High & Medium Voltage Fuses

Mersen High-Voltage Fuses – Comprehensive Circuit Protection

PT Fuses (Potential Transformer)
Protect voltage transformers in switchgear/metering.
Low current ratings (0.5–10A), high interrupting capacity.

Transformer Fuses
Backup protection for power/distribution transformers.
Time-delay characteristics to handle inrush currents.

Capacitor Fuses
Designed for capacitor bank protection.
Fast-acting to prevent rupture during faults.

R-Rated Fuses
Protect motor circuits (NEMA R-class).
Time-delay for startup currents (typically 100-600A).

E-Rated Fuses
General-purpose HV protection (NEMA E-class).
Used in feeders, disconnects (typically 1-600A).
