Nomination to supply Eddicy C800 contactor and HV connector underscores expertise in advanced electric transport applications
MUNICH, April 8th, 2025 – Schaltbau, a global leader in direct current (DC) technology, has been selected to supply its bidirectional high-voltage C800 contactor as well as its HV connector for an electric truck series by a leading European OEM, known for light, medium, and heavy commercial vehicles. The development partnership, the production order starting mid-2025 with a duration of several years, as well as on-going discussions about the manufacturer’s upcoming megawatt-charging projects are testament to the successful positioning of Eddicy as a trusted supplier for a wide range of e-mobility applications.
The C800 series will be used in the truck’s power distribution unit (PDU), ensuring maximal safety, performance and durability – especially in battery emergency cases, in which the contactor safely disconnects the current to safeguard vehicle, driver and freight. The bi-directional Eddicy contactor is notable for its high current carrying capacity and its high energy efficiency, making it perfectly suited to switch power in a small space and in applications with energy recovery, such as the PDU of modern e-vehicles. The C800 has a making capacity of up to 4,500 amps, can permanently carry up to 5,000 amps and, in the event of a short circuit, even 6,000 amps may flow for 20 milliseconds without the contacts welding. Thus, the contactor retains its full function to switch large power when required, regardless of the direction of the current. Schaltbau’s HV connectors will be used in connection between truck and trailer to enable safe power to auxiliary refrigeration systems.
“We are pleased to have been chosen for a truck series which will combine the longer service life and lower maintenance of electric truck drives with a much lighter environmental footprint,” said Helmut Pusch, CEO of Schaltbau GmbH Group. “Global demand for battery-powered commercial vehicles is increasing rapidly. With our high-power contactors, we contribute to bigger ranges, faster loading speeds and operational safety, thus supporting the transition towards more electric road transport across all vehicle classes.”
To achieve comparable power in electric trucks as in conventional combustion truck engines, high DC voltages are indispensable. Schaltbau’s contactors play a crucial role in the truck’s safety circuit: They reliably switch high currents during normal operation and ensure the galvanic isolation of both poles of the high-voltage battery from the vehicle’s high-voltage grid in the event of a short-circuit or thermal overload. Hence, they protect the vehicle, its occupants and transported goods.
