RK1 fuses are extremely current-limiting fuses meaning they  
greatly reduce or eliminate damage to circuits and equipment under  
short-circuit conditions. Replacing existing Class H, K and RK5 fuses  
with RK1 fuses is one of the easiest ways to immediately improve  
the protection of plant workers and equipment.
