These finger-safe fuse blocks are compatible with midget fuses sized at 10mm x 38mm (13/32" x 1-1/2") and rated up to 30A. They work with the midget fuses to supplement the primary branch-circuit fuse or breaker and provide backup overcurrent protection for lighting, solenoid, motor, and transformer circuits.
