Reliable Protection for Electrical Distribution Circuits
A gG fuse link provides full-range protection by responding to both overload currents and severe short-circuit faults. This allows the Mersen FR8GG40V20 to protect cables, conductors and connected electrical equipment throughout its operating range.
During a fault, the fuse limits and interrupts the current before excessive heat or mechanical force can damage the installation. Its compact cylindrical design makes it particularly suitable for electrical panels and equipment where installation space is limited.
Typical Applications
- Industrial electrical distribution panels.
- Commercial distribution boards.
- Low-voltage switchgear and control panels.
- Cable and conductor protection.
- Machinery and equipment supply circuits.
- Compatible cylindrical fuse holders and disconnectors.
