Product FAQs
6 answersWhat does the PL suffix indicate on the QOB220PL?
The PL designates this as a Powerlink remotely operated circuit breaker. It features an internal motor mechanism that allows the breaker to be switched on and off remotely when integrated into automated lighting control panels.
Is the QOB220PL compatible with standard residential QO load centers?
No. Although it shares the QOB footprint, this breaker is specifically designed for Powerlink Lighting Control Systems and NQ panelboards equipped with a control bus. It requires a specialized 24 VDC control power supply to operate the remote switching mechanism.
What is the difference between the QO220PL and QOB220PL?
The QO220PL is a plug-on remotely operated breaker, while the QOB220PL uses a bolt-on mounting style. You must select the version that matches the busbar configuration of your specific panelboard.
Does remote operation bypass the breaker overload protection?
No. The QOB220PL retains its standard thermal magnetic trip functions at all times. If an overcurrent or short circuit event occurs, the breaker will trip and open the circuit safely, overriding any remote control commands.
How do I manually control the QOB220PL if the automated system is down?
Powerlink breakers can be operated manually like a standard circuit breaker. You can physically move the handle to the ON or OFF position to control the circuit during maintenance or if the 24 VDC control power is lost.
What are the control power requirements for the QOB220PL motor?
The internal motor requires a power supply capable of delivering at least two amperes at 24 VDC for a minimum of 50 milliseconds to successfully actuate the breaker mechanism.

Great price. Fast delivery. My local electric distributor wanted double for the same breaker, so it was a no brainer to order this one. Ordered another one since with the same great service.
