MERSEN FUSE 400V SA 0,1 A 6.32 MI6SA40V0,1

Why Choose the Mersen M078901 Medium Time-Lag Semiconductor Fuse?

The Mersen M078901 is a compact medium time-lag semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and control apparatus against sustained overcurrent and short-circuit faults. Part of the Mersen MI6SA 400 V fuse series, it combines dependable fault protection with the ability to withstand normal short-duration current surges.

Its SA medium time-lag operating characteristic makes the fuse particularly suitable for electronic circuits that experience temporary inrush currents during start-up or switching. This helps prevent unnecessary fuse operation while ensuring prolonged overloads and potentially damaging faults are interrupted effectively.

With a rated current of 0.1 A, a rated voltage of 400 V AC and a compact 6.3 × 32 mm cylindrical body, the Mersen M078901 provides precise protection for low-current industrial and electronic circuits. Its clip-mounted format enables straightforward installation and replacement within compatible fuse holders.
