The Mersen R300119 (PC30UD69V80D1A) is a Protistor® Size 30 square body high-speed semiconductor fuse designed to provide ultra-fast protection for modern power conversion equipment. Featuring an aR ultra-fast operating characteristic, it protects sensitive semiconductor devices including IGBTs, MOSFETs, thyristors and diodes against damaging short-circuit currents.
Manufactured using precision die-cut silver fuse elements embedded in solidified sand, the fuse provides excellent current limitation, low let-through energy and a high interrupting rating. Silver-plated contacts, non-magnetic hardware and an integrated striker indicator ensure dependable long-term performance whilst simplifying maintenance and remote status indication.
Rated at 80 A, with 690 V AC (IEC) and 700 V AC (UL) voltage ratings, the R300119 is ideally suited to industrial drives, UPS systems, renewable energy converters, motor drives and other demanding semiconductor protection applications.
The Protistor® Size 30 range has been specifically developed to protect valuable semiconductor devices from damaging fault currents. Its exceptionally fast response and low let-through energy help maximise equipment reliability whilst reducing maintenance costs and production downtime.
These fuses are widely used throughout industrial automation, renewable energy systems, UPS installations, industrial motor drives and power conversion equipment where dependable semiconductor protection is essential.
