As per my experience of working as a commissioning engineer that The relay and the contactor have main 3 difference 1. Relay has low current rating while the contactor has high current rating 2. Relay has a single phase operating device while the contactor has three phase operating device 3. Relay has no access to connect multiplier NO/NC "add on" while the contactor has the provisions of connect multiplier NO/NC "add on" in the front of it. But you are not mentioned the 3rd one rather you mentioned some un-important differences like safety features, maintenance etc. The contactor also needs less maintenance and most of the contactor has no safety features.
