Why Choose the Mersen A204953 Miniature Fuse Holder?
The Mersen A204953, catalogue reference MIPUPTF70, is a robust panel-mounted miniature fuse holder designed for use with standard 5 × 20 mm cartridge fuses. As part of the Mersen protected PU PTF series, it provides a secure and accessible circuit-protection solution for industrial control equipment, electronic assemblies and electrical panels.
Rated at 250 V AC and 10 A, the A204953 uses a practical bayonet cap that allows straightforward fuse installation and replacement. Its single-pole construction and compact cylindrical body make it suitable for equipment where space is limited but dependable fuse retention and electrical contact are essential.
The fuse holder features a durable PA6 insulating housing, an IP40 protection rating and materials meeting the UL94 V-0 flammability classification. Low contact resistance helps maintain efficient electrical performance, while compliance with IEC miniature fuse-holder requirements supports reliable use in professionally designed electrical and electronic equipment.
