The 78.004.0353.0 is a modular female contact insert designed for the revos FLEX series of industrial multipole connectors. This 3-pole insert features turned contacts with a diameter of 3.6 mm and is constructed from halogen-free polycarbonate (PC) in pebble gray (RAL 7032) with UL 94 V-0 flammability rating. The insert is rated for a maximum current of 35 A per contact and operates at 630 V AC (690 V mains voltage) with an overvoltage category of 8 kV/3, providing robust electrical performance for demanding industrial applications. The female insert integrates seamlessly into modular connector frames and accepts crimp contacts for flexible wire connection configurations. This component is commonly used in industrial control systems, power distribution panels, and machinery interconnects where reliable, high-current multipole connections are required.
