Siemens 150A NH Fuse, NH3, 690 / 440V ac/dc

The Siemens semiconductor fuse protect power semiconductors from the effects of short circuits because the super quick-response disconnect characteristic is far quicker than with conventional LV HRC fuses. It protect expensive devices and system components, such as converters with fuses in the input and the DC link, UPS systems and soft starters for motors.

For the protection of power semiconductors
High varying load factor
High level of operational safety and plant availability
Tested with regard to heat dissipation and maximum current loading
