Han-Com(R) K 4/2P+E male screw insert

Harting Han K Series Heavy Duty Power Connector Insert, 80A Current, 830V Voltage - 09380062601

This heavy-duty power connector insert is a panel-mount male contact module designed for industrial electrical assemblies. It combines power and signal contacts in a straight orientation to provide secure, high-current and control connections in harsh environments, with screw termination suitable for varied conductor sizes.

Features & Benefits

• Rated 80 A power current for high-load circuits
  830V power voltage rating for elevated-voltage systems
  Four power and two signal contacts for mixed connections
  Silver-plated copper-alloy contacts for low resistance
  Conductor range 1.5–16 mm² for flexible cable selection
  IP65 protection against dust ingress and water jets

**Applications**

• Suitable for automation control panels requiring mixed power and signal lines
  Ideal for machinery power distribution with high current demands
  Used for portable equipment panels exposed to workshop conditions
  Can be used for industrial motor connection requiring a PE contact
  Used with electrical cabinets needing robust panel-mounted inserts

What conductor sizes are supported for signal circuits?

Signal contacts accept conductors from 0.5 mm² to 2.5 mm² with a specified stripping length of 7.5 mm.

How is earthing implemented in the module?

A dedicated PE contact and an M5 PE screw provide a secure protective-earth connection.

What mechanical endurance can be expected from frequent mating?

The insert is specified for at least 500 mating cycles to withstand repeated connections.

Which torque settings should be used for contact screws?

Tightening torques vary by conductor: 1.2 Nm at 1.5 mm², 2 Nm at 2.5 mm², and 3 Nm for 4–16 mm², with the M6 contact screw at 3 Nm.

What materials and flame rating apply to the insert housing?

The insert is MADE from polycarbonate rated to UL94 V-0 and the contacts are a silver-plated copper alloy.

Notes

The 221-1808 to 221-1791 series of crimp contacts utilise contact extraction tool - stock no. 313-6613. All others utilise extraction tool stock no. 114-7728
