Miniature cylindrical glass fuse link 5X20 T 160 MA/250V 006710004

Compact electronic protection for delicate circuits

The miniature cylindrical fuse link with dimensions 5×20 mm is a reliable protective solution for delicate electronic circuits. Manufactured by ETI-POLAM, it ensures effective protection against overloads and short circuits while maintaining compact dimensions.

Operating parameters and technical characteristics

The device operates with a rated current of 160 mA and an AC voltage up to 250V, making it suitable for a wide range of electronic applications. The time-delay characteristic (T) allows for the passage of short-term inrush currents typical of switching power supplies and control systems, while reacting to long-term overloads.

The glass body enables optical monitoring of the fuse status - in the event of operation, the fusible element becomes visible through the transparent housing, which significantly facilitates fault diagnosis. The compact design allows for mounting in standard CH5 fuse holders.

Areas of application

Thanks to its precise technical parameters, it is used in:

• Switching power supplies and mains adapters
• Industrial automation control systems
• Measuring and monitoring devices
• Teletechnical and teleinformatic installations

Design and operational advantages

The time-delay tripping characteristic eliminates problematic "false" trips during normal operation of electronic devices, while simultaneously providing an immediate response to actual emergency states. The glass housing facilitates visual inspection of the fuse status.

The standard 5×20 mm size guarantees compatibility with widely used CH5 type fuse holders, eliminating the need for specialized adapters or dedicated sockets.
