Product FAQs
6 answersWhich panelboards are compatible with the Square D Q1370 circuit breaker?
The Q1370 is a plug-on molded case circuit breaker designed specifically for use in legacy Square D Q1 and NQO panelboards.
What is the modern replacement for the legacy Q1370 breaker?
While the Q1370 is used to maintain existing Q-Frame infrastructure, Square D designates the QO370 as the modern replacement. Installing a QO series breaker in an older NQO or NQOB panelboard requires a specific mounting assembly kit, such as the SK5668 or SK5669.
How is the Q1370 mounted into the panelboard?
The Q1370 features a plug-on mounting style for direct installation into compatible Q1 and NQO panelboard busbars.
Does the Q1370 provide a visual indication when tripped?
Yes, the breaker features a visual trip indicator window that allows electricians and maintenance personnel to quickly identify a tripped circuit during a fault event.
What wire gauge range is supported by the Q1370 terminals?
The breaker lugs accept both aluminum and copper wiring, accommodating wire sizes from 8 AWG up to 2 AWG.
What type of protection does the Q1370 trip unit provide?
It features a fixed thermal-magnetic trip unit with Long-Time and Instantaneous (LI) functions, providing reliable protection against both sustained overloads and sudden short circuits.
