ZS4-D2 screw clamp terminal block can connect 4 mm² (CB certified) 12 AWG conductors, save space and has high wiring density and double deck design.
The ZS4-D2 is a double‑deck screw clamp terminal block designed for high wiring density. It accepts rigid or flexible conductors up to 4 mm (CB certified) in a 0.205 in spacing and provides a rated current of 29 A (IEC 60947‑7‑1). The block features IP20 protection, polyamide insulating material, and a recommended tightening torque of 0.6 Nm.
The datasheet lists ordering codes for grey, blue and orange versions, environmental test results (temperature range –5 °C to +40 °C for installation, –55 °C to +110 °C storage), short‑circuit current ratings (480 A for 1 s), and a range of accessories such as end stops, jumper bars and test adapters. Additional technical details include short‑circuit current rating (SCCR), dielectric test voltage, and compliance with IEC, UL, CSA and ATEX standards.
