## Long description

Eti-Polam WT-1/gF 50A NH1 gF is a replaceable fuse insert designed for low-voltage power distribution and protection of electrical circuits. The insert is shaped for NH1 fuse holders and provides gF (full-range) protection, combining overload and short-circuit interruption capability in a single element. It is intended for use in industrial and commercial switchgear where reliable circuit protection and straightforward replacement are required.
Advantages
The fuse insert delivers full-range gF protection with a clear 50A rating, enabling coordinated protection of downstream circuits and equipment against both overloads and short circuits. Its NH1 form factor ensures compatibility with standard NH1 holders and simplifies maintenance since inserts can be swapped without replacing the entire base. The design supports stable operation under normal load and fast interruption under fault conditions, contributing to safer power distribution systems.
Suitable for
 Low-voltage power distribution in industrial plants
 Commercial switchboards and panels
 Protection of motors, transformers and distribution feeders
 Retrofit or maintenance of NH1 fuse-holder installations

How to use
Install the Eti-Polam WT-1/gF 50A NH1 insert into a compatible NH1 fuse holder according to the switchgear manufacturer’s instructions. Ensure the power is isolated before removing or inserting the fuse insert. Verify correct seating and contact integrity after installation, then restore power and check that the protected circuit operates normally. Replace the insert with the same type and rating when a fuse has operated.
Usage recommendations
Use the fuse insert only within its rated current and in NH1-compatible holders. Select coordination with upstream protection and upstream/downstream devices to ensure selective tripping. Perform periodic visual inspections for signs of overheating or contact corrosion and confirm that the enclosure and protective devices meet applicable safety standards.
