Product FAQs
6 answersWhich panelboards are compatible with the Square D Q1350 circuit breaker?
The Q1350 is designed for use in legacy Square D Q1 and NQO panelboards. It features a plug-on mounting style that fits the original spacing of these older enclosures.
What is the modern replacement for the legacy Q1350 circuit breaker?
The Q1 series is a legacy frame that has been replaced by the QO series, specifically the QO350, for modern installations. However, installing a QO breaker in an older Q1 or NQO panelboard requires a specific mounting assembly kit, such as the SK5669. Using the original Q1350 ensures a direct physical fit without adapters.
What are the wiring specifications for the Q1350 terminal lugs?
The breaker is equipped with standard mechanical lugs that accept 8 AWG to 2 AWG wire. The terminals are rated for both aluminum and copper conductors, providing flexibility for existing field wiring.
How does the LI trip function operate on the Q1350?
The LI designation indicates a fixed thermal-magnetic trip unit. The thermal component provides long-time (L) protection against gradual overloads, while the magnetic component delivers instantaneous (I) protection against severe short circuits.
Does the Q1350 feature a visual trip indicator?
Yes, this breaker includes a built-in Visi-Trip indicator. When the breaker trips due to an overload or short circuit, a high-visibility indicator appears, allowing users to quickly identify the faulted circuit.
Does the Q1350 require mounting hardware for installation?
No, the Q1350 features a plug-on connection design. It snaps directly onto the busbar of compatible Q1 and NQO panelboards, requiring no additional bolt-on hardware for the line-side connection.
