Product FAQs
8 answersCan I install the QOB210 in a standard QO load center?
No. The QOB210 features a bolt-on connection designed specifically for NQ and NQOD panelboards. Standard QO load centers require plug-on QO breakers.
Is the Square D QOB210 HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment motor group combinations.
How does the QOB210 mount to the panel bus?
It uses a bolt-on connection that secures directly to the busbar of NQ or NQOD panelboards. This provides a secure mechanical and electrical connection that is ideal for commercial and industrial environments.
Is there a 22kAIC version of the 10A QOB breaker?
No. Square D QOB-VH breakers, which offer a 22kAIC rating, start at 15 amps. The 10-amp QOB210 is only available with a standard 10kAIC rating.
Does Square D manufacture a 10A QOB breaker with ground fault (GFI) protection?
No. Square D QOB-GFI and QOB-EPD breakers are only manufactured in 15-amp ratings and higher. If a 10-amp circuit requires ground fault protection, it must be provided by a separate device.
Are 1-pole and 3-pole versions of this 10A breaker available?
Yes. The 10-amp QOB series is also available in a 1-pole configuration (QOB110) and a 3-pole configuration (QOB310).
Is the QOB210 SWD (Switching Duty) rated for fluorescent lighting?
No. Square D SWD ratings for switching 120VAC fluorescent lighting loads apply only to 15-amp and 20-amp QO and QOB breakers.
Is this breaker HID rated for high-intensity discharge lighting?
No. Square D QOB-HID breakers are only available in 15-amp to 50-amp ratings. The 10-amp QOB210 does not carry an HID rating.
