Description
Built to handle the demanding inrush currents of commercial lighting, the QO220HID is a 2-pole, 20A plug-on circuit breaker from Square D. It carries a specific HID rating, making it the correct choice for circuits feeding fluorescent, metal halide, or sodium vapor lighting systems. This thermal-magnetic breaker mounts into standard QO load centers and NQ panelboards, delivering a 10kA interrupting capacity at 120/240VAC. It includes the Visi-Trip indicator flag to easily identify faults.Specifications

Product FAQs
7 answersWhat does the HID suffix indicate on the QO220HID breaker?
The HID designation means this breaker is rated for switching High Intensity Discharge lighting systems, such as metal halide or high pressure sodium fixtures. It features larger contacts and modified magnetic characteristics to handle the high starting inrush currents typical of these inductive loads.
Can the QO220HID be used as a direct replacement for a standard QO220?
Yes, the QO220HID is physically interchangeable with standard 2-pole QO circuit breakers. It provides the same thermal-magnetic protection while offering enhanced durability for high-inrush lighting loads.
Which load centers and panelboards accept the QO220HID?
This plug-on breaker is compatible with Square D QO load centers, NQ panelboards, and Speed-D switchboard distribution panels. It cannot be installed in Homeline panels or bolt-on NQOD configurations.
What wire sizes and materials are compatible with the QO220HID terminals?
The pressure plate terminals on this breaker accept 14 AWG to 8 AWG copper or aluminum conductors.
Is the QO220HID suitable for switching fluorescent lighting circuits?
Yes. Circuit breakers marked for HID applications are also approved for switching standard fluorescent lighting circuits, as they meet and exceed the requirements of standard SWD (Switching Duty) ratings.
How does the Visi-Trip feature work on this breaker?
The QO220HID includes a Visi-Trip indicator that displays a highly visible red flag in the breaker window when it trips due to an overcurrent or short circuit. This allows personnel to quickly identify the faulted circuit in a crowded panel.
What is the difference between QO and QOB HID breakers?
QO models like the QO220HID feature a plug-on mounting design for QO load centers and NQ panelboards. QOB models are the bolt-on equivalent designed specifically for NQ and NQOD panelboards where a bolted connection to the busbar is required.
