The Mersen V076263 (catalogue number DN00UC10C315L) is a Protistor® NH Size 00 high-speed semiconductor fuse engineered to provide exceptional protection for modern power electronic equipment. Designed with an ultra-fast aR operating characteristic, it delivers rapid short-circuit protection for sensitive semiconductor devices including IGBTs, thyristors, diodes and rectifier assemblies.
Rated at 315 A and 1000 V AC (IEC), the V076263 provides dependable protection for industrial drives, power converters, UPS systems and renewable energy installations. Its square-body NH Size 00 construction with DIN 80 blade contacts and integrated striker enables straightforward installation into compatible fuse bases and switchgear.
Manufactured using silver-plated contacts and low I²t technology, the Protistor® fuse minimises thermal and mechanical stress during fault conditions, helping to maximise equipment uptime while protecting valuable semiconductor components.
Protistor® high-speed semiconductor fuses are engineered specifically for modern power conversion systems where semiconductor devices require extremely rapid protection from short-circuit currents. Their low I²t performance significantly limits thermal energy during faults, reducing the risk of costly damage to critical power electronics.
The Mersen V076263 is widely used by OEM manufacturers and industrial engineers in applications requiring dependable semiconductor protection combined with high interrupting performance and reliable operation.
