Product FAQs
5 answersWhat panelboards accept the Eaton EHD1070 breaker?
This F-Frame breaker bolts directly into Eaton and Cutler-Hammer Series C panelboards, switchboards, and motor control centers. It is not interchangeable with panels from other manufacturers like Square D or Siemens.
Can the EHD1070 replace legacy Cutler-Hammer FDB1070 or FD1070 breakers?
Yes, the EHD1070 shares the same F-Frame footprint and mounting dimensions as the FDB1070 and FD1070, making it a physical drop-in replacement. However, always verify that the EHD1070 interrupting rating meets or exceeds the available fault current at your installation point, as the original FD breaker may have had a higher AIC rating.
Can the EHD1070 be reverse fed?
Yes, this thermal-magnetic Series C breaker features a trip-free mechanism and is rated for reverse feed applications.
Is the EHD1070 suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment requiring 70A overcurrent protection.
Can I use standard Series C accessories with the EHD1070?
Yes, the EHD1070 shares the standard F-Frame footprint, meaning it is compatible with common Series C internal accessories like shunt trips, auxiliary switches, and undervoltage releases.
