Product Description

The A70QS high-speed semiconductor fuse is engineered for use in equipment requiring reliable protection at 700V. With an ampere rating of 800 A, it features a low I²t value which enhances its protective capabilities, providing longer operational life even under cyclic loads.

Additionally, this fuse minimizes power loss during operation, making it suitable for applications such as motor drives and uninterruptible power supplies (UPS). The fuse is constructed from a GMG insulating material and is equipped with bolted connections made of tin-plated copper, ensuring robust electrical integrity. With a maximum operating temperature of 80 °C and a breaking capacity of 40 kA, the A70QS is a reliable choice for protecting sensitive electronic systems.
