Overload protection (generally, distribution lines do not need overload protection, but can be used as backup protection for short-circuit protection of the next-level power equipment)
Overload protection action current Id2=Kk2 Ijs
Where: Ijs—working current (calculated current) of the protected line (A)
Kk2—reliability coefficient, generally 1.1
Id2—Lv Pole Mounted Circuit Breakers long-delay release setting current (A)
