High voltage DC contactors
September 2018, Electrical Power & Protection
Gigavac’s HX Series Epic (extended performance impervious ceramic) hermetically-sealed, high-voltage DC contactors are among the smallest UL508, approved contactors for 1000 V hot switching. Since first introducing the Epic seal in 2006, Gigavac sealed contactors have become the preferred choice for many applications requiring sealed switching. Utilising the seal means these contactors exceed the sealing requirements of IP67 and IP69. Going beyond hermetic sealing, the HX series can withstand the rigors of virtually any harsh environment, whether underwater or in the desert sun. They are particularly suited for inverter systems, battery packs and combiner boxes in solar or wind power systems. Additionally, the HX series is ideal for EVs with high-voltage battery systems, such as high-performance electric vehicles, electric buses and electric trucks. The series now includes packaging options with the HX21, HX22 and HX200. Other features include:
• Contactors feature internal transorb for coil suppression.
• Current ranges: 200, 300, 350, 400 and 1000 A.
• Coil voltages: 12, 24 or 48 V.
• Hot switching up to 1000 VDC.
