Why Choose the Mersen K301769 High-Speed Semiconductor Fuse?
The Mersen K301769 is an industrial high-speed semiconductor protection fuse designed to protect sensitive power electronic components against damaging short-circuit currents. Its rapid operating response helps limit fault energy before excessive thermal and electrical stress can damage valuable semiconductor devices.
The K301769 is intended for use within professionally engineered power electronic systems, including equipment containing IGBTs, thyristors, diodes, rectifiers, inverters and converter modules. It is suitable for maintenance, OEM and replacement applications where dependable, high-speed circuit protection is required.
The precise current rating, voltage rating, utilisation category, breaking capacity, I²t values, terminal arrangement and physical dimensions of the K301769 should be verified from the product label or official Mersen technical documentation before purchase or installation.

Reliable Protection for Industrial Power Electronics
Semiconductor fuses are engineered to operate faster than conventional general-purpose fuses. By interrupting excessive current rapidly, they reduce the amount of thermal energy passed into sensitive semiconductor components and help prevent extensive damage to connected equipment.
Correct fuse selection must consider the circuit voltage, continuous operating current, prospective short-circuit current, duty cycle and the protection requirements of the semiconductor manufacturer. A replacement fuse should only be installed when its electrical characteristics, terminal arrangement and physical dimensions are compatible with the original component.
Typical Applications
