MERSEN FUSE 400V FB 16 A 6.32 MI6FB40V16

Why Choose the Mersen K084373 MI6FB40V16 Semiconductor Fuse?

The Mersen K084373, catalogue reference MI6FB40V16, is a compact high-speed semiconductor protection fuse designed to safeguard sensitive electronic components and power semiconductor devices against overcurrent and short-circuit faults. Its very fast-acting FB characteristic helps restrict the damaging energy passed through connected equipment during an electrical fault.

Part of the Mersen 6.3 × 32 mm FA/FB 400 V miniature fuse series, the K084373 combines rapid fault interruption with a space-saving cylindrical cartridge format. Its performance makes it suitable for power electronic assemblies, industrial control equipment and automation systems where conventional general-purpose fuses may not operate quickly enough to protect sensitive components.

With a rated current of 16 A and a rated voltage of 400 V AC, the Mersen K084373 is designed for clip mounting within a compatible fuse holder. This version is supplied without a striker, making it suitable for installations where local or remote mechanical fuse indication is not required.

Fast Protection for Sensitive Power Electronics

Power semiconductor devices can be damaged by rapidly rising fault currents before conventional circuit protection devices have time to respond. The Mersen K084373 uses a high-speed FB fuse element to interrupt excessive current quickly, helping reduce thermal stress and limit the energy transferred to sensitive components.

Its compact 6.3 × 32 mm format allows integration into space-restricted electronic equipment, power conversion assemblies and industrial control panels. When installed within a correctly rated fuse holder, it provides a replaceable and dependable protection solution for demanding power electronic applications.

Typical Applications

• Semiconductor device protection.
• Power converters and rectifier equipment.
• Variable speed drives.
• Industrial power supplies.
• Automation and electronic control equipment.
• Power electronic and OEM assemblies.
