High power contactor for reliable switching
August 2016
Electrical Power & Protection
Gigavac has announced the latest addition to its line of patented switching devices, the HX460. This new hermetically sealed HVDC contactor redefines the term high power switching by bringing massive power switching capabilities in a compact package. Designed and manufactured in the USA, the HX460 joins Gigavac’s line-up of other sealed switching products including high voltage relays and sealed contactors.
With a package size of approximately 154 x154 mm, the HX460 power connection busbars allow continuous application circuit currents of 600 A and beyond, at 1500 VDC. The SPDT auxiliary contacts are mechanically linked to provide a reliable indication of the main contacts in the closed position. The sealed internal chambers, for both the contacts and coil, assure clean switching in any environment making the HX460 suitable for operation in hazardous classified locations. Safe make and break power switching can be achieved for high power applications up to 600 kW. With bi-directional switching capability and continuous current carry to 600 A, this Gigavac sealed contactor is the perfect choice for many solar applications including inverters, and DC combiner boxes along with a variety of industrial drive systems including rail and traction applications that require a high voltage dielectric rating.
