Why Choose the Mersen W330138 BS000UB69V315P Semiconductor Fuse?
The Mersen W330138 BS000UB69V315P is a high-speed Protistor® square body semiconductor fuse-link designed to provide exceptional protection for power semiconductor devices in demanding industrial applications. Featuring an ultra-fast aR operating characteristic, it rapidly interrupts short-circuit faults to protect IGBTs, thyristors, diodes and other sensitive power electronic components.
Rated at 315 A with a 690 V AC IEC and 690 V AC UL voltage rating, the W330138 is ideal for variable speed drives, industrial converters, UPS systems and renewable energy equipment. The integrated striker indicator allows convenient local or remote fuse status indication when used with a compatible microswitch.
Manufactured using silver-plated contact surfaces and precision-engineered fuse elements embedded in solidified silica sand, the BS000UB69V315P provides excellent current limitation, low let-through energy and a very high interrupting capacity, helping minimise damage during fault conditions while improving equipment reliability.

Designed for High-Power Semiconductor Protection
The Mersen W330138 has been engineered specifically for the protection of modern semiconductor power devices. Its ultra-fast aR characteristic limits fault energy before it can damage expensive electronic components, helping maximise equipment availability and minimise costly downtime.
As an aR semiconductor fuse, the BS000UB69V315P is intended primarily for short-circuit protection. Separate overload protection should be provided where required by the equipment manufacturer or applicable electrical standards.
Typical Applications
- Variable frequency drives (VFDs).
- Industrial motor drives.
- Power converters.
- Rectifiers.
- Industrial UPS systems.
- Renewable energy converters.
- High-power automation equipment.
- Semiconductor protection circuits.
