Description

  • Design For Dc Applications
  • Excellent Dc Performance
  • Low arc voltage and low energy let-through (I²t)
  • Superior cycling capability
  • Low Watt Losses

Standards / Approvals:

  • Refer To UL248.13 or IEC60269.4
  • Approvals: UL (File: E533379), CE
  • RoHS Compliant

Features & Benefits:

  • Higher voltage rating provides overall system efficiency using smaller, more economical conductors while meeting the needs of higher voltage.
  • Up to ten times faster opening under high fault current conditions helps assure reliable protection of circuits and components.
  • Can be applied in parallel to realize greater ampacity within sizing guidelines.
  • Excellent power of resisting voltaic impingement and environmental temperature tolerance.
  • Excellent resistance to mechanical vibration and impact resistance.
