ZK16 PI-Spring terminal blocks
Feed-through - 12 mm 0.472 in spacing

Description
16 mm²
Combine high performance with compact dimensions:
4 AWG – 1000 V AC / DC IEC 600 V UL,
– Opt for the best marking visibility thanks to the up-front, flat marker zone, which lets you mark up to eight
digits or increase the font size.
