Product FAQs
7 answersWhich panelboards are compatible with the QOB230PL circuit breaker?
This bolt-on breaker is designed for installation in Square D Powerlink lighting control systems and standard NQ or NQOD panelboards.
How is the remote switching wired on the QOB230PL?
The breaker includes three 18 AWG control wires for remote operation. The black wire connects to the negative terminal of a 24 Vdc power supply, the red wire connects to the positive terminal, and the white wire connects to the common terminal of the remote control device.
Can this Powerlink breaker be used without the remote control features?
Yes. If the control wires are left disconnected and properly isolated, the QOB230PL will function as a standard thermal-magnetic circuit breaker, providing conventional overcurrent and short circuit protection.
What is the difference between the QOB230 and the QOB230PL?
The standard QOB230 is a conventional miniature circuit breaker. The QOB230PL includes the PL suffix, indicating it is a Powerlink remotely operated breaker equipped with internal switching mechanisms and external control leads for automated lighting systems.
What wire gauges are compatible with the terminals on this breaker?
The pressure plate terminals accommodate 14 to 2 AWG copper conductors or 12 to 2 AWG aluminum conductors.
How does the QOB230PL indicate a tripped condition?
It features the Square D Visi-Trip indicator. When the breaker trips due to an overload or short circuit, a red flag appears in the indicator window, allowing maintenance personnel to quickly identify the faulted circuit.
What safety precautions are required when wiring the control leads?
All control wiring and splicing must comply with National Electrical Code (NEC) Class 1 circuit requirements, specifically Article 725. Ensure all power supplying the panelboard is turned off before connecting the 24 Vdc control wires.
