High current connectors

High current (HC) connector are interfaces that have been specially developed for the transmission of high currents. They therefore replace previous hardwiring and are used, for example, in transportation technology as well as in power generation and distribution.

The design of the high current connectors depends on the maximum current, the voltage for which they are designed and the environmental requirements. The smallest high current contacts in the HARTING portfolio transmit 70 A and are inserted in a Han-Modular® module.

The most powerful contacts can be placed in housings from the Han® HPR HPTC and HPR Single Pole series, that are relevant for outdoor use. These connectors transmit up to 850 A individually in duet up to 1400 A (HPR HPTC 1400); the upper voltage limit is currently 4.5 kV.
