Hi-amperage connector series

BIRNS answered the industry’s call for enhanced current capabilities and launched the 225 Amp BIRNS Meridian se- ries this year — a high performance, high current dry-mate interconnect range suitable for deep submergence applica- tions. The series is available in straight or 90° con? gurations and offers standard and reverse-gender options, all with- standing reverse pressure. BIRNS Meridian connectors are open-face rated to 6,000 meters and select sizes are DNV 12 September/October 2024
