GSG RGS4 80A aR fuse for line protection
This cylindrical ceramic-tube fuse carries an 80 A rating with a fast-blow aR characteristic. It is designed for industrial line protection in generator and electrical-supply applications where rapid fault interruption is required. The bolted-joint construction ensures a secure connection in demanding environments.
Bolted-joint installation requires correct torque
The fuse installs by tightening bolts through its end caps, so a calibrated torque tool and clean contact surfaces are essential. Under-torqued joints can overheat, while over-torquing may crack the ceramic body. Verify that the mounting hardware matches the fuse terminals before fitting.
Confirm voltage and interrupting rating match your
The device is rated for 690 V AC with a 50 kA breaking capacity, so the circuit must not exceed either value. Check that the prospective short-circuit current at the installation point stays within the 50 kA limit. Ensure the holder or busbar arrangement accepts the cylindrical form factor.

Questions about this item
How can I confirm the fuse is operating correctly after installation?
Verify that the circuit draws no more than 80 A and that the voltage across the fuse remains within the 690 V rating during normal operation.
What components are included and what must be sourced separately?
The package contains the cylindrical ceramic-tube fuse with bolted joints; mounting hardware and any required fuse holders are not included.
Which rating should I select for a 690 V system needing fast-blow protection at 80 A?
Choose the GSG RGS4 model rated 80 A, 690 V with a 50 kA breaking capacity for fast-blow line protection.
