Why Choose the Mersen B330235 High-Speed Semiconductor Fuse?
The Mersen B330235 is an industrial high-speed semiconductor fuse developed to protect sensitive power electronic components against damaging short-circuit currents. Its fast current-limiting characteristics help reduce the peak current and fault energy transferred to connected semiconductor devices.
High-speed fuses operate significantly faster than conventional general-purpose fuse links, making them suitable for protecting components such as diodes, thyristors, IGBTs and rectifier assemblies. The B330235 is intended for use in compatible industrial drives, inverters, converters, power supplies and other electronic power-control equipment.
The complete Mersen B330235 manufacturer reference should be used when sourcing a replacement. Because visually similar semiconductor fuses may have different voltage, current, operating-class, I²t and mechanical characteristics, the product ratings must be confirmed against the original fuse label or current Mersen technical documentation before installation.

Reliable Protection for Industrial Power Electronics
Power semiconductor devices can suffer permanent damage within milliseconds when subjected to excessive current. A correctly selected high-speed fuse interrupts serious faults rapidly and limits both the magnitude and duration of the fault current, helping protect valuable electronic components.
Selection should be based on more than the fuse's physical dimensions or nominal current rating. The circuit voltage, continuous load current, prospective short-circuit current, operating duty and energy-withstand characteristics of the protected semiconductor must all be considered.
Before replacing an existing fuse, confirm that the complete Mersen reference and every relevant electrical and mechanical specification match the requirements of the equipment manufacturer.
