HV – High power connectors for DC applications

Connectors up to 1,000 V DC and 470 A for power transmission

HV series
One-handed operation – thanks to the sliding mechanism on the handle of the socket housing.

Plug with cable guide in corrugated pipe

Schaltbau’s HV series connectors feature solid power and signal contacts and are suitable for a wide range of high-current applications. The robust connectors have a modular design and protection against accidental contact. They are IP69K certified and designed for a high number of mating cycles. The HV connectors are perfect for high power rating. Places of application can be the energy transmission between rail cars or equally the connection of track and trailer on heavy e-vehicles. Other applications include the connection of powerful battery packs – here the HV series is used as a high-performance charging connector.


Wide power range

Rated voltages up to 1,000 volts and rated currents up to 470 amps. Main contacts in the plug and socket housing safely protected against accidental contact.

Rugged housing

One-handed operation – thanks to the sliding mechanism on the handle of the socket housing. This saves effort and ensures safe locking and unlocking of the plug in the socket.

Feedback plug inserted

Optional switching element in the socket housing signals a correctly plugged-in connector.


Solid power contacts for different connection cross-sections up to 95 mm2 and 4 universally applicable signal contacts are available. Also configured with cable or individual conductors in a robust corrugated pipe.


Meets the requirements of UL94-V0 and the
following fireprotection standards EN 45545.
