GCS1 8mm Energy Storage Connector Details
The GCS1 12mm connectors are high-current, high-voltage connectors used to interconnect battery modules in a battery energy storage system (BESS). They feature a locking mechanism that allows the connector to be inserted and removed with one hand. The RoHS-compliant battery high voltage connector has a power rated voltage of 1500V DC, with 250A to 350A current ratings, and has an operating temperature range of -40℃ to 125℃.
Guchen GCS1 Series includes a variety of options for 100A to 350A current applications. The GCS1 Series connector also provides finger protection during assembly that meets IP69K requirements, ensuring worker safety while providing reliable performance over many years of operation.

Main parameters:
Applicable wire diameter: 70mm² / 95mm² / 120mm²
Rated current: 250A / 300A / (350A/400A)
Rated voltage: 1500V
