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 solution

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
