Description
Built for demanding environments, the Eaton HFD1020J01 features a specialized moisture and fungus treatment.

Product FAQs
6 answersWhat does the "J01" suffix mean on the Eaton HFD1020J01?
The "J01" suffix indicates that the circuit breaker has received a factory moisture and fungus treatment. This makes the breaker fungus proof, which is ideal for marine applications, tropical environments, or other high humidity installations.
What equipment is the HFD1020J01 F-Frame breaker compatible with?
This breaker is designed for use in Eaton Series C panelboards, switchboards, motor control centers, and busway systems. It mounts using a standard bolt-on connection.
What type of wire can be used with the HFD1020J01 terminals?
The factory installed cable-in/cable-out lugs accept 14 AWG through 1/0 AWG conductors. The terminals are dual rated for both copper (Cu) and aluminum (Al) wire.
Can the trip settings be adjusted on the HFD1020J01?
No, this breaker features a non-interchangeable, fixed thermal magnetic trip unit. Both the long-time (overload) and instantaneous (short-circuit) trip functions are factory set and cannot be modified in the field.
Is the HFD1020J01 suitable for switching lighting loads?
Yes, as a 20-amp, 1-pole breaker, it carries an SWD (Switching Duty) rating, meaning it is approved for switching fluorescent lighting circuits on and off on a regular basis. It is also HID (High-Intensity Discharge) and HACR rated.
Can the HFD1020J01 be reverse fed?
Yes, Eaton Series C F-Frame thermal magnetic breakers like the HFD1020J01 do not have line and load restrictions, making them suitable for reverse feed applications.
