The Mersen H330241, catalogue number DN00UB69V200L, is a Protistor® square body high-speed semiconductor fuse designed to provide exceptional protection for modern power electronic equipment. Featuring an NH size 00 body with DIN 80 blade contacts, this ultra-fast aR characteristic fuse delivers reliable short-circuit protection for sensitive semiconductor devices including diodes, thyristors and IGBTs.
Rated at 200 A and 690 V AC (IEC), the H330241 has been engineered to minimise let-through energy (I²t), helping to protect expensive semiconductor components while reducing equipment downtime. Silver-plated contacts, a ceramic body and integrated striker indicator ensure dependable performance in demanding industrial environments.
The Protistor® range is widely used in industrial drives, power converters, UPS systems, renewable energy installations and motor control applications where fast fault clearance and high interrupting capacity are essential.
Unlike conventional industrial fuses, Protistor® semiconductor fuses are engineered to interrupt extremely high fault currents before damaging thermal energy reaches sensitive semiconductor devices. Their low I²t performance helps maximise equipment reliability while protecting costly power electronic assemblies.
The H330241 is particularly well suited to modern industrial systems requiring dependable protection of converters, rectifiers, drives and renewable energy equipment operating in demanding electrical environments.
