A battery energy storage system (BESS) has to switch massive battery racks onto a live DC bus without a surge that damages contacts or triggers a fault, then keep watching every busbar connection for the heat that signals trouble. Vishay's PTCEL series PTC thermistors handle that inrush current limiting directly, absorbing up to 240 J and surviving 100 000 switching cycles, while NTCALUG ring-terminal NTC thermistors bolt straight to busbars and heatsinks to monitor temperature in the system's hardest working spots.
Behind every safe connection is The DNA of tech.®
