This probably has an obvious answer:eek:

Are there any physical differences between an Eaton FD3060 breaker and a HD3060 breaker. Is the frame exactly the same size and mounting dimension
Is there a difference in the trip mechanism.?

I assume there is some difference in the kaic rating, but that i can see from the label.

Physically speaking, no. They both will bolt into their Distribution Centers with the same buss kit, and the panel cover fits as it always would. However, as mentioned above, there are some electrical differences. The "H" is a prefix for "High Rupture Capacity" which is often times needed for 600vac circuits like we have in Canada.
