Product FAQs
7 answersWhat panelboards are compatible with the Square D QOB115HID circuit breaker?
This bolt-on breaker is designed for use in Square D NQ and NQOD panelboards.
What does the HID designation mean on this QOB breaker?
HID stands for High Intensity Discharge. This breaker is specifically engineered to handle the high inrush currents and inductive loads typical of commercial lighting systems, such as metal halide, mercury vapor, or high-pressure sodium fixtures.
Is the QOB115HID rated for switching duty?
Yes, this breaker is SWD rated. It can be safely used to switch 120V fluorescent lighting circuits on and off on a regular basis without degrading the contacts.
Does the QOB115HID feature a visual trip indicator?
Yes, it includes the Square D Visi-Trip indicator. When the breaker trips, a highly visible red indicator appears, allowing for rapid fault identification in the panelboard.
What wire sizes are accepted by the terminals on the QOB115HID?
The pressure plate terminals accept 14 AWG to 8 AWG wire and are compatible with both aluminum and copper conductors.
How does a QOB breaker install into the panelboard?
QOB breakers feature a bolt-on mounting style. They are secured directly to the panelboard busbar using a screw, which provides a secure connection that will not accidentally dislodge during maintenance.
What type of trip mechanism does the QOB115HID use?
It utilizes a thermal magnetic trip mechanism with fixed long-time and instantaneous trip functions to protect against both sustained overloads and sudden short circuits.
