737-703 WAGO Industrial Automation Components

WAGO 737-703 is an automation part with a short circuit breaking rating and electrical data adhering to IEC/EN standards, including a nominal voltage (III/3) of 630V, rated impulse voltage (III/3) of 8kV, rated voltage (III/2) of 1000V, rated impulse voltage (III/2) of 8kV, nominal voltage (II/2) of 1000V, rated surge voltage (II/2) of 8kV, and a rated current of 21A. It features ratings between modules and decks, with specific ratings for different overvoltage categories and pollution degrees. UL and CSA approvals are included, with rated voltages of 300V and rated currents of 10A for both UL and CSA in Use Groups B and D. The part has 9 connection points, supports a single connection type, and has three levels. It utilizes CAGE CLAMP connection technology, operable with an operating tool, and accommodates solid and fine-stranded conductors ranging from 0.08 to 2.5mm2 (28 to 12 AWG), including options for insulated and uninsulated ferrules. The strip length for connections is 5 to 6mm (0.2 to 0.24 inches), and the conductor connection direction to PCB is at 45 degrees. Physical specifications include a pin spacing of 10mm (0.394 inches), width of 26mm (1.024 inches), height of 44mm (1.732 inches), depth of 31mm (1.22 inches), and a solder pin length of 4mm. The part is gray, made from Polyamide (PA66) with a flammability class of V0, and uses Chrome-Nickel spring steel (CrNi) for the clamping spring and Electrolytic Copper (ECu) with tin plating for contacts. It operates within a temperature range of -60 to +105°C, is RoHS compliant without exemptions, and comes in a box of 40 pieces. The country of origin is Poland, with a GTIN of 4045454022495 and a customs tariff number of 85369010000.
