Why Choose the Mersen J090513 Quick-Acting Miniature Fuse?
The Mersen J090513 is a compact and dependable 5 × 20 mm quick-acting miniature fuse designed to protect electrical distribution circuits, industrial controls and electronic equipment against excessive current. Part of the established Mersen 5SF IEC miniature fuse series, it responds rapidly to overloads and short circuits to help protect connected components.
Its fast-acting operating characteristic makes the J090513 suitable for circuits where prompt fault interruption is required and substantial normal inrush currents are not expected. The transparent glass cartridge body also supports straightforward visual inspection during installation, servicing and fault diagnosis.
With a rated current of 0.63 A, equivalent to 630 mA, and a rated voltage of 250 V AC, the Mersen J090513 provides reliable protection in a standard miniature cartridge format. It is suitable for compatible fuse clips and holders used throughout industrial, commercial and OEM electrical equipment.
