Ultra-fast fuse link CH22 AR 80A / 600V 002645023

Safety and Semiconductor Protection

The CH22x58 aR 80A/600V fuse insert is an element used to protect electrical circuits, especially semiconductor devices. Its design based on the aR characteristic ensures a quick response to overvoltages and short circuits, minimizing the risk of damage to connected components. This is crucial for installers who need to provide reliable protection for sensitive electronic systems.

Characteristics and Application

Fuse insert with dimensions 22x58 mm, designed to operate at voltages up to 600V and a rated current of 80A. The aR (ultrafast) characteristic makes it ideal for protecting semiconductor circuits that require very fast intervention in the event of a failure. The short-circuit breaking capacity reaches 200kA AC and 50kA DC, guaranteeing effective protection even in the event of high current flows. Power losses are 13.5W, and the total Joule integral is 6.6 A²s.

Key Features and Benefits
