Why Choose the Mersen W330046 BS000GB69V32 Semiconductor Fuse?
The Mersen W330046 BS000GB69V32 is an ultra-fast Protistor® BS88-4 semiconductor fuse-link designed to protect power converters and sensitive semiconductor devices against overload and short-circuit currents. Its gR full-range operating characteristic provides comprehensive protection across the fuse’s specified current range.
Rated at 32 A and 690 V AC, the W330046 is suitable for industrial drives, rectifiers, inverters, uninterruptible power supplies and other power-electronic equipment. Its rapid operation and current-limiting performance help reduce the thermal and electrical energy transmitted to downstream components during a fault.
The fuse uses the recognised British Standard size 000 format with angled bolted terminals for secure installation. It is supplied without a built-in blown-fuse indicator, making it suitable for systems where local or remote indication is provided separately.
Key Advantages
- gR full-range protection for semiconductor circuits.
- Protects against both overload and short-circuit fault currents.
- 32 A current rating for industrial power-electronic equipment.

Full-Range gR Semiconductor Protection
The gR classification identifies a high-speed fuse capable of providing full-range protection for power semiconductor equipment. Unlike an aR partial-range fuse, which is primarily intended to clear short-circuit faults, a correctly selected gR fuse can respond to both sustained overloads and high-level short circuits.
This characteristic can simplify circuit protection and improve equipment safety, although the fuse must still be coordinated with the operating current, semiconductor withstand limits and prospective fault current of the application.
Typical Applications
- Variable frequency and variable speed drives.
- Industrial rectifier systems.
- AC and DC power converters.
- Inverters and uninterruptible power supplies.
- Semiconductor switching circuits.
- Industrial motor-control equipment.
- Power supplies and automation systems.
- Converter circuits requiring selective fuse coordination.
