SIBA, 2003120.250, 250A Knife-Blade fuses, URM Series, BOX OF 2

MODEL: 2003120.250

Highly specialized, industrial-grade knife-blade contact HRC fuse engineered specifically for demanding high-voltage DC applications. Part of SIBA’s high-performance 20 031 20 family, this specific model features a continuous current capacity of 250 Amps and is dual-certified under the gPV and gR operating classes.

Constructed within a massive, hermetically sealed NH3L (Size 3 Long) ceramic body to handle substantial physical and electrical loads, this fuse provides reliable protection against high-fault energy arcs up to 1000VDC. Unlike typical electrical fuses, the specialized internal matrix of this 250 Amp fuse is explicitly designed to clear low-level DC string or inverter faults rapidly without suffering from premature thermal fatigue under cyclic loads
