Product FAQs
5 answersWhich panels and metering centers accept the Q2M2100VH breaker?
This bolt-on breaker is specifically designed to mount into Square D Meter-Pak, EZM Metering centers, and NQOD panelboards.
What is the modern replacement for the legacy Q2M2100VH?
For new installations or system upgrades, the Q2M2100VH has been superseded by the PowerPact Q-Frame QDM22100TN. The QDM22100TN provides the same 100A rating and physical footprint but offers an upgraded 25kAIC interrupting capacity.
What wire sizes are compatible with the Q2M2100VH terminals?
The included lugs accept either aluminum or copper wiring ranging from 4 AWG up to 300 kcmil.
How does the trip mechanism function on the Q2M2100VH?
It features a fixed thermal-magnetic trip unit. The thermal component provides long-time protection against sustained overloads, while the magnetic component offers instantaneous protection against short circuits.
Can I use QO breakers in place of a Q2M breaker in an EZ Meter-Pak?
Yes, but it requires a specific adapter kit, catalog number EZM125QOA. This adapter allows standard QO breakers to be installed in the bolt-on spaces normally reserved for 2-pole Q2M tenant breakers up to 125A.
