Boa tarde.
Alguém tem alguma documentação que fale acerca de curvas de disparo "especiais" (Z, K, M (MA)) dos disjuntores (utilização, caracteristicas,etc.) ?
Cumprimentos.

Re: Curvas de disparo "especiais"
Boas,
Tenho algures os gráficos das curvas, num catálogo ou livro não me recordo, entretanto
esta informação já te deve ajudar :
Tripping curves
B curve
When the short-circuit currents are weak (generators, long cables).
Power circuit:
ratings: 6 to 63 A set at 40°C
tripping curve: the magnetic trip units operate between 3.2 and 4.8 In.
C curve
Cables feeding conventional loads.
Power circuit:
ratings: 0.5 to 63 A set at 40°C
tripping curve: the magnetic trip units operate between 7 and 10 In.
K curve
Loads with a high inrush current (motors, transformers).
Power circuit:
rating: 1 to 63 A set at 40°C
tripping curve: the magnetic trip units operate between 10 and 14 In.
Z curve
Protection of electronic circuits.
Power circuit:
rating: 1 to 40 A set at 40°C
tripping curve: the magnetic trip units operate between 2.4 and 3.6 In.
