Mersen A50QS Amp-Trap High Speed Fuse, 500VAC/500VDC Rated

Mersen A50QS Amp-Trap High Speed Fuse, 500VAC/500VDC Rated

The Mersen A50QS Amp-Trap® High Speed Fuse, 500VAC/500VDC Rated is a Form 101 semiconductor fuse engineered to protect dynamic solid-state equipment such as motor drives, inverters, and UPS systems. Rated 500VAC and 500VDC (UL) with a high-speed characteristic at 50/60 Hz, the A50QS delivers a lower I²t let-through for improved equipment protection, longer service life when subjected to cyclic loading, and lower watts loss compared to earlier semiconductor fuse designs. It is RoHS compliant and packaged 20 fuses per box for professional electrical and industrial supply applications.

Key Features

• High-Speed Protection: High-speed characteristic engineered for fast clearing of fault currents in semiconductor circuits.
