Square D QOB220SWN 2 Pole Bolt-on Circuit Breaker 20A

Product Description

The SQUARE D QOB220SWN is a 2-pole, bolt-on miniature circuit breaker rated at 20 amps and 120 volts AC. It provides overcurrent and short-circuit protection in panelboard applications where a secure, bolt-on mount is required. The pressure plate terminal connection accepts 14 to 8 AWG wire, making it suitable for branch circuit work in commercial and light industrial settings. Licensed electricians install this breaker as part of new panelboard builds or as a direct replacement in existing Square D NQOD panelboard assemblies. It carries UL Listed and CSA certifications and is RoHS compliant.

This breaker is designed for use in Square D NQOD panelboards and is a common replacement component in commercial electrical distribution systems. The bolt-on mounting style ensures a firm, vibration-resistant connection in high-demand environments. Its compact form factor fits standard breaker slots without modification, making it a straightforward swap during panel upgrades or service calls where a 2-pole, 20-amp bolt-on position is required.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panelboard and verify the absence of voltage before installing or removing any circuit breaker. Confirm that the wire gauge used falls within the 14 to 8 AWG range supported by the pressure plate terminals. Do not exceed the breaker's rated ampacity when sizing the branch circuit load.
