SCHURTER announces VDE and UL approvals for new SMD fuse

SCHURTER offers a new Universal Modular fuse, UMT-H, with a 1500 A breaking capacity at rated voltages of 277 VAC and 250 VDC. The compact, high performance fuse now has VDE approval in addition to UL approval.

SCHURTER offers a new Universal Modular fuse, UMT-H, with a 1500 A breaking capacity at rated voltages of 277 VAC and 250 VDC. The compact, high performance fuse now has VDE approval in addition to UL approval. This time-lag fuse provides over-current 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 greater than 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 according to the 60079-11 International Electrotechnic Commission (IEC) standard.

The UMT-H fuse is available in a total of 19 rated currents between 160 mA and 10 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. 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.
