These finger-safe fuse blocks house fuses for overcurrent protection and include a disconnect switch for manually opening and closing a circuit when changing fuses or performing maintenance on the circuit. Also called compact circuit protectors (CCP), they are 2/3 the size of a typical fused switch holder to save space in industrial control panels, machinery electrical panels, and HVAC equipment. They're installed on main, branch, or supplementary (backup) circuits depending on the fuse type. These fusible disconnect switch blocks mount on a 35mm DIN rail and have a visual indicator to make it easier to identify blown fuses for replacement.Finger-safe fuse blocks are IP20-rated blocks that enclose fuses to protect against accidental contact with live wires, clips, and terminals. They provide touch-safe operation without requiring a separate cover and are more compact than open fuse blocks to save installation space. These fuse blocks allow tool-free fuse changes to speed replacement of blown fuses.
