890-243 WAGO Electrical Connector Accessories

WAGO 890-243 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 16A, with a note that the rated current is 13A for a 3-pole load. 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 14A under UL 1977, with specific versions suitable for current interruption in select applications below 5A and up to 600V. The part has approximately 1mΩ of contact resistance and 0.25mΩ contact transition plug/socket. It offers 3 connection points and the same number of total potentials, utilizing Push-in CAGE CLAMP technology for connection, with an actuation type of operating tool or push-in, and supports various conductor types and sizes. The strip length for connection is 9mm, and it has a 3-pole number with a conductor entry direction to mating direction of 0°. Its physical dimensions include a pin spacing of 4.4mm, a width of 15mm, a height of 11.7mm, and a depth of 34.1mm. Designed for control technology applications, it features a B coding, no variable coding, and is marked 1 2 3 for potential marking. The mating force of a plug-in connection ranges from approximately 20 to 70N, with a retention force of over 80N and an unmating force of approximately 20 to 70N, depending on the pole number, and supports up to 200 mating cycles without a resistive load. It offers IP20 protection, IP40 with strain relief housing, and includes a female connector/socket for the plug-in connection, with mismating protection and a locking lever that can be retrofitted. The part is gray, made from Polyamide (PA66) with a flammability class of V0, and uses Chrome-Nickel spring steel for the clamping spring and tin-plated copper or copper alloy for contacts. It has a fire load of 0.102MJ and weighs 3.6g. Suitable for processing temperatures of -5 to +40°C and continuous operating temperatures of -35 to +85°C, it is RoHS compliant without exemption. The product belongs to group 20 (Winsta), with a packaging unit of 50 pieces per box, originating from Poland, and has a GTIN of 4055143499910 and a customs tariff number of 85366990990.
