MERSEN FUSE HA 25 T 2,5 A W090685

Why Choose the Mersen W090685 Semiconductor Miniature Fuse?

The Mersen W090685 is a compact and reliable semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and industrial control equipment against damaging overcurrent conditions. As part of Mersen's HA 25 semiconductor protection fuse range, it provides dependable circuit protection while accommodating the temporary current surges commonly produced when electronic equipment starts.

The W090685 features a super slow or super time-delay (TT) operating characteristic. This controlled response helps prevent unnecessary fuse operation during brief and harmless inrush currents while ensuring sustained overcurrents are interrupted before they can cause excessive electrical or thermal stress to connected components.

With a rated current of 2.5 A, a rated voltage of 220 V AC and a compact 6.3 × 32 mm cylindrical format, the Mersen W090685 is suitable for semiconductor protection, control apparatus and industrial electronic equipment. Its clip-mounted design enables straightforward installation in compatible fuse clips and holders.
