DKK series are the DIN rail terminal blocks which are designed for fitting both 35mm and 32mm DIN rails. The series uses steel yoke as the fixture to tighten up the wire connections and the structure offers anti-vibration, prevent from wire loosening, enlarge the contact point and get the highest reliability out of the product. The shape of the whole series is in standard design, which can make the connections in order, clearly, and have the best appearance. The four contacts are divided into two circuits. Each circuit is 1-in-1-out. Rated voltage: UL 300V, IEC 400V. Rated current: UL 20A, IEC 24A. Conductor cross-section, solid (AWG/mm2): UL 22-12, IEC 0.5-2.5. Conductor cross-section, flexible (AWG/mm2): UL 22-12, IEC 0.5-2.5. Rated impulse withstand voltage: 6KV. Torque(N-m): 0.4. Screw: M2.5. Wire strip length: 6mm. Insulating material: PA. TxHxW(mm): 5.1 x 62.8 x 69.4. End cover DDK2.5C. Screw-on bridge DS2.5-02P, DS2.5-10P. Marking label TM20W.
