Description

Designed to serve as a main breaker, the 200A, three-pole molded case circuit breaker delivers essential long-time and instantaneous (LI) trip functions. It features a Visi-Trip indicator for rapid fault detection and is HACR rated for use with heating and cooling equipment. The unit mounts into Square D commercial panelboards and switchboards, providing a 10kAIC interrupt rating at 240VAC. For newer installations, this model is replaced by the QDL32200, though mounting should be verified.

Product FAQs

5 answers
Which Square D panelboards accept the Q2M3200MB main breaker?

This legacy breaker is primarily installed as a main breaker in older Square D NQOB and NQOD panelboards, as well as compatible Meter-Pak and EZM metering centers.

What is the modern replacement for the Q2M3200MB circuit breaker?

The Q2M series is obsolete. The PowerPact Q-Frame series, specifically models like the QDL32200 or QBM32200TN, often serve as modern replacements. Always verify the specific bus connections and mounting hardware required for your existing panel before substituting.

How are the load side connections configured on this breaker?

The Q2M3200MB features a bolt-on design where the line side uses standard wire lugs, and the load side utilizes threaded studs that bolt directly to the panelboard branch bus.

Can the Q2M3200MB be used to protect HVAC circuits?

Yes, this breaker is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment.

How can I visually identify if the Q2M3200MB has tripped?

This breaker is equipped with a Visi-Trip indicator. When a fault or overload causes the breaker to trip, a highly visible red indicator appears in the window to help quickly locate the tripped circuit.
