Product FAQs
8 answersWhat panelboards are compatible with the HFD2040 circuit breaker?
The HFD2040 is designed for use in Eaton Series C panelboards, switchboards, and motor control centers that accept F-frame bolt-on breakers.
Can the HFD2040 replace a standard FD2040 breaker?
Yes. The HFD2040 shares the same physical dimensions and F-frame mounting footprint as the FD2040, but it offers a higher interrupting capacity of 65kAIC at 480VAC compared to the 35kAIC rating of the standard FD2040.
What is the modern Power Defense replacement for the HFD2040?
When transitioning to newer Eaton systems, the HFD2040 is typically replaced by the Power Defense PDG22M0040TFFL molded case circuit breaker.
Can the HFD2040 be mounted on a standard DIN rail?
No. The HFD2040 is a bolt-on molded case circuit breaker designed for direct installation into panelboards, switchboards, or standalone F-frame enclosures. It is not designed for DIN rail mounting.
Is the HFD2040 suitable for direct current (DC) applications?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 22kAIC. When installing in DC systems, follow Eaton guidelines for wiring poles in series based on the specific system voltage and grounding configuration.
Does the HFD2040 provide ground fault or arc fault protection?
No. The HFD2040 features a standard thermal-magnetic trip unit that provides long-time overload and instantaneous short-circuit protection. It does not include GFCI or AFCI circuitry.
What wire sizes are accepted by the standard lugs on the HFD2040?
The standard line and load lugs on this breaker accept wire gauges from 14 AWG up to 1/0 AWG, and they are compatible with both copper and aluminum conductors.
What does the LI trip function code mean on the HFD2040?
The LI designation indicates that the breaker's thermal-magnetic trip unit provides Long-Time (L) protection for sustained overloads and Instantaneous (I) protection for immediate short-circuit faults. Both trip settings are fixed on this model.
