770-845 WAGO Electrical Connector Accessories

WAGO 770-845 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, which adjusts to 20A for 4- and 5-pole loads. It adheres to overvoltage category III and pollution degree 3. For the US market, certain versions may be used for current interruption in select applications below 16A and 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 includes 5 total potentials, 1 level, and a 5-pole connection. Physical specifications include a 10mm pin spacing, dimensions of 47mm in width, 29.5mm in height, 26mm height from the surface, and 14.6mm in depth, with solder pin length of 3.5mm and dimensions of 1 x 0.8mm. The drilled hole diameter with tolerance is 1.5 (-0.1...+0.1)mm. Designed for control technology, it features B coding, variable coding, and is marked 1 2 3 4 5 for potential. The mating force of a plug-in connection ranges approximately from 20 to 70N, with a retention force of >80N and an unmating force of approximately 20 to 70N, depending on pole number, supporting up to 200 mating cycles without resistive load. It has a straight design, female connector/socket type, and is for PCB connection with mismating protection and a 90° mating direction to the PCB. The locking system includes a locking lever. The PCB contact is THT with 2 in-line solder pins per pole. The part is gray, made from Polyamide (PA66) with a V0 flammability class per UL94, and uses Chrome-Nickel spring steel (CrNi) for the clamping spring and tin-plated copper or copper alloy for contacts. It has a fire load of 0.204MJ and weighs 10.3g. 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 classification 27-44-06-05, ETIM 8.0 and 7.0 classification EC002560, packaged in boxes of 50 pcs, originates from PL, has a GTIN of 4017332802581, and a customs tariff number of 85366990990. It is RoHS compliant without exemption.
