Why Choose the Mersen B330028 High-Speed Semiconductor Fuse?
The Mersen B330028 is an industrial high-speed semiconductor fuse intended to protect sensitive power electronic equipment against damaging short-circuit currents. Its fast current-limiting operation helps reduce the electrical and thermal energy passed to semiconductor devices during a fault.
High-speed fuses are engineered to respond more rapidly than conventional general-purpose fuse links. This specialised performance makes the B330028 suitable for protecting components such as IGBTs, thyristors, diodes and rectifiers used in industrial drives, converters, inverters and controlled power supplies.
The B330028 manufacturer reference should be used when identifying or sourcing a replacement. As visually similar semiconductor fuses can have different current, voltage, operating-class and energy-limiting characteristics, all electrical and mechanical specifications must be verified against the original fuse or official Mersen documentation before installation.

Reliable Protection for Industrial Power Electronics
Power semiconductor devices may suffer irreversible damage within milliseconds when exposed to excessive current. A correctly selected high-speed fuse limits both the peak fault current and its duration, helping protect connected electronic components and reducing the risk of extensive equipment damage.
Selection of the Mersen B330028 should be based on the complete manufacturer reference together with the circuit voltage, continuous operating current, prospective short-circuit current and energy-withstand characteristics of the protected equipment. Installation should only be completed after the circuit has been safely isolated.
Typical Applications
- Variable frequency drives and motor-control systems.
- Industrial inverters and power converters.
- Rectifier and thyristor assemblies.
- Uninterruptible power supply systems.
- Semiconductor protection circuits.
- Industrial automation and electrical control panels.
