High Voltage Current Limiting Fuses
CLF (25.8kV High Voltage Current Limiting Fuses)
25.8kV High Voltage Current Limiting Fuses is economically effective and carries excellent break performance which is widely used along with other protective equipment to protect high-pressure circuits and high-voltage equipment (e.g. current transformers, condensers, etc.) from overcurrent or short-circuit current. This light weight product has a high-capacity breaking performance of 40㎄ and is optimal for protecting power receiving circuits and equipment.
Product Attributes
CAP : Ensured compatibility by adopting DIN standards, Element: Secured blocking performance through production using company-owned notching machine, Insulating tube: Used ceramic for high thermal shock resistance
