Plug-in type HRC fuse Rate voltage: 3.6kV-40.5kV
The HRC (high rupturing capacity) fuse-links are used to protect transformers, capacitor banks, cable and overhead lines against short-circuits. They protect Switch-gears from thermal and electromagnetic effects of heavy short-circuit currents by limiting the peak current values (cut-off characteristic) and interrupting the currents in several milliseconds.
Features of the Plug-in type HRC Fuse:
Rated voltage 3.6kV~40.5kV, Raed current up to 200A.
High rupturing capacity.
Short-circuit current limiting.
Low rated minimum breaking current (1 min).
Low switching over-voltage (Um).
Can be used with switch disconnector (it is fitted with a medium-size striker pin).
Dimensions according to DIN and IEC Standards.
