Mersen A50QS275-4IL

The A50QS Amp-Trap® Form 101 fuses were developed to enhance the performance of semiconductor fuses in line with evolving equipment demands. This model features an optimized I₂t rating, which ensures superior protection for equipment while extending lifespan under cyclic loads and minimizing energy loss. The A50QS is particularly suited for safeguarding dynamic solid-state devices, including motor drives, inverters, and uninterruptible power supplies (UPS).

With a maximum operating temperature of 80 °C and a storage temperature range from -25 °C to 80 °C, this fuse maintains reliability across varying environmental conditions. It operates at an ampere rating of 275 A and is rated for both AC and DC voltages up to 500 V. The high-speed characteristic of the A50QS ensures rapid response to overcurrent situations, thereby providing critical protection for sensitive electronic components.
