Ultra-fast fuse link CH22 AR 63A / 690V 002645021

Ultra-fast fuse link for semiconductor protection

This CH22 aR 63A / 690V fuse link from ETI Polam is a reliable safety element for electrical installations, especially those containing sensitive semiconductor devices. Its design and parameters ensure quick and effective protection against the effects of short circuits and overloads.

The fuse link is characterized by a high short-circuit breaking capacity – up to 200kA in AC and 50kA in DC. This minimizes the risk of damage to connected devices and ensures the safety of the entire system in the event of a failure. The aR characteristic makes it ideal for circuits with high starting currents, allowing for a quick response to sudden load changes.

Features and application

The CH22 fuse link is designed to protect circuits powering semiconductor devices such as inverters, rectifiers, and switch-mode power supplies. Its compact dimensions (22x58 mm) allow for installation in limited spaces. It meets the requirements of IEC 60269-4, guaranteeing its safety and reliability.
