HX22 Small, compact Contactor for switching +1000 V dc.

HX22 is the first in Gigavac´s new HX series of high voltage contactors. The HX22 is the smallest UL508 recognized contactor for high current switching at 1000Vdc. The HX22 exceeds IP67 and IP69 sealing requirements in addition to being RoHS compliant. UL rated for switching 175 Amps at 1000 V dc and a continuous duty up to 300 Amps the HX22 was developed for use in solar combiner boxes and inverters. Lightweight and compact (about 3.6 x 3.2 inches) the HX22 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 –55ºC to 85ºC. The HX22 is not position sensitive which allows for easy mechanical arrangement in any circuit. High Efficiency Dual DC Coils – Very low 12, 24, or 48Vdc continuous power coils with no EMI emissions or cross-talk on your system control power – Ideal for battery powered systems or where low coil power consumption is needed.
