Product FAQs
7 answersWhat does the H08 suffix mean on the Eaton HFD2050H08?
The H08 suffix indicates the breaker is factory-modified for marine compliance under UL 489 Supplement SA. It replaces standard aluminum terminals with corrosion-resistant materials and includes marine-specific labeling for shipboard environments.
Can I use aluminum wire with the HFD2050H08 marine breaker?
No. Because it is modified for marine applications under UL 489 Supplement SA, the HFD2050H08 uses corrosion-resistant terminals that are not rated for aluminum conductors. You must use copper wire sized between 14 AWG and 1/0 AWG.
Which panelboards accept the HFD2050H08 breaker?
This Series C F-frame breaker is designed for use in Eaton, Cutler-Hammer, and legacy Westinghouse Pow-R-Line panelboards and switchboards configured for bolt-on F-frame breakers.
What is the ambient calibration temperature for the HFD2050H08?
As a marine-rated breaker under UL 489 Supplement SA, it features standard thermal calibration at 40 degrees Celsius.
Can the HFD2050H08 replace older Westinghouse HFD breakers?
Yes. Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines. The HFD2050H08 is a direct replacement for legacy Westinghouse and Cutler-Hammer HFD-frame 50A, 2-pole marine breakers.
How does the HFD2050H08 mount into the panelboard?
It is a bolt-on molded case circuit breaker. It secures directly to the panelboard bus using mounting screws, providing a rigid connection that is ideal for high-vibration marine and industrial environments.
What type of trip unit is installed in the HFD2050H08?
It features a non-interchangeable thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) trip functions to protect against overloads and short circuits.
