Product FAQs
7 answersWhat does the "-1212" suffix indicate on the FHL36050-1212?
The "-1212" suffix designates a factory-installed 1A/1B (one normally open, one normally closed) auxiliary switch, which provides remote status signaling for the breaker.
What is the modern replacement for the legacy FHL36050-1212?
For modern system upgrades, this legacy F-Frame breaker is typically replaced by a PowerPact H-Frame breaker, such as the HGL36050, which requires a retrofit kit for installation in older equipment.
What equipment is compatible with the FHL36050-1212?
This unit-mount breaker is designed for installation in standard Square D enclosures, switchboards, and motor control centers.
What wire sizes are supported by the lugs on the FHL36050-1212?
The standard lugs accept 14 to 1/0 AWG copper conductors or 12 to 1/0 AWG aluminum conductors.
Is the FHL36050-1212 suitable for direct current systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, delivering a 10kA interrupting capacity.
How is the FHL36050-1212 installed in a panel?
This is a feed-thru, unit-mount breaker. It bolts directly to the mounting surface or enclosure backpan rather than plugging into a busbar system.
How does the thermal-magnetic trip unit operate on this breaker?
The breaker uses fixed thermal and fixed magnetic elements to provide Long-Time and Instantaneous (LI) protection against overloads and short circuits.
