770-855 WAGO Industrial Automation Components

WAGO 770-855 is an automation part with a nominal voltage of 400V (III/3) and a rated impulse voltage of 6kV (III/3) according to IEC/EN 60664-1 standards. It supports a rated current of 25A for a 3-pole load and 20A for 4- and 5-pole loads. For the US market, certain versions can 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 about 0.25mΩ contact transition plug/socket. It has 5 total potentials, 1 level, and a 5-pole connection. Physical dimensions include a pin spacing of 10mm, width of 47mm, height of 29.5mm, depth of 14.6mm, and solder pin length of 3.5mm. Designed for control technology, it offers variable coding, B coding, and is marked with potential markings 5 4 3 2 1. The mating force ranges from approximately 20 to 70N, with a retention force greater than 80N and a similar unmating force. It supports up to 200 mating cycles without resistive load and features a straight design with male connector/plug type for PCB connections, including mismating protection and a locking lever for secure connection. The part is made from gray Polyamide (PA66) with a V0 flammability class, chrome-nickel spring steel for the clamping spring, and copper or copper alloy for contacts with tin plating. It weighs 10.8g and can operate between -35 and +85°C, with insulating parts rated for ≤ 105°C. Packaged in boxes of 50, it is RoHS compliant without exemption, has a GTIN of 4017332802611, and is manufactured in Poland.
