Description

  • Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the need of higher voltage.
  • Up to ten times faster opening under high fault current conditions helps assure reliable protection of circuits and components.
  • Greater ampacity within sizing guidelines, excellent power of resisting voltaic impingement and environment temperature tolerance, excellent resistance to mechanical vibration and impact resistance.

CERTIFICATIONS

  • Refer To UL 248.1/UL 248.13
  • IEC 60269.1/IEC 60269.4 
  • UL, TUV
  • RoHS Compliant
