Product FAQs
7 answersWhat enclosures are compatible with the Q1L230?
This breaker is designed specifically for legacy Square D Q1L enclosures and compatible OEM panels that accept Q-Frame unit-mount breakers.
What wire sizes are supported by the lugs on the Q1L230?
The factory-installed lugs accommodate wire gauges from 14 AWG to 8 AWG, and are rated for both aluminum and copper conductors.
How is the Q1L230 installed in an electrical system?
It utilizes a standalone unit-mount design with a feed-thru connection. This allows the breaker to be independently mounted and wired directly, rather than plugging or bolting onto a traditional panel busbar.
Can the Q1L230 be used on a standard 120/240V system?
Yes. While rated for a maximum of 240VAC, this two-pole breaker is fully compatible with standard 120/240V single-phase electrical systems.
What is the maximum fault current the Q1L230 can safely interrupt?
This breaker has an interrupting capacity of 10kAIC at 240VAC, making it suitable for applications where the available fault current does not exceed 10,000 amps.
Is the Square D Q1L230 still actively manufactured?
The Q1L series is a legacy product line. Facilities looking to modernize their infrastructure often utilize the Square D QOU series as a functional unit-mount substitute.
How does the Q1L230 protect against electrical faults?
It features a fixed thermal-magnetic trip unit. The thermal element provides long-time protection against gradual overloads, while the magnetic element offers instantaneous tripping during severe short circuits.
