Product FAQs
9 answersWhat does the 00S01 suffix indicate on the Q210000S01 part number?
The 00S01 suffix designates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely from a distant control station or emergency stop button.
Can this breaker replace a discontinued Murray shunt trip breaker?
Yes, the Q210000S01 functions as an exact, UL listed replacement for the discontinued Murray MP2100ST circuit breaker.
Which load centers accept the Q210000S01 circuit breaker?
This Type QP breaker is designed for plug-on installation in standard Siemens load centers and panelboards that accept 1-inch per pole breakers. It requires two adjacent spaces on the busbar.
How is the 120V shunt trip wired on this Siemens breaker?
The shunt trip mechanism requires a separate 120VAC control circuit. When voltage is applied to the shunt trip coil via an external switch or relay, it mechanically trips the breaker to open the main contacts.
What wire sizes are supported by the lugs on the Q210000S01?
The load lugs accept 8 AWG to 2/0 AWG copper or aluminum conductors. Ensure proper torque is applied during installation as specified on the breaker label to prevent overheating.
Is this breaker suitable for applications requiring remote disconnects?
Yes, the integrated 120V shunt trip makes it ideal for commercial environments where a remote disconnect is required for safety or equipment control, such as in HVAC or refrigeration systems.
Does the Q210000S01 provide ground fault or arc fault protection?
No, this is a standard thermal magnetic breaker with a shunt trip accessory. It does not include GFCI or AFCI protection circuitry.
Can I install this QP breaker in a bolt-on panelboard?
No, the Q210000S01 is a Type QP breaker which features a plug-on connection. If your Siemens panelboard requires bolt-on breakers, you will need the equivalent Type BL breaker.
What does the LI trip function code mean for this breaker?
The LI designation indicates that the breaker provides Long-Time and Instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function protects against short circuits.
