Universal modular fuse

20 Jul 2015
SCHURTER’s Universal Modular fuse, UMT-H, offers a 1500A breaking capacity at rated voltages of 277Vac / 250Vdc. 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 1500A, 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 according to 60079-11.
