257-747 WAGO Terminal Blocks

WAGO 257-747 is an automation part with a short circuit breaking rating as per IEC/EN 60664-1. It features nominal voltages of 250V (III/3), 320V (III/2), and 630V (II/2), with rated impulse voltages of 4kV for all categories and a rated surge voltage of 4kV for category II/2. The rated current is 24A according to IEC/EN standards. Under UL 1059 approvals, it has rated voltages of 300V and rated currents of 15A for Use Group B and 10A for Use Group D. Similarly, CSA approvals indicate the same voltage and current ratings for Use Groups B and D. The part includes a single connection point with one potential and utilizes CAGE CLAMP technology with push-button actuation. It accommodates solid and fine-stranded conductors ranging from 0.08 to 2.5mm2 (28 to 12 AWG), including options for insulated and uninsulated ferrules. The strip length for connection is 5 to 6mm, with a conductor connection direction to PCB at 0° and a pole number of 1. Physical specifications include a pin spacing of 5/5.08mm, a width of 7.8mm, a height of 24.4mm, a depth of 14.2mm, and solder pin dimensions of 0.7 x 0.7mm. The part is light green, made from Polyamide (PA66) with a flammability class of V0, and uses Chrome-Nickel spring steel for the clamping spring and Electrolytic Copper with tin plating for contacts. It operates within a temperature range of -60 to +105°C, weighs 1.1g, and is RoHS compliant without exemptions. Packaged in boxes of 500 pieces, it is manufactured in Poland with a GTIN of 4044918413510 and a customs tariff number of 85369010000.
