257-657 WAGO Industrial Automation Components

WAGO 257-657 is a printed circuit connector with a short circuit breaking rating as per IEC/EN 60664-1. It features nominal voltages of 630V (III/3) and 1000V (II/2, III/2), with a rated impulse voltage of 8kV for both overvoltage categories III/2 and III/3. The rated current is 24A according to IEC/EN standards. Under UL 1059, it has rated voltages of 300V and rated currents of 15A for Use Group B and 10A for Use Group D, similarly for CSA ratings. The connector has 7 connection points, supports a single connection type with one level, 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 both insulated and uninsulated ferrules. The strip length for connection is specified as 5 to 6mm, with a conductor connection direction to PCB of 0° and a pole number of 7. Physically, it has a pin spacing of 10/10.16mm, dimensions of 72.9mm in width, 24.2mm in height, 14.2mm in depth, and a solder pin length of 4mm. The connector is made from Polyamide (PA66) in gray, with a flammability class of UL94 V0, and uses Chrome-Nickel spring steel for the clamping spring and tin-plated Electrolytic Copper for contacts. It operates within a temperature range of -60 to +105°C, weighs 11.6g, and is RoHS compliant without exemptions. The product is packaged in boxes with 60 pieces per unit for standard packaging units (SPU) and 15 pieces for smaller packaging units, originating from Poland with a GTIN of 4044918677523 and a customs tariff number of 85369010000.
