I should have been more clear. The label says Max Fuse/Breaker*. There is a side note saying a HACR breaker must be used if compressor protection is not provided.

On these particular units we will provide both compressor fusing and a unit fused disconnect.

Some of our customers try to trim as much cost off the unit price as possible and make up for it on the service end. These units are so large and are sectional that we are going to catalog them with all the protection we can provide.
