The Square D 1200A Heavy Duty Safety Switches will accept Class L fuses ONLY and the range of amperage according to the Fuse Manufactures charts range from 601 A up to 1200A Maximum.

If a Fuse Manufacture makes a CLASS L fuse that is physically the same dimensions as the standard 601A to 1200amp fuse, but less than 601amps, then it would work in the switch.
2) DO NOT USE RENEWABLE LINK FUSES IN SQUARE D SAFETY SWITCHES. The use of renewable link fuses may adversely affect user safety, impair reliability and will void the warranty.
