770-1744 WAGO Electrical Connector Accessories

WAGO 770-1744 is an automation part with a short circuit breaking rating and electrical data ratings per IEC/EN 60664-1, including a nominal voltage (III/3) of 400V, rated impulse voltage (III/3) of 6kV, and a rated current of 25A, with a note that the rated current is 25A for a 3-pole load and 20A for 4- and 5-pole loads. It is categorized under overvoltage category III / Pollution degree 3. For the US market, some versions may be used for current interruption in accordance with the UL certificate for currents below 16A and voltages up to 600V, with a rated voltage (UL 1977) of 600V and a rated current UL 1977 of 23A. The part has approximately 1mΩ of contact resistance and approximately 0.25mΩ contact transition plug/socket. It features a total number of 5 potentials, a 5-pole connection, and a pin spacing of 10mm / 0.394". The physical dimensions include a width of 50mm / 1.969", height of 36.7mm / 1.445", and depth of 46mm / 1.811". Designed for control technology applications, it has a B coding, marking of 1 2 3 4 5 for potential marking, and a mating force of a plug-in connection of approximately 20...70N, with a retention force when locked of > 80N and an unmating force of approximately 20...70N. The number of mating cycles is 200 without resistive load, and it is a distribution connector type with 3-way distribution, offering IP20 protection, which upgrades to IP2xC when mated. The plug-in connection is a socket/plug type with mismating protection, a locking lever, and 4 locking levers included. The material data specifies a gray color, Polyamide (PA66) insulation material, a flammability class per UL94 of V0, and contact material of Copper or Copper alloy with tin plating. It has a fire load of 0.868MJ and weighs 44.3g. Environmental requirements include a processing temperature of -5...+40°C and a continuous operating temperature of -35...+85°C, with insulating parts suitable for temperatures ≤ 105°C. Commercially, it belongs to product group 20 (Winsta), with eClass 10.0 and 9.0 classifications of 27-44-06-03, ETIM 8.0 and 7.0 classifications of EC002567, packaged in boxes of 25 pcs, and has a country of origin of DE, with a GTIN of 4050821687689 and a customs tariff number of 85366990990.
