Product FAQs
7 answersWhich panelboards are compatible with the HFD2050 breaker?
This F-frame breaker is designed for use in Eaton Series C panelboards, motor control centers, and switchboards. It requires a bolt-on connection.
What is the difference between the FD2050 and the HFD2050?
The HFD2050 is the high-interrupting version of the standard FD2050. While both share the same physical dimensions and 50A rating, the HFD2050 provides a higher interrupting capacity of 65kAIC at 480VAC compared to the 35kAIC rating of the FD2050.
Can the HFD2050 be used in DC applications?
Yes, this breaker is rated for DC systems up to 250VDC, with an interrupting capacity of 22kAIC at 250VDC.
What wire sizes are compatible with the HFD2050 lugs?
The standard lugs on this breaker accept wire sizes from 14 AWG up to 1/0 AWG. The terminals are rated for both copper and aluminum conductors.
Is the HFD2050 a direct replacement for older Westinghouse HFD breakers?
Yes, Eaton acquired the Cutler-Hammer and Westinghouse breaker lines. The current Eaton Series C HFD2050 is a direct, drop-in replacement for older Westinghouse or Cutler-Hammer breakers with the exact same catalog number.
What does the LI trip function mean on this breaker?
The LI designation indicates that the thermal-magnetic trip unit includes Long-Time and Instantaneous protection. The Long-Time function protects against sustained overloads, while the Instantaneous function provides immediate tripping during short circuits. Both settings are fixed on this model.
Is there an ultra-high interrupting alternative to the HFD2050?
Yes, if your system requires an interrupting capacity higher than 65kAIC at 480VAC, the FDC2050 is the ultra-high interrupting version, offering up to 100kAIC at 480VAC within the same F-frame footprint.
