Universal Modular Fuses
SCHURTER is extending its family of Universal Modular Fuses to include a version with 1500 A breaking capacity at rated voltages of 277 VAC/250 VDC. The high breaking capacity of the UMT-H makes this time-lag fuse ideal for applications with high short-circuit currents. The UMT-H at 5.3 x 16 mm is a smaller alternative to 5 x 20 mm cartridge fuses with equal technical specifications; saving valuable board space to allow for further downsizing. The convenient position of the device markings immediately shows key information about the fuse such as approvals, current rating and voltages.
The UMT-H is designed for a wide range of applications where a cartridge fuse is used, including primary protection of PCB’s for over current and short circuit protection, sensors and power supplies. The high breaking capacity of 1500A combined with >10 mm spacing between end caps meet IEC 60079-11 for use in applications requiring components for explosion protection, such as first responder equipment, industrial controls exposed to chemical environments, and lighting ballasts. The 277 VAC rating allows for protection of utility connected appliances or equipment. The UMT-H is initially offered with six rated currents from 160 mA to 2 A with future releases of currents up to 10 A. It is cURus approved VDE approval is pending.
