Product FAQs
5 answersWhat do the "AA" and "SA" suffixes indicate on the HDL36125AASA?
The "AA" suffix denotes a factory-installed 1A/1B standard auxiliary switch for remote status signaling, and the "SA" suffix indicates a factory-installed 120VAC shunt trip for remote tripping capabilities.
How is the HDL36125AASA circuit breaker mounted?
This is a unit-mount (feed-thru) breaker. It bolts directly to the backpan of industrial control panels, switchboards, or PowerPacT H-Frame enclosures rather than plugging onto a busbar.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal and fixed magnetic trip unit provides standard LI (Long-Time and Instantaneous) functions, protecting against everyday overloads and high-level short circuits.
Is this breaker suitable for DC control circuits?
Yes, the HDL36125AASA is rated for up to 250VDC (at 20kAIC), making it compatible with industrial battery systems and DC control panels.
What wire sizes are compatible with the factory lugs?
The included lugs accept 14 AWG to 3/0 AWG aluminum or copper conductors. Always verify proper torque requirements per Schneider Electric's installation guidelines.
