Information from Schneider Electric - history of HACR
http://ecatalog.squared.com/pubs/Ci...Case%20Circuit%20Breakers/0600DB0102.pdf"...additional investigation was done including tests to determine that the circuit breaker provided appropriate protection for the circuit components of typical heating, air conditioning, and refrigeration equipment."
"It was found that all circuit breakers that passed the normal UL 489 tests also passed the special HACR testing without a special design."
