ZK2.5-SF-R PI-Spring terminal blocks
For 5x20 fuses - with blown fuse indicator - 6 mm 0.236 in spacing

Description
2.5 mm²
– Protect your circuits with 5x20 fuse terminal blocks compliant with IEC 60947-7-3 standard (fuse not sup-
12 AWG plied with the terminal blocks),
– Simplify the distribution thanks to the 2 jumper channels aligned with ZK4-3P feed-through and ZK2.5-S-R1
disconnect terminal blocks,
– Quickly identify the defective circuit thanks to the blown fuse indicator (with leakage current < 0.5 mA).

The fuse holder must be first disconnected prior any fuse replacement. Mount your fuse safely without touching
any active part: put the fuse into the hooks of the fuse holder shutter; at the closing of the shutter, the fuse is
24.6 0.97" perfectly in place in the fuse holder.
