Why Choose the Mersen Q215087 DIN D gG Fuse Link?
The Mersen Q215087 is a dependable DIN D gG screw fuse link designed to protect low-voltage cables, conductors and electrical equipment against overloads and short circuits. Identified by the catalogue number NDZGG50V20, this fuse combines a 20 A rated current with voltage ratings of 500 V AC and 500 V DC.
As part of Mersen's established D fuse-links gG series, the Q215087 provides full-range overcurrent protection for general electrical distribution applications. Its current-limiting operation helps reduce the thermal and electrodynamic effects of high short-circuit currents, supporting reliable protection of connected equipment and installations.
Manufactured in the compact NDZ DIN fuse size, the Q215087 is suitable for compatible screw-fuse systems used in distribution boards, installation cabinets and low-voltage power systems. Its blue identification colour allows the 20 A rating to be recognised quickly during installation, inspection and replacement.
