HRC FUSE LINKS & BASES

• HRC fuses, also known as high rupturing capacity fuses, contain a precisely engineered fusible link.
• They interrupt high-magnitude short-circuit currents (up to 200,000A) while allowing temporary harmless inrush during startup.
• Key traits include:
  • High interrupting rating for severe faults.
  • Time-delay to permit motor or transformer inrush.
  • Replaceable fuse links for easy renewal.

Applications of HRC Fuses:

• Protecting transformers.
• Safeguarding motors and generators.
• Backing up drive input fuses.
• Securing capacitor banks.
• Semiconductor protection in switchgear and medium-voltage equipment.
