Product FAQs
4 answersWhat equipment is the Square D Q2M3200MT designed to fit?
This bolt-on circuit breaker is commonly used as a main or tenant breaker in Square D EZM Metering centers, Meter-Pak enclosures, and NQOD panelboards.
Is the Q2M3200MT still actively manufactured?
The Q2M3200MT is a legacy circuit breaker. For new installations or system upgrades, Schneider Electric generally recommends transitioning to the modern PowerPact Q-Frame series. Always verify dimensional clearances and interrupting ratings when selecting a modern replacement.
How do you reset the Q2M3200MT after an overcurrent trip?
When a fault occurs, the breaker handle will snap to a middle position between ON and OFF. To reset it, firmly push the handle completely to the OFF position to reset the internal mechanism, then switch it back to the ON position.
Can the Q2M3200MT be used in a 480V commercial distribution system?
No. The Q2M3200MT is strictly rated for a maximum of 240VAC. Applying it to a 480V system exceeds its physical design limits, negates its 10kAIC interrupting rating, and violates safety codes.
