Tripping Characteristic Curves
• IEC60898-1 Standard
| • Magnetic release An electromagnet with plunger ensures instantaneous tripping in case of short circuit. The IEC 60898 distinguishes three different types, following the current for instantaneous release: type B, C, D

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
-The release is initiated by a bimetal strip in case of overload
-The standard defines the range of release of specific overload values
-Reference ambient temperature is 30°C

• IEC60947-2 STANDARD
| • Magnetic release -An electromagnet with plunger ensures instantaneous tripping in case of short circuit. -The standard leaves the calibration of magnetic release to manufacturers decision. -LWBX offers instantaneou's tripping ranges -release B: 4ln -release C: 8ln -release D: 12ln |
• Thermal Release
-The release is initiated by a bimetal strip in case of overload
-The standard defines the range of release for two specific overload values -Reference ambient temperature is 30°C for LWBX
