Product FAQs
5 answersWhat does the BC suffix in the Q221200BC catalog number indicate?
The BC suffix designates the phase connection. This specific breaker is configured with plug-on jaws that connect exclusively to the B and C phases on the bus stack of a Square D I-Line panelboard.
Is the Q221200BC a current production breaker?
No, this is a legacy Q-frame circuit breaker. For system upgrades or new installations requiring a 200A, 10kAIC I-Line breaker, it is typically superseded by the modern PowerPact Q-frame equivalent, base catalog number QBA22200 (specific phase connection suffixes will apply).
How can I visually identify if this breaker has tripped?
The Q221200BC features a Visi-Trip indicator. When a fault causes the breaker to trip, the handle moves to a center position and a highly visible red indicator appears in the window, allowing for quick identification in a crowded panel.
Are the thermal and magnetic trip settings adjustable on this model?
No. This breaker utilizes a standard thermal-magnetic trip unit with fixed long-time and fixed instantaneous trip functions. It does not offer adjustable dials for customizing the trip curve.
Does the Q221200BC require a separate mounting bracket kit?
No. Like all I-Line style circuit breakers, it features integrated plug-on jaws and a mounting bracket that attach directly to the panelboard bus and backpan. No additional mounting hardware kits are required for installation.
