Product FAQs
8 answersWhich enclosures accept the EHC2030 circuit breaker?
The EHC2030 is a bolt-on F-frame breaker designed specifically for Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It is not compatible with standard load centers that require plug-on breakers.
How does the EHC2030 compare to other Eaton F-frame breakers?
The EHC2030 shares the exact physical dimensions and mounting footprint as other Series C F-frame breakers, such as the EHD, FD, and HFD models, allowing for direct physical replacement in compatible enclosures.
Is the EHC2030 suitable for reverse feed applications?
Yes. Eaton Series C F-frame circuit breakers feature standard thermal-magnetic trip units that allow for reverse feeding without compromising the protection ratings.
How is the EHC2030 applied in DC systems?
While rated for 250VDC, proper application in direct current systems often requires wiring the poles in series. The exact wiring configuration depends on whether the DC system is grounded or ungrounded. Always consult Eaton F-frame DC wiring diagrams for safe installation.
Can internal accessories be field-installed in the EHC2030?
No. Eaton Series C F-frame circuit breakers are factory-sealed. Opening the breaker to field-install internal accessories like shunt trips, undervoltage releases, or auxiliary contacts will void the UL listing. These accessories must be factory-installed.
Is the EHC2030 HACR rated?
Yes. All Eaton Series C F-frame circuit breakers are HACR rated, making them suitable for protecting heating, air conditioning, and refrigeration motor circuits.
Can the EHC2030 be used for switching high intensity discharge (HID) lighting?
Yes. Eaton Series C F-frame breakers rated from 10A to 50A are marked as suitable for HID lighting applications, allowing this 30A breaker to safely switch these specific lighting loads.
Are the trip settings adjustable on the EHC2030?
No. This breaker features a fixed thermal and fixed magnetic trip unit. Neither the long-time nor the instantaneous trip functions can be adjusted in the field.
