The Mersen E300614, catalogue number PC30UD69V160DSI, is a premium square body high-speed semiconductor fuse engineered to provide ultra-fast protection for modern power electronic equipment. As part of the trusted Mersen Protistor® Size 30 series, this fuse is specifically designed to protect IGBTs, thyristors, diodes and other semiconductor devices against damaging short circuits and fault currents. Featuring robust DIN 110 blade terminals with an integrated striker indicator, it delivers dependable protection for demanding industrial applications.
Manufactured using precision die-cut fuse elements embedded in solidified silica sand, together with silver-plated contact surfaces and non-magnetic hardware, the E300614 offers exceptionally low let-through energy (I²t). This helps minimise damage to expensive semiconductor devices while improving equipment reliability and reducing costly downtime.
With a 160 A current rating, 690 V AC IEC rating and 700 V AC UL rating, the Mersen E300614 is ideally suited for variable frequency drives, UPS systems, industrial converters, rectifiers, renewable energy installations and other industrial power electronic equipment requiring dependable semiconductor protection.
High-speed semiconductor fuses are designed to interrupt fault currents before sensitive semiconductor devices can be damaged. The Mersen Protistor® Size 30 range delivers extremely fast fault interruption with low I²t values, making it ideal for protecting modern power conversion equipment while improving system reliability and reducing maintenance costs.
The E300614 is widely used in industrial drives, power converters, UPS systems, rectifiers, renewable energy installations and automation equipment where dependable semiconductor protection is essential.
