    Features

    Sealed with high-strength epoxy resin, no risk of arc leakage, ensuring no fire or explosion within the service life.
    Potting with mainly nitrogen inert gas improves arc extinguishing performance and effectively prevents contact oxidation and burnout. The contact resistance is low and stable, and the contact part can meet the IP67 protection grade.
    300A 85ºC long time current carrying capacity.
    The insulation resistance reaches 100MΩ (1,000VDC), and the withstand voltage between the contact and the coil is 3.5kV.
    Compliant with IEC 60664-1, GB/T14048.1 and GB/T14048.4 requirements.
    Compliant with RoHS (2015/863/EU), REACH (1907/2006/EC) requirements.
    Safety certificate: CE, CCC.
