High Speed Semiconductor Fuses

Mersen Ferraz Amp-Trap Series fuses are suitable for the protection of higher voltage traction rectifiers. They offer a unique design to minimise peak let-thru current, arc voltages and high-potential faulty currents in extremely short times. They feature GMG / polytube type construction that encases the conductive elements as well as withstand the electrical & thermal stresses caused during the operation. These high-speed fuses further offer bolted / ferrule mount connection to securely attach the fuse to a mounting structure or base.

BUSSMANN high-speed semiconductor fuses (Series FWA) offer a wide range of North American blade and flush-end style fuses & accessories. Their design and construction are enhanced to provide low energy let-through (I2t) at low energy loss. They provide superior cycling capability with excellent DC performance and low arc voltage. Choose from a wide range of these Bussmann semiconductor fuses, available in melamine and ceramic bodies on Raptor Supplies.

Mersen Ferraz Amp-Trap Series A15QS fuses are electrical protection devices suitable to safeguard electrical systems and equipment from overcurrent conditions. They are used in industrial and commercial electrical settings to avoid hazardous electrical faults. They feature visual indication or remote signalling capability, allowing users to easily identify when they require replacement. These A15QS fuses offer optional auxiliary microswitches, providing additional monitoring capabilities and enabling users to integrate them into advanced control systems for enhanced protection and real-time status monitoring. These A15QS fuses maintain a consistent size across all their variants, ensuring ease of installation and replacement.

Bussmann fast-acting FWP Series semiconductor fuses are highly sensitive fuses designed to provide current limitation and cycling performance which combine high-speed tripping with full-range protection. They are made from fibreglass or ceramic in compact sizes, thus making them ideal for limited footprint applications. They feature a single element which fulfils the need for both overload and short-circuit protection. The high-speed fuses by Bussmann are UL-listed and IEC-certified and offer mounting capabilities with CH fuse holders. They are available in current ratings ranging from 10 to 1000 A at 700 VAC / VDC and interrupt rating of 200 kA at 700 VAC. Choose from a wide range of these high-speed fuses, available in bolt-on or cylindrical body stylies on Raptor Supplies.
