These switches have a maximum voltage rating of 48V DC, a continuous current rating of 300A, an intermittent rating of 500A for 5 minutes, and a cranking rating of 900A for 30 seconds. They accept cables up to 4/0 AWG for optimal performance and in fact these cables are required to meet the ratings. The cable is used to help remove heat from the switch.
