Centralized Combiner Box Solution

Pain Points in the Application Scenario

Maximum short-circuit current of 150kA requires robust isolation and short-time withstand capability at the combining point. DC-side 1.1Ie continuous overload capability ensures stable and safe system operation.

Value of the Solution

Exceptional short-time withstand capability up to 200kA/0.2s prevents downstream equipment damage from high battery short-circuit currents, ensuring electrical-cabin safety. Strong overload current capability ensures stable operation of the battery cabin and prevents PCS overload conditions that could lead to switching-device failures.
