Why Choose the Mersen G212020 RECTICUR DV Fuse Link?
The Mersen G212020 is a high-speed 200 A gR semiconductor fuse link designed to protect sensitive power electronic devices against overloads and short-circuit currents. Part of the proven Mersen RECTICUR D range, it provides rapid fault interruption for industrial drives, rectifiers, converters and semiconductor power circuits.
Rated for operation at 500 V AC and 440 V DC, the G212020 is specifically engineered to minimise the let-through energy delivered to semiconductor devices. Its gR operating characteristic provides full-range protection for components including diodes, thyristors, IGBTs and AC/DC motor drives.
Manufactured with a robust ceramic body and nickel-plated or silver-plated copper alloy contacts, the fuse offers excellent resistance to thermal and mechanical stress. A coloured operating indicator provides clear visual confirmation of fuse status, simplifying maintenance and reducing downtime.
