Product FAQs
4 answersWhat does the 2100 suffix indicate on the QO3202100 catalog number?
The 2100 suffix means this breaker includes a factory-installed alarm switch, also known as a bell alarm. The integrated contacts provide remote status indication by activating when a trip event occurs.
How does the alarm switch function differ from a standard auxiliary switch?
The factory-installed alarm switch changes contact state only when the breaker trips due to an overload or short circuit. It does not activate when the breaker is manually toggled on or off, ensuring you only receive notifications for actual fault conditions.
Does the QO3202100 require additional space in the panelboard?
Yes. Because it includes a factory-installed alarm switch, this breaker requires one additional pole space in your QO load center or NQ/NQOD panelboard. It will take up a total of four spaces despite being a three-pole breaker.
How does the visual trip indicator work on this breaker?
This breaker features the standard Square D Visi-Trip design. When the breaker trips, the handle snaps to a midpoint position and a highly visible red indicator appears, allowing you to quickly identify the faulted circuit in a crowded panel.
