250-1421 WAGO Terminal Blocks

WAGO 250-1421 is an automation part with a short circuit breaking rating as per IEC/EN 60664-1. It features nominal and rated voltages of 160V for overvoltage category III/3 and pollution degree 3, and 320V for category II/2 with a pollution degree of 2, both with a rated impulse voltage of 2.5kV. 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 rated voltage of 300V and a rated current of 5A for Use Groups B and D. This part has 21 connection points and potentials, with a single connection type and level. The connection technology is Push-in CAGE CLAMP with push-button actuation, accommodating solid and fine-stranded conductors ranging from 0.14 to 0.5mm2 (24 to 20 AWG) and a conductor diameter of 0.4 to 0.8mm. The strip length for connections is 8.5 to 9.5mm, with a conductor connection direction to PCB at 45 degrees and a pole number of 21. Physical specifications include a pin spacing of 2.54mm, width of 54.84mm, height of 16.7mm, depth of 12mm, and solder pin length of 3.6mm. The material is gray Polyamide (PA66) with a flammability class of V0, and the clamping spring is made of a copper alloy with tin contact plating. It operates within a temperature range of -60 to +105°C, weighs 7.5g, and is RoHS compliant without exemptions. The product is packaged in boxes with 80 pieces per unit (20 pieces per subunit) and has a GTIN of 4017332749923.
