770-203 WAGO Industrial Automation Components

WAGO 770-203 is an automation part with a short circuit breaking rating as per IEC/EN 60664-1, featuring a nominal voltage of 250V (III/3), a rated impulse voltage of 4kV (III/3), and a rated current of 25A. It is designed for overvoltage category III and pollution degree 3. For the US market, it has a rated voltage of 600V and a rated current of 23A under UL 1977, with specific versions suitable for current interruption in select applications below 16A and up to 600V. The part has approximately 1mΩ of contact resistance and about 0.25mΩ contact transition plug/socket. It includes 6 connection points, 3 total number of potentials, and 3 number of test slots. The connection technology is Push-in CAGE CLAMP with an actuation type of operating tool or push-in, supporting a nominal cross-section of 4mm2 / 12 AWG. It accommodates a wide range of conductor sizes and types, including solid, stranded, and fine-stranded conductors, with specific details for push-in termination and ferrule usage. The strip length for connection is 9mm / 0.35", and it has a 3 pole number with a conductor entry direction to mating direction of 0°. Physically, it has a pin spacing of 10mm / 0.394", a width of 30mm / 1.181", a height of 12.9mm / 0.508", and a depth of 37.5mm / 1.476". It is suitable for general mains applications, features variable coding, and is marked with L PE N for potential marking. The mating force of a plug-in connection ranges from approximately 20 to 70N, with a retention force of locked > 80N, and an unmating force of unlocked approx. 20 to 70N, depending on the pole number. It supports up to 200 mating cycles without resistive load and offers IP20 protection, increasing to IP2xC when mated and secured with a strain relief housing. The part includes a female connector/socket for the plug-in connection, with mismating protection and the possibility to retrofit a locking lever. It is made from Polyamide (PA66) with a flammability class of UL94 V0, and the contact material is a surface-treated copper or copper alloy with tin plating. The part weighs 9.5g, operates within a temperature range of -5 to +40°C for processing and -35 to +85°C for continuous operation, with insulating parts rated for temperatures ≤ 105°C. It is RoHS compliant without exemption, packaged in boxes of 100 pcs, and has a country of origin in DE, with a GTIN of 4044918252225 and a customs tariff number of 85366990990.
