The original IEC 60127-4 Universal Modular Fuse, series UMT 250, is offered in a convenient package to simplify fuse replacement. The fuse and fuseholder combination, dubbed the UMZ 250, provides high performance overcurrent circuit protection in primary or secondary circuits. The compact and leadless unit also provides assembly advantages over conventional through-hole fuse blocks and clips. The low profile facilitates increased production speed, especially with assembly processes using automated pick and place systems. Current ratings for the fuse with fuse clips range from 0.315 mA to 4.0 A. The stand-alone fuse UMT 250 includes twenty two current ratings, ranging from 80 mA to 10 A. Voltage ratings are 250 VAC and 125 VDC according to IEC and 277 VAC and 250 VDC according to UL.
