Operating as a core component in industrial power distribution, this 200A breaker offers fixed thermal and magnetic trip functions. Installation into Square D I-Line panelboards is streamlined by the integrated AB phase connection. Electrical contractors frequently utilize this model as a substitute for the obsolete Q22200AB. Capable of interrupting 65kA at 240V, the unit provides substantial short-circuit protection and incorporates Square D's signature Visi-Trip mechanism.
What type of panelboards is the QGA222001 compatible with?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards. It utilizes a specific plug-in mounting bracket and will not fit in standard NQ, NF, or QO load centers.
What does the 1 suffix in the QGA222001 catalog number indicate?
The 1 at the end of the catalog number specifies that this 2-pole breaker is configured for an AB phase connection on the I-Line bus stack.
Can the QGA222001 replace older Square D circuit breakers?
Yes, electrical contractors frequently use the QGA222001 as a direct, modern replacement for the obsolete Q22200AB I-Line circuit breaker.
What does the G in the QGA222001 catalog number signify?
In the Square D PowerPacT Q-Frame series, the G designates the interrupting capacity tier. It indicates that the breaker has a high interrupting rating of 65kAIC at 240V AC.
How are connections made on the QGA222001?
The line side features an I-Line plug-in jaw that snaps directly onto the panelboard bus stack, eliminating the need for line-side wiring. The load side utilizes mechanical lugs that accept 4 AWG to 300 kcmil aluminum or copper conductors.
Are the trip settings on the QGA222001 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time overload and instantaneous short-circuit protection settings are factory fixed and cannot be adjusted in the field.
