770-243 WAGO Electrical Connector Accessories

WAGO 770-243 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 environments. For the US market, it is noted that some versions may be used for current interruption in select applications below 16A and up to 600V, according to UL 1977, which rates it for 600V and 23A. The part has approximately 1mΩ of contact resistance and 0.25mΩ contact transition plug/socket. It offers 6 connection points, 3 total number of potentials, and utilizes Push-in CAGE CLAMP technology for connection 1 with various conductor compatibility ranging from 0.5 to 4mm2 / 20 to 12 AWG, including solid, stranded, and fine-stranded conductors, with specific conditions for push-in termination. The strip length for connection 1 is 9mm / 0.35", with a 3 pole number and a conductor entry direction to mating direction of 0°. Physically, it has a pin spacing of 10mm / 0.394", dimensions of 30mm width, 12.9mm height, and 37.5mm depth, and is designed for control technology applications with a B coding, variable coding, and marked 1 2 3 for potential identification. It ensures a mating force of approximately 20...70N, a locked retention force of >80N, and an unmating force of approximately 20...70N, supporting up to 200 mating cycles without resistive load. The protection type is IP20, enhancing to IP2xC when mated and secured with a strain relief housing. It features a female connector/socket type with mismating protection, a retrofitting locking lever, and is made from gray Polyamide (PA66) with a V0 flammability class, Chrome-Nickel spring steel (CrNi) for the clamping spring, and tin-plated copper or copper alloy contacts. It weighs 9.6g, has a fire load of 0.301MJ, and operates within a temperature range of -5...+40°C for processing and -35...+85°C for continuous operation. The product belongs to the Winsta group 20, with a packaging unit of 100 pieces per box, manufactured in Germany (DE), and is RoHS compliant without exemptions.
