770-688 WAGO Electrical Connector Accessories

WAGO 770-688 is a distribution connector designed for general mains applications with a short circuit breaking rating as per IEC/EN 60664-1. It features a nominal voltage of 250V (III/3), a rated impulse voltage of 4kV (III/3), and a rated current of 25A according to IEC/EN standards. For the US market, under UL 1977, it has a rated voltage of 600V and a rated current of 23A, with specific versions suitable for current interruption in select applications below 16A. The connector has approximately 1mΩ of contact resistance and 0.25mΩ contact transition plug/socket. It supports three potentials, with a three-pole connection and a pin spacing of 10mm. The physical dimensions include a width of 38mm, a height of 52.5mm, and a depth of 46mm. It is coded as "A" with plain marking and has a mating force of approximately 20...70N, a retention force when locked of >80N, and an unmating force of approximately 20...70N, supporting up to 200 mating cycles without resistive load. The protection type is IP20 when mated IP2xC, indicating it is not designed for open, easily accessible areas. The plug-in connection features socket/plug contact type with mismating protection and a locking lever system to ensure secure connections. It is made from white Polyamide (PA66) with a flammability class of UL94 V0, and the contacts are copper or copper alloy with tin plating. The environmental operating temperatures range from -35...+85°C, with insulating parts rated for ≤ 105°C. Packaged in boxes of 10 pieces, it has a GTIN of 4045454251604 and is RoHS compliant without exemptions.
