770-621 WAGO Electrical Connector Accessories

WAGO 770-621 is an automation part with a short circuit breaking rating and electrical data adhering to IEC/EN 60664-1 standards, including a nominal voltage of 400V, rated impulse voltage of 6kV, and a rated current of 25A. It is designed for overvoltage category III and pollution degree 3 environments. 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 600V and 23A. The part features approximately 1mΩ of contact resistance and 0.25mΩ contact transition plug/socket. It has a total of 5 potentials with a preceding PE contact and a 5-pole connection. The physical dimensions include a pin spacing of 10mm, width of 54mm, height of 35.9mm, and depth of 48.9mm. It is suitable for general mains applications, coded as A, and marked for L3 L2 L1 PE N potentials. The mating force of a plug-in connection ranges from approximately 20 to 70N, with a retention force when locked of >80N, and an unmating force of approximately 20 to 70N, depending on the pole number, supporting up to 200 mating cycles without resistive load. It is a T-distribution connector with an IP20 protection type, increasing to IP2xC when mated. The plug-in connection is a socket/plug type with mismating protection and a locking lever for secure locking. The part is black, made from Polyamide (PA66) with a UL94 V0 flammability class, and uses copper or copper alloy contacts with tin plating. It has a fire load of 0.503MJ and weighs 25.4g. It can be processed at temperatures between -5 and +40°C, operates continuously between -35 and +85°C, and is designed for insulating parts up to 105°C. Packaged in boxes of 50 pieces, it is manufactured in Germany with a GTIN of 4044918935005 and a customs tariff number of 85366990990. It complies with RoHS without exemptions.
