Contactors for DC charging stations for electric vehicles
DBT relies on Schaltbau contactors to reduce high maintenance costs and recurring downtimes

Customer profile
- Application: Unidirectional charging stations
- Industry: EV Charging
- Country: France
Customer case
- DBT is a manufacturer of innovating AC and DC EV charging solutions based in France.
- Because the contactors used in the DC charging stations couldn’t handle high current making cycles, DBT was experiencing recurring field failures and increased costs due to non-planned after-sales interventions.
- A robust contactor with a better contacts reliability was required.

Schaltbau DC contactors C300 have improved safety and reliability by:
- having high thermal continuous current Ith – the contactor can carry up to 500 A continuously
- having high short time making capacity Icm with possible making cycle up to 6,000 A
- having auxiliary switches with mirror contact function, which replicate the status of the main contacts accurately
Further customer benefits:
- Local customer assistance through experienced Schaltbau engineers
- Schaltbau France delivered a complete drop-in solution (distribution plate) that enabled the customer to replace the previous contactors without having to change the design of the charging stations
