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.
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.

The Mersen B330235 is a high-speed fuse intended to protect compatible semiconductor devices and industrial power electronic equipment against damaging short-circuit currents.
Yes. B330235 is the Mersen manufacturer reference used to identify this particular fuse product.
A general-purpose fuse should not be used as a direct replacement unless compatibility has been confirmed by the equipment manufacturer. Semiconductor fuses have specialised speed and energy-limiting characteristics.
Confirm the complete part number, rated current, rated voltage, operating class, breaking capacity, I²t values, physical dimensions and connection arrangement against the original fuse and equipment documentation.
The fuse should be installed by a suitably qualified electrical professional after the equipment has been isolated and all applicable electrical safety procedures have been followed.
Mersen high-speed fuses are used by equipment manufacturers, panel builders and electrical engineers to protect critical semiconductor components within industrial drives, converters and power-control systems.
