The 1745780000 is a size 6, female HDC HE series insert designed for heavy-duty connectors, providing 16 poles with a tension clamp connection. It is rated for 500 V and 16 A according to DIN EN 61984, with a UL/CSA rating of 600 V AC/DC, and can withstand an impulse voltage of 6 kV. The insert is constructed from PC glass-fibre reinforced material with a V-0 flammability rating and features silver-passivated copper alloy contacts, ensuring a low volume resistance of ≤ 2mΩ and a lifespan of at least 500 plugging cycles. The tension clamp technology is designed to be virtually maintenance-free, establishing a safe, permanent, and vibration-proof connection for conductor cross-sections from 0.25 mm² to 2.5 mm², making it ideal for demanding industrial applications.
