## Long description

The Eti-Polam CH22UQ is a high-performance cylindrical fuse link engineered for robust electrical protection in industrial environments. Measuring 22x58mm, this component is specifically designed to handle high-current applications, offering a rated current of 100A and a voltage rating of 690V AC. As an aR class fuse, it is optimized for the rapid protection of semiconductor devices, such as diodes, thyristors, and power electronics, against short-circuits and overloads.
Advantages
This fuse link stands out due to its specialized aR characteristic, which ensures extremely fast response times during fault conditions, thereby minimizing potential damage to sensitive power electronic components. Its compact cylindrical design allows for efficient space utilization within electrical cabinets and fuse holders. The high breaking capacity and reliable construction ensure consistent performance even under demanding industrial conditions, contributing to the overall safety and longevity of complex power systems.
Suitable for
Semiconductor protection
Power electronics systems
Industrial control panels
Frequency converters and soft starters
Rectifier circuits
This fuse is not intended for general-purpose residential circuit protection or for applications where a slow-blow characteristic is required to handle high inrush currents. It is strictly designed for fast-acting semiconductor protection and should not be used in circuits exceeding its rated voltage or current specifications.
Key specifications
Dimensions: 22x58mm
Rated current: 100A
Rated voltage: 690V AC
Fuse class: aR (semiconductor protection)
Body type: Cylindrical
How to use
The fuse link should be installed into a compatible 22x58mm cylindrical fuse holder or disconnect switch. Ensure that the power supply is completely disconnected before attempting to insert or replace the fuse. Align the fuse correctly within the holder clips, ensuring a firm and secure connection to prevent overheating due to contact resistance. Once installed, verify that the fuse holder is properly closed and secured before restoring power to the system.
What to consider before purchase
Verify that the current and voltage ratings match your specific circuit requirements.
Ensure the fuse holder is compatible with the 22x58mm form factor.
Confirm that the aR characteristic is appropriate for the equipment being protected.
Check for sufficient clearance in the electrical panel for heat dissipation.
Usage recommendations
Always replace the fuse with one of the exact same type, rating, and class to maintain the integrity of the protection system. Never attempt to repair or bypass a blown fuse, as this poses a significant fire and safety hazard.
