Product FAQs

4 answers
What does the HID designation mean on the QOB240HID circuit breaker?

The HID suffix indicates the breaker is rated for switching high-intensity discharge lighting circuits. These lighting systems, such as metal halide or mercury vapor, generate high inrush currents that standard breakers may not reliably handle.

Can I install the QOB240HID in a standard plug-on QO load center?

No. The QOB240HID features a bolt-on mounting design. While it belongs to the QO series family, it requires a bolted connection to the bus bar and is specifically designed for NQ and NQOD panelboards, or QOB load centers.

How can I tell if the QOB240HID has tripped?

This breaker features the Square D Visi-Trip indicator. When a fault occurs and the breaker trips, a highly visible red flag appears in the indicator window, allowing you to quickly locate the tripped circuit in a crowded panel.

What type of trip functions does the QOB240HID utilize?

This thermal-magnetic breaker utilizes both long-time and instantaneous trip functions. The long-time function protects against sustained overloads, while the instantaneous function provides an immediate response to severe short circuits.
