Small UMT-H surface mount fuse Rated current up to 50A

Schurter's UMT-H surface mount ceramic fuse series product quality, currently adding a model of rated current to 40A and 50A, with rated breaking capability as up to 500A at 125VAC / 72VDC. The series provides overcurrent and short-circuit protection features for the first time, and the structure is compact, and the product size is only 5.3 x 16mm. The R & D of the UMT-H series fuse is to provide a small size alternative to a through hole for 5x20 mm, which is usually used for main circuit protection. Currently, the UMT-H series has covered 26 rated currents from 160mA to 50A. The maximum value of the rated voltage is 277 VAC / 250 VDC, the rated current is up to 6.3A, and the rated breaking capacity can be up to 1500A. The delay characteristics of the UMT-H series fuse allow it to be resistant to high surge and pulse current. UMT-H series products have been evolved, and the rated current has been launched to be highly protected in battery power supply applications. The product application field is very wide, from the engine to various emerging applications that depend on the accumulator and various conventional applications. UMT-H provides a comprehensive ideal solution for many applications in energy, data, medical, industrial control, and automotive and other industries. This series of products does not penetrate the plastic coatings, so it is ideal for ATEX and IECEX certification equipment applied in hazardous environments. Multiple breaking capability measurements were performed on UMT-H according to a particular welding width. The ambient temperature allows range to -55 ° C to 125 ° C. The larger pad ensures the best heat dissipation. UMT-H is designed according to IEC 60127-7 and UL 248-14, VDE and CURUS certification have also been tested by IEC, MIL-STD 202, and AEC-Q200.
