ZK2.5-SF PI-Spring terminal blocks
For 5x20 fuses - 6 mm 0.236 in spacing

2.5 mm² Description
12 AWG
Protect your circuits with 5x20 fuse terminal blocks compliant with IEC 60947-7-3 standard (fuse not sup-
2 plied with the terminal blocks),

ZK2.5-SF –– Simplify the distribution thanks to the 2 jumper channels aligned with ZK4-3P feed-through and ZK2.5-S-R1
disconnect terminal blocks.
