Why Choose the Mersen J217128 DII gG/Flink Fuse Link?
The Mersen J217128 is a fast-acting DIN D screw fuse link designed to protect equipment and low-voltage electrical circuits against damaging overcurrents. Identified by the catalogue number DIIFK50V20, this fuse link combines a 20 A rated current with a 500 V AC and 500 V DC voltage rating.
Manufactured in the standard DII fuse size, the J217128 is suitable for established DIN screw-fuse systems used in distribution boards, control panels and industrial installations. Its gG/Flink operating characteristic provides fast fault interruption, helping minimise thermal and mechanical stress on connected equipment.
The fuse features a blue identification colour corresponding to its 20 A rating and includes an indication system for easier inspection. Its robust construction, AC/DC compatibility and recognised DIN format make it a dependable replacement fuse for electrical maintenance, panel building and equipment protection applications.

Reliable Protection for Low-Voltage Equipment
DIN D fuse links interrupt excessive current before it can cause serious damage to cables, components or connected equipment. The fast operating characteristic of the Mersen J217128 is particularly useful where rapid fault clearance is required to limit the energy passing through the circuit.
The D screw-fuse system remains widely installed in low-voltage distribution equipment throughout industrial, commercial and infrastructure applications. Its established design allows the fuse link to be inspected and replaced without changing the complete fuse assembly, helping simplify routine maintenance.
Typical Applications
- Low-voltage distribution boards.
- Industrial electrical control panels.
- Commercial electrical installations.
- Machinery and production equipment.
- Electrical equipment protection.
- DIN screw-fuse assemblies.
