256-501 WAGO Terminal Blocks

WAGO 256-501 is a printed circuit connector with a short circuit breaking rating as per IEC/EN 60664-1. It features nominal and rated voltages of 320V for overvoltage category III/3 and pollution degree 3, and 630V for category II/2, with a rated impulse voltage of 4kV across these categories. The rated current is 24A according to IEC/EN standards. Under UL 1059, it has a rated voltage of 300V and rated currents of 15A for Use Group B and 10A for Use Group D. CSA approvals mirror the UL ratings with identical voltage and current specifications for both Use Groups B and D. This connector has a single connection point, supports 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 both insulated and uninsulated ferrules. The strip length for wire preparation is specified as 5 to 6mm (0.2 to 0.24 inches), and the conductor connection direction to the PCB is at a 45-degree angle. Physically, it has a pin spacing of 7.5/7.62mm (0.295/0.3 inches), dimensions of 10.3mm in width, 22.2mm in height, and 17.6mm in depth, with a solder pin length of 4mm. The connector is made from Polyamide (PA66) in gray, featuring a flammability class of V0 per UL94, 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 1.2g, and is RoHS compliant without exemptions. The product is packaged in boxes of 400 pieces, has a GTIN of 4044918810777, and is manufactured in Switzerland with a customs tariff number of 85369010000.
