The WUK series high current wiring terminals ensure reliable connection of large cross-section wires in structural design: the ribbed plug-in crimping frame ensures the three point alignment of wire connection; The bottom surface of the crimping frame is designed with threads to ensure low transition resistance on the contact surface after wiring; The terminal insulation component is composed of two parts that are connected to the shell to form a closed insulation whole. By using the spring clip provided, it can be conveniently and quickly installed on the standard guide rail of TH35-7.5 or G32-18. Flame retardant to ULVO level. The wire pressing frame is made of quenched and hardened steel, which has been galvanized and passivated. It can withstand the torque of steel screws with huge torque. The surface of the copper conductor is coated with tin lead alloy, ensuring that the conductor and cable remain airtight, low resistance, and permanently connected. This wiring system is widely used by everyone;
