Han HC modular housing
Han HC Modular inserts
Han HC Modular - For higher currents
The HARTING high-voltage connector series Han® HC offers solutions for power transmission in the range from 70 A to 650 A. The contact inserts are preferably placed in Han® HPR hoods and housings, so that robustness, protection against pressured water, vibration resistance and EMC are guaranteed. The wide range of products is top choice in the transportation market and is used for connecting and supply traction or auxiliary inverters, drive motors and sub-systems such as brakes or air-conditioning units. The high-voltage connectors are also often used in a wide range of different applications in the fields of wind energy, power generation, transmission and distribution (PGTD).
Features:
- Available with crimp, axial screw or screw termination technology
- High current carrying capacity
- Safe and robust version for a wide range of different environment conditions
- Compactness: High power density despite relatively small dimensions
- High number of contacts possible
- Safe power transmission via high contact masses

Step 1:
The diameter of the outer insulation of the cable must not exceed 19.5 mm. Strip the cable to 19 mm. Route the cable through the hood.
Step 2:
Press the Han® HC-contact onto the end of the cable and use a torque wrench to apply a torque according to Table 1. All cable strands must be inserted completely into the contact chamber. During assembly, hold the contact at the same time with the contact to prevent axial movements and torsion.
Step 3:
Guide perforated plate over the insulated body.
Step 4:
Fit frames into the hexagon structure of the HC-contact and pay attention to the coding. Then screw the frames to the perforated plate.
Step 5:
Insert the contact package into the hood.
Step 6:
The four attachments M3 (tightening torque: 0.5 Nm) must be tightened and the pressure screw of the cable gland fixed according to manufacturer’s specifications.

Step 1:
Strip the conductor to 23+2 mm.
Step 2:
Push the conductor through the cable gland and insert the stripped end into the connection opening of the contact module until the insulation is flush at the contact.
Step 3:
Use a size 8 Allen key, which is inserted into the hole provided on the insertion side of the contact and is pushed into the hexagon socket of the clamping screw, to turn the clamping screw tight in a clockwise direction. During this, hold the conductor in axial position. The clamping screw must be tightened using the specified tightening torque, which depends on the conductor cross-section.
Step 4:
When all the modules are clamped, they are assembled in the housing using 2 frames Tightening torque of the fastening screws = 0.5 Nm). For this, the modules have 2 parallel ribs (connected by a cross-bridge) on the outside. The 1-pin frame is inserted between these ribs. The cross-bridge must fit into the frame recess. The 2-pin frames are drawn over the ribs (see sketch). Here, the heads of the M3 fastening screws of the frames must be facing the insertion side of the modules. Each module can be mounted turned through 90°. This can be used to generate different codings. Care must be taken that the modules of the corresponding mating connector are aligned in the same position, otherwise insertion is not possible.
Step 5:
After assembly of the modules in the housing, the tightening torque of the clamping screws can also be checked and corrected (tightening of the clamping screw).
Step 6:
Generally speaking, care must be taken during assembly of the cable gland that no lateral forces act on the contact system during cable laying and after attachment of a tension relief.
