Product FAQs
5 answersIs the Square D A1L360 still manufactured, or is there a direct replacement?
The A1L360 is a legacy circuit breaker. The modern direct replacement is the Square D QOU360, which shares the same 60A, 3-pole configuration and unit-mount design.
How is the A1L360 circuit breaker mounted?
This breaker features a feed-thru design, meaning it is typically surface-mounted or DIN rail-mounted in OEM panels and control enclosures rather than plugging or bolting onto a standard panelboard bus.
What applications are best suited for the A1L360?
Due to its feed-thru connection, it is commonly used in OEM equipment, control panels, and custom enclosures where a dedicated mounting base is utilized instead of a standard distribution panelboard.
Can the A1L360 be used in DC applications?
Yes, in addition to its 240VAC rating, this breaker is rated for up to 48VDC, making it suitable for specific low-voltage DC control circuits.
What type of protection does the A1L360 thermal magnetic trip unit provide?
The thermal magnetic mechanism provides dual protection. The thermal component offers long-time response for sustained overloads, while the magnetic component provides instantaneous tripping for short-circuit faults.
