Gigavac Rounds Out High Voltage Switching Line

New Compact Contactors Ideal for Solar Applications to 1500Vdc

Santa Barbara, California, USA — GIGAVAC announces two additions to their High Voltage Contactor line of Advanced Switching Solutions.  The HX21 and HX200 join the HX22 as the smallest UL508 recognized contactors for high current switching at 1000Vdc.  Designed and manufactured in the USA by GIGAVAC, the HX series features the Patented EPIC® Seal. This provides complete protection beyond what is offered by traditional hermetic seals.

UL rated for switching 175 amps at 1000Vdc and a continuous duty up to 300 amps the HX series was developed for use in solar combiner boxes and inverters.  These are also the perfect contactor choice for any application requiring safe sealed arcfree switching.  Lightweight and compact, only about one pound,  the HX series utilizes GIGAVAC’s EPIC® sealed switching technology which means it can safely be used in nearly any harsh environment including under water and at temperatures from –55°C to 85°C.  HX contactors are not position sensitive. And, now with the addition of the HX21 and HX200 there are multiple mechanical footprint options allowing for easy mechanical arrangement in any circuit.  High efficiency coils are offered in 12, 24, or 48Vdc versions. GIGAVAC’s dual coil design means low coil power consumption and no EMI emission or crosstalk.
