Product Description

The A50QS Amp-Trap® Form 101 fuse is designed to enhance the performance of semiconductor fuses in alignment with evolving equipment demands. It integrates advanced protection capabilities, including a lower I²t rating that safeguards equipment more effectively, an extended lifespan under cyclic loading, and reduced watt loss. This model is particularly suited for the protection of dynamic solid-state devices, such as motor drives, inverters, and uninterruptible power supplies (UPS). The fuse operates within a maximum temperature of 80 °C and is capable of handling rated voltages of 500V AC and 500V DC. With a breaking capacity of 63 kA, it ensures reliable protection against overloads and faults.

Constructed with a diameter of 1.5 inches, the A50QS features a body insulating material made of GMG and tin-plated copper for its connection terminals, which are designed for bolted mounting. This product, designated as A50QS IL, represents the optimal choice for safeguarding sensitive electronic equipment in various industrial applications.
