Mersen Ferraz Shawmut 30322R Fuse Block – 30A, 600V, 2-Pole, Class CC (Rejection Style), Pressure Plate Terminals

The 30322R features a physical rejection pin in the fuse clips. Class CC fuses have a unique grooved cap on one end; this block will only accept that specific fuse type. This safety feature prevents a technician from accidentally installing a standard midget fuse (which has lower interrupting ratings) into a circuit that requires the high current-limiting performance of Class CC.
