DC Contactors for Battery Energy Storage Systems
Success Story: Ensuring High Availability and Safety for BESS
Customer profile
- Application: Energy Storage
- Industry: Renewable Energy
- Country: Germany
Customer case
- Our customer, a leading innovator in energy storage solutions, specializes in advanced storage systems for mobile and stationary applications with exceptionally high charging capacities and short charging times, necessitating robust safety measures.
- To ensure safe and continuous operation the customer was looking for contactors that ensure the highest safety standards while integrating easily into their compact systems, all without increasing costs. The industrial contactors needed to be compact and feature an auxiliary contact with a mirrored function to ensure compliance with* ISO13849* safety standards.
- After extensive exchange and consultation with the customer, our team supplied the C300 and C310A/150 contactors, fully meeting all specified requirements.
Our solution
Eddicy DC contactors C300 and C310 ensure safe operation by:
- Being fully bi-directional — safe disconnection of high powers irrespective of the current direction
- Having high short-time withstand current rating Icw of up to 6,000 amps without contact welding
- Having high making capacity Icm up to 6,000 amps leading to increased system availability
- Excellent breaking capacity – the contactor retains its full function when disconnecting high currents.
- Having low energy consumption and low heating thanks to sophisticated coil saving circuit and low contact resistance
- Providing higher safety due to auxiliary contacts – mirror contact functionality IEC60947-4-1, Annex F
