Product FAQs
5 answersWhat is the primary application for the Q2M2225MT breaker?
This 225A Q2M frame breaker is engineered specifically for use as a tenant main circuit breaker in Square D EZ Meter-Pak multi-metering centers.
Can I use a QO adapter kit instead of this Q2M breaker?
Square D EZ Meter-Pak adapter kits, such as the EZM125QOA, allow QO breakers to fit in Q2M spaces but are limited to 125A maximum. For a 225A service, you must use a dedicated Q2M frame breaker like the Q2M2225MT.
What type of protection does the LI trip unit provide?
The LI designation indicates a thermal-magnetic trip unit equipped with fixed Long-Time overload protection and fixed Instantaneous short-circuit protection. This trip unit is factory sealed and non-interchangeable.
What are the acceptable wire sizes for the terminals on this breaker?
The terminal connections are rated to accept either aluminum or copper conductors ranging from 4 AWG to 300 kcmil.
How does this breaker connect to the meter center bus?
The Q2M2225MT features a bolt-on mounting style and uses stud or tapped pad connections to securely fasten directly to the EZ Meter-Pak bus assembly.
