256-504 WAGO Terminal Blocks

WAGO 256-504 is an automation part with a short circuit breaking rating as per IEC/EN 60664-1. It features nominal voltages of 320V (III/3), 320V (III/2), and 630V (II/2), with rated impulse voltages of 4kV for both III/3 and III/2, and a rated surge voltage of 4kV for II/2. The rated current is 24A according to IEC/EN standards, and it falls under the overvoltage category III / Pollution degree 2. UL 1059 approvals indicate rated voltages of 300V and rated currents of 15A for Use Group B, and the same voltage with a 10A current for Use Group D. CSA approvals mirror these UL ratings for both Use Groups B and D. The part includes 4 connection points, with a single connection type across one level, utilizing CAGE CLAMP technology and push-button actuation. It accommodates solid and fine-stranded conductors ranging from 0.08 to 2.5mm2 / 28 to 12 AWG, including specific types with insulated or uninsulated ferrules. The strip length for connections is 5 to 6mm / 0.2 to 0.24", with a conductor connection direction to PCB at 45° and a pole number of 4. Physical specifications include a pin spacing of 7.5/7.62mm / 0.295/0.3", dimensions of 32.9mm width, 22.2mm height, 18.2mm height from the surface, and 17.6mm depth. The solder pin length is 4mm, with dimensions of 0.7 x 0.7mm, and a drilled hole diameter with tolerance of 1.1 (+0.1)mm. It features a THT PCB contact, in-line solder pin arrangement, and two solder pins per potential. The part is gray, made from Polyamide (PA66) with a V0 flammability class per UL94, and uses Chrome-Nickel spring steel (CrNi) for the clamping spring, with electrolytic copper (ECu) contacts plated in tin. It has a fire load of 0.092MJ and weighs 4.8g. It operates within a temperature range of -60 to +105°C, is RoHS compliant without exemptions, and comes in a box of 140 pieces with the country of origin being CH. The GTIN is 4044918808392, and the customs tariff number is 85369010000.
