Product FAQs
7 answersWhat does the "L" in the HFD1050L catalog number signify?
The "L" suffix indicates that the circuit breaker is supplied with factory-installed line and load lugs. Without this suffix, the breaker would be supplied with standard terminal pads only.
What is the difference between the Eaton FD1050L and HFD1050L?
The HFD1050L is the high-interrupting capacity version of the standard FD1050L. While both are 50A, 1-pole Series C F-frame breakers, the HFD model provides a higher interrupting rating of 100kAIC at 240VAC, whereas the standard FD model has a lower short-circuit rating.
Can I install the HFD1050L in a standard residential load center?
No. The HFD1050L is a Series C F-frame molded case circuit breaker designed specifically for commercial and industrial Eaton panelboards and switchboards. It will not fit in standard BR or CH residential load centers.
Is the HFD1050L rated for use in DC power systems?
Yes, this thermal-magnetic circuit breaker is rated for direct current applications and provides an interrupting capacity of 10kA at 125VDC.
What type of trip unit is installed in the HFD1050L?
This breaker features a fixed thermal, fixed magnetic (LI) trip unit. It provides non-adjustable long-time overload protection and instantaneous short-circuit protection.
Does the HFD1050L come with mounting hardware?
No, Eaton Series C F-frame unit-mount breakers do not include mounting hardware. You will need to reuse your existing hardware or procure the correct screws for your specific panelboard or enclosure.
What is the modern Eaton replacement for the Series C HFD1050L?
Eaton has designated the Power Defense Frame 2 (PDG2) series as the modern successor to the Series C F-frame. A 1-pole, 50A Power Defense breaker with equivalent interrupting ratings can replace the HFD1050L, though updated mounting hardware is required.
