000S01?
The Q270 is the standard 70A, 2-pole QP breaker. The Q27000S01 is the exact same breaker but includes the factory-installed 120VAC shunt trip mechanism for remote disconnect applications.
Can I add a shunt trip to a standard Siemens Q270 breaker in the field?
No. For Siemens QP series miniature circuit breakers, shunt trips and auxiliary switches must be factory-installed. You must purchase the specific breaker with the 00S01 suffix if a 120V shunt trip is required.
How does the 120VAC shunt trip function on this breaker?
The shunt trip mechanism requires an external 120V AC control signal. When voltage is applied to the shunt trip coil from a remote switch, relay, or emergency stop button, it mechanically forces the breaker to trip and open the circuit.
How much panel space does the Q27000S01 require?
This 2-pole QP breaker requires two standard 1-inch spaces in a compatible Siemens load center or panelboard.
Is this breaker compatible with older ITE or Gould load centers?
Siemens QP breakers are generally backwards compatible with older ITE and Gould load centers that accept EQ-P or QP type plug-on breakers. Always verify the specific panel label for approved replacement types.
What are common applications for a 70A breaker with a shunt trip?
These breakers are typically used in commercial and industrial settings where remote emergency shutdown is required by code. Common applications include commercial kitchen hoods, elevator control circuits, and emergency stop systems.
