Product FAQs
5 answersWhat equipment is compatible with the Q2L32175 circuit breaker?
This legacy Q-frame breaker is designed for installation in Square D individual enclosures, switchboards, and legacy NQOD panelboards.
Can a modern PowerPact QB breaker replace the Q2L32175?
While modern PowerPact Q-frame breakers (such as the QBL series) physically fit, using the exact legacy Q2L32175 preserves the original UL listing of legacy NQOD panelboards.
How is the Q2L32175 mounted?
It is a unit-mount, feed-thru circuit breaker. It secures directly to the enclosure or panelboard rather than plugging onto a bus, utilizing mechanical lugs on both the line and load sides.
What wire sizes are accepted by the terminals on this 175A breaker?
The standard lugs accommodate either aluminum or copper conductors ranging from 4 AWG to 300 kcmil.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic trip unit delivers standard LI protection, combining long-time thermal response for overloads with an instantaneous magnetic response for short circuits.
