257-757 WAGO Industrial Automation Components

WAGO 257-757 is an automation part with a short circuit breaking rating as per IEC/EN 60664-1. It has a nominal voltage of 400V (III/3), 630V (III/2), and 1000V (II/2), with a rated impulse voltage of 6kV for all categories. The rated current is 24A, and it is designed for overvoltage category III / Pollution degree 2. Under UL 1059, it has a rated voltage of 300V and rated currents of 15A (Use Group B) and 10A (Use Group D). CSA approvals mirror the UL ratings with identical voltage and current specifications. The part features a single connection point, with a total of one potential and one connection type across one level. The connection technology is CAGE CLAMP with push-button actuation, accommodating solid and fine-stranded conductors ranging from 0.08 to 2.5mm2 / 28 to 12 AWG, including options for both insulated and uninsulated ferrules. The strip length for connection is 5 to 6mm / 0.2 to 0.24", with a conductor connection direction to PCB at 0° and a pole number of 1. Physical specifications include a pin spacing of 7.5/7.62mm / 0.295/0.3", dimensions of 10.3mm width, 24.4mm height, 20.4mm height from the surface, and 14.2mm depth, with solder pin length of 4mm and dimensions of 0.7 x 0.7mm. The drilled hole diameter with tolerance is 1.1 (+0.1)mm. It features a THT PCB contact with in-line solder pin arrangement and two solder pins per potential. The part is light green, made from Polyamide (PA66) with a flammability class of V0, and uses Chrome-Nickel spring steel (CrNi) for the clamping spring and Electrolytic Copper (ECu) with tin plating for contacts. It has a fire load of 0.026MJ and weighs 1.4g. The operational temperature range is -60 to +105°C. It is categorized under Product Group 4 (Printed Circuit Connectors), with eClass 10.0 and 9.0, and ETIM 8.0 and 7.0 classifications as 27-44-04-01 and EC002643, respectively. Packaged in boxes of 400 (100) pcs, it is manufactured in Poland with a GTIN of 4044918413701 and a customs tariff number of 85369010000. It complies with RoHS without exemptions.
