Schaltbau DC contactors ensure safety of energy storage systems
Schaltbau Success Stories
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 contactors from Schaltbau.
Customer profile
- Application: Energy Storage Sytems
- Industry: Renewable Energy
- Location: worldwide
Customer case
- A leading manufacturer of long-term energy storage systems was looking for an alternative to gas encapsulated contactors.
- The solution used so far led to recurring field failures resulting in system downtime.
- A more robust contactor was required to improve system availability and total cost of ownership for the customer.
Schaltbau DC contactors ensure safe operation by:
- being fully bi-directional: Safe disconnection of high powers irrespective of the current direction
- having high making capacity Icm up to 4,000 amps: Which leads to increased system availability
- excellent breaking capacity: The contactors retain its full function when disconnecting high currents
- having low energy consumption and low heating thanks to sophisticated coil saving circuit
- providing higher safety due to auxiliary contacts: Mirror contact functionality IEC 60947-4-1, Annex F
Moreover, the customer’s total cost of ownership has improved.
