770-944 WAGO Electrical Connector Accessories

WAGO 770-944 is an automation part with a short circuit breaking rating as per IEC/EN 60664-1, featuring a nominal voltage of 400V (III/3), a rated impulse voltage of 6kV (III/3), and a rated current of 25A. It adheres to overvoltage category III and pollution degree 3. For the US market, certain versions may be used for current interruption in applications with currents below 16A and voltages up to 600V, as per UL 1977, which rates it for a voltage of 600V and a current of 23A. The part has approximately 1mΩ of contact resistance and about 0.25mΩ contact transition plug/socket. It offers four total potentials with a preceding PE contact and a 4-pole connection. The physical dimensions include a pin spacing of 10mm, a width of 40mm, a height of 36.7mm, and a depth of 51mm. Designed for general mains applications, it features coding A, marking N PE 2/L 1/L', and potential marking N PE 2/L 1/L'. The mating force of a plug-in connection is approximately 20...70N, with a retention force when locked of >80N, and an unmating force of approximately 20...70N. It supports 200 mating cycles without resistive load and is classified as an h-distribution connector with outputs at one end. The protection type is IP20 when mated IP2xC, indicating it is not designed for use in open, easily accessible areas. The plug-in connection is a socket/plug type with mismating protection, a locking lever, and a locking system equipped with locking levers to ensure secure connections. The part is black, made from Polyamide (PA66) with a flammability class of V0, and uses copper or copper alloy for contacts with a tin surface treatment. It has a fire load of 2.95MJ and weighs 31.6g. The operating temperatures range from -5 to +40°C for processing and -35 to +85°C for continuous operation, with insulating parts rated for ≤ 105°C. 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, originating from Germany, and has a GTIN of 4045454982034 with a customs tariff number of 85366990990. It is RoHS compliant without exemption.
