Description
The Enwitec Master Unit for 12 Battery Storage Systems Parallel Connection is a 48V battery protection series with magnetic-hydraulic protection switches has been developed to protect stationary and mobile battery storage systems of various technologies (lead, lithium ion) and their cabling against overcurrent and short circuit. Depending on the design, the voltage limits for DC operation are between 60VDC…75VDC due to the system voltage. The maximum short-circuit current shall not exceed 10kA. The circuit breakers were also tested for higher loads and survived harmless short-circuit currents of more than 25kA, but the approval according VDE/UL and the applicable standard IEC/EN 60947-2 allows only 10kA within its special test conditions.
The lithium energy storage systems within the scope of this directive already have protective devices for the short-circuit protection, therefore a high short-circuit current in the cabling won’t occur.
