Yes, this 100A breaker is HACR rated, making it suitable for overcurrent protection in heating, air conditioning, and refrigeration equipment circuits.
How does the BAB2100H connect to the panelboard busbar?

We placed our first order with superbreakers.com recently for a breaker we weren't able to acquire locally. I ordered the breaker way ahead of time because I've had issues with shipping for products purchased online in the past. The estimate for the item when I initially ordered was 3 days. Without adding an expedited shipping options, the breaker arrived the next day. We installed it this week, and so far so good. In my opinion, they sell quality parts and have excellent turn around time. Very impressed.
