Mersen Q204944 MISIPTF20 SI PTF 20 open-type miniature fuse holder for replaceable cartridge fuses used in electrical, electronic and industrial equipment.
Why Choose the Mersen Q204944 SI PTF 20 Miniature Fuse Holder?
The Mersen Q204944, catalogue reference MISIPTF20, is a compact open-type miniature fuse holder designed to provide a secure mounting point for a replaceable cartridge fuse within electrical and electronic equipment. Also described as the SI PTF 20, it offers a practical circuit-protection solution for control assemblies, power supplies, instrumentation and OEM products.
The Q204944 enables a compatible fuse link to be incorporated directly into an equipment assembly, helping protect connected circuits against overloads and short circuits. Its open construction provides straightforward access to the installed fuse, supporting convenient inspection, testing and replacement during servicing.
Manufactured by Mersen for professional electrical applications, this miniature fuse holder is suitable for use inside protected equipment and enclosures. Its compact format makes it particularly useful where installation space is limited but accessible, replaceable fuse protection is required.

Accessible Fuse Protection for Electrical Equipment
The Mersen Q204944 provides a secure interface between a protected electrical circuit and a replaceable miniature fuse link. When the installed fuse operates because of an overload or short circuit, the open holder design allows maintenance personnel to inspect and replace it without changing the permanent equipment wiring.
Because the holder is open and does not prevent access to the fuse or electrical contacts, it should be fitted within appropriately enclosed equipment. This makes it suitable for manufacturers and panel builders requiring compact fuse protection inside assemblies that already provide the necessary protection against accidental contact.
