Glass, cylindrical, system D and knife fuses. Luminaires and sockets as well as fuse bases and switch disconnectors. A comprehensive offer of protections fully adapted to the needs of professional power engineering and various industries. In order to meet the expectations of the customer, Hager has introduced two trip signaling solutions for NH fuses. Fuses with an upper trip indicator are mainly intended for fuse bases, where the visibility of this indicator is good due to the lack of covers. Fuses with a double combined indicator are designed for fuse switch disconnectors. The indicator, which is located on the front plate of the porcelain body, is perfectly visible in the inspection windows that have fuse switches. Using such a solution significantly shortens the time of locating a damaged fuse.
