TEST CURRENT | TRIPPING TIME | APPLICATIONS | |
B | 3 In 5 In | 0.1<t<45s(ln<32A) 0.1<t<90s(ln>32A) t<0.1s· | Only for resistive loads such as: -electrical heating -water heater -stoves loads such as |
C | 5 In 10 In | 0.1<t<15s(ln<32A) 0.1<t<30s(ln>32A) | Usual loads such as: -lighting -socket outlets -small motors |
D | 10 In 20 In | 0.1<t<4s(ln<32A) 0.1<t<8s(ln>32A) t<0.1s | Control and protection of circuits having important transient inrush currents (large motors) |
• Thermal Release
