Overview

The ABB LD38-4 (SKU: LD38-4) is a 3-pole additional terminal block specifically designed for ABB AF26 through AF38 series 3-pole contactors. This block enhances the connecting capacity of these contactors and facilitates pre-wiring, streamlining installation and ensuring secure connections. The LD38-4 features reliable tunnel terminals for robust electrical connections. Engineered for industrial applications, the LD38-4 offers a rated insulation voltage (Ui) of 690 V according to IEC 60947-4-1 and 600 V according to UL/CSA standards. It is suitable for environments with a pollution degree of 3. The main terminals utilize screw connections with a double connector design, accommodating a wide range of conductor sizes: * **Rigid solid conductors (≤ 4 mm²):** 1x 2.5 to 25 mm² * **Stranded conductors (≥ 6 mm²):** 1x 2.5 to 25 mm² + 1x 2.5 to 16 mm² * **Flexible conductors with non-insulated ferrules:** 1x 2.5 to 16 mm² (or 1x 2.5 to 16 mm² + 1x 2.5 to 10 mm²) * **Flexible conductors with insulated ferrules:** 1x 2.5 to 16 mm² (or 1x 2.5 to 16 mm² + 1x 2.5 to 10 mm²) * **UL/CSA compliance:** 1x AWG 8-4 or 2x AWG 8-6 The LD38-4 requires a stripping length of 14 mm and a tightening torque of 2.5 Nm (22 lb.in). It provides an IP20 degree of protection according to IEC/EN 60947-1 and IEC/EN 60529, protecting against solid objects larger than 12.5 mm. The M5 main terminals are compatible with Flat Ø 6.5 / Pozidriv 2 screwdriver types. Please note that the utilization of LD38-4 additional terminal blocks does not permit the use of BER and BEY connection sets. Each package contains 2 units.
