This datasheet provides detailed information on the ZS4-R1 screw clamp terminal block.
The ABB ZS4-R1 is a screw‑clamp feed‑through terminal block with an 8 mm (0.375 in) spacing and a 4 mm² (10 AWG) rated cross‑section. It features a polyamide insulating material, UL94 VO flammability rating, and IP20 protection, making it suitable for a variety of wiring and fuse circuit applications.
The terminal block is rated for up to 800 V (IEC) / 300 V (UL/CSA) and a continuous current of 24 A. It can withstand short‑time surge currents of 480 A (1 s) and operates within a storage temperature range of –55 °C to +110 °C. Environmental testing includes dry heat at +100 °C for 96 h and cyclic damp‑heat cycles, ensuring reliable performance in harsh conditions.
