Description
Engineered for commercial power distribution, the Square D Q13351021 provides robust thermal-magnetic overcurrent protection. This 35A, three-pole breaker is built to handle demanding electrical loads safely. It installs into legacy Square D Q1 panelboards using a standard plug-on mounting style. For modern upgrades, this specific frame is replaced by the QO3351021 model. Rated at 10 kAIC at 240VAC, it includes a 120/208/240VAC shunt trip for remote tripping and a Visi-Trip indicator.Specifications

Product FAQs
4 answersIs the Q13351021 circuit breaker compatible with modern Square D QO load centers?
No, the Q13351021 is built on the legacy Q1 frame, which is physically wider than modern QO breakers. It is designed specifically for older Square D Q1 panelboards and compatible metering equipment, and will not fit in a standard QO load center.
What does the 1021 suffix indicate on the Q13351021 catalog number?
In Square D nomenclature, the 1021 suffix indicates that the circuit breaker includes a factory-installed 120/240VAC shunt trip accessory. This allows for remote tripping of the breaker in automated control applications.
Can I use a modern QO series circuit breaker to replace the Q13351021?
While QO breakers have largely superseded the Q1 series, the legacy Q1 frame is physically wider. You must verify that your specific Q1 panelboard can accept the narrower QO footprint before attempting a substitution. In many older enclosures, a direct Q1 replacement is required for a proper physical fit.
How can I tell if the Q13351021 circuit breaker has tripped?
The Q13351021 features a Visi-Trip indicator. When the breaker trips due to an overload or short circuit, the handle moves to a center position and a highly visible red indicator appears, allowing for quick fault identification in the panelboard.
