HC-STAK 25 HV Interconnection System

High Voltage E-motor Connector Systems

The HC-STAK 25 HV interconnection system is specifically designed to provide a safe and reliable connection between the HV battery and inverter or the power distribution and e-motor. With a voltage rating of up to 1,000 VDC and a current carrying capability of up to 257 A at 85°C (50 mm² wire) the HC-STAK 25 product is a high-performance interconnection system that is both scalable and capable of reliable high-power distribution to each aggregate. A noteworthy double ended-fork terminal system provides a low contact resistance arrangement while meeting sealing, shielding, and touch-safe requirements in a very compact package. It has the flexibility to interconnect with a wide range of conductor cross-sections, geometry, and materials.
