Product FAQs

4 answers
What does the PL suffix indicate on the QOB120PL circuit breaker?

The PL designation means this is a Powerlink remotely operated breaker. It integrates an internal motor mechanism for automated switching of lighting zones, typically controlled by a facility management system.

Which panelboards accept the QOB120PL breaker?

This bolt-on breaker is designed exclusively for Square D Powerlink lighting control panels and compatible NQOD panelboards.

Is the QOB120PL rated for HVAC equipment?

Yes, this breaker carries an HACR rating, approving it for use with heating, air conditioning, and refrigeration applications.

Does the remote switching feature override the thermal-magnetic protection?

No. The remote operation is strictly for automated control. The breaker retains its fixed thermal-magnetic elements to provide reliable long-time and instantaneous trip protection during overloads or short circuits.
