Footprint of 5.3 x 16 mm conserves board space.
Original Press Release:
New Rated Current Values for SCHURTER's Compact Higher-Performance UMT-H Fuse
Santa Rosa, California – SCHURTER expands its UMT-H series, adding new current ratings 20 A, 25 A and 30 A. The addition of the higher current ratings provide the widest range of currents in its compact SMD form factor, totaling 24 rated currents between 160 mA and 30 A at varying voltages up to 277 VAC and 250 VDC.
SCHURTER announces VDE and UL approvals for its SMD fuse with 1500 A breaking capacity.
Compact, high performance fuse is optimal for intrinsically safe applications.
SCHURTER's UMT-H offers a 1500 A breaking capacity at rated voltages of 277 VAC / 250 VDC. The compact, high performance fuse now has VDE approval in addition to UL approval. This time-lag fuse provides overcurrent and short circuit protection in various industrial control applications, including intrinsically safe applications.
The "intrinsic safety" method is one of the most common techniques used for achieving safety protection with lower voltage or power equipment. This method restricts the available electrical and thermal energy in a system so that ignition of a hazardous atmosphere (such as explosive gas, dust, or electrical arcing) cannot occur. The UMT-H's high breaking capacity of 1500 A, plus the >10 mm spacing between end caps, combined with the ability to be impermeable to conformal coating makes the fuse suitable for use in such intrinsically safe applications.
The UMT-H fuse is available in a total of 24 rated currents between 160 mA and 30 A at voltages up to 277 VAC and 250 VDC. The UMT-H measures at 5.3 x 16 mm, which is a smaller alternative to the classic cylindrically-shaped cartridge fuses (e.g. 5 x 20 mm). The smaller footprint saves valuable board space, allowing for further downsizing of equipment. With its square design, the UMT-H is also suited for more cost-effective, automated assembly. The high breaking capacity fuse meets the IEC 60127-7/1, UL 248-14 and CSA C22.2 standards along with its VDE and UL approvals. Additional applications include power supplies, electromobility, medical and telecommunication applications as well as 277 VAC utility-connected equipment.
