Schaltbau DC contactors ensure safety of energy storage systems

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.

• Application: Energy Storage Sytems
• Industry: Renewable Energy
• Location: worldwide

• 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.
