Schaltbau improves reliability and availability of DBT charging stations

DC is the fastest growing and most challenging technology. Schaltbau is one of the few direct-current experts worldwide with decades of expertise. That is why more and more customers are relying on the DC components from Schaltbau.

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 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
