250-403 WAGO Terminal Blocks

WAGO 250-403 is a printed circuit connector with a short circuit breaking rating as per IEC/EN 60664-1. It features nominal and rated voltages of 160V in overvoltage category III/2 and 320V in category II/2, with a rated impulse voltage of 2.5kV for both categories. The rated current is 4A according to IEC/EN standards. Under UL 1059, it has a rated voltage of 300V and a rated current of 5A for both Use Groups B and D. CSA approvals mirror the UL ratings with a 300V rated voltage and 5A rated current for Use Groups B and D. The connector has three connection points, supports a single connection type with one level, and utilizes Push-in CAGE CLAMP technology with push-button actuation. It accommodates solid and fine-stranded conductors ranging from 0.14 to 0.5mm2 (24 to 20 AWG), with a conductor diameter of 0.4 to 0.8mm and a strip length of 8.5 to 9.5mm. The conductor connection direction to the PCB is at a 45-degree angle, and it has a pole number of 3. Physical specifications include a pin spacing of 2.5mm, a width of 9mm, a height of 16.7mm, a depth of 12mm, and solder pin length of 3.6mm. The connector is made from gray Polyamide (PA66) with a flammability class of V0 and features tin-plated copper alloy contacts. It operates within a temperature range of -60 to +105°C and complies with RoHS environmental requirements. The product is packaged in boxes of 520 pieces and has a GTIN of 4044918642828.
