●Tripping Characteristic Curves
IEC 60898-1
●Magnetic Release
When a circuit short circuit occurs, instantaneous tripping is achieved by a magnet with an iron core. According to the 1EC60898 standard, this product can be divided into three types: B, C, and D.
Test current | Tripping time | Applications | |
B Curve | 3ln | 0.1<t<45s(In ≦ 32A) | Type B is only applicable to active loads: |
C Curve | 5In | 0.1<t<15s(In ≦ 32A) | Type C is suitable for ordinary loads: |
D Curve | 10ln | 0.1<t<4s(In ≦ 32A) | Control and protect circuits with instantaneous surge current |
● Thermal Release
●Once overload occurs in the circuit, the bimetallic strip of the circuit breaker will bend due to heat, causing the contacts to disconnect and resulting in
thermal tripping;
●The IEC standard defines the tripping time range for different overload currents;
●The reference test environment temperature is 30 °C.
Test current | Tripping time |
1.13ln | t z 1h(in ≦ 63A) |
1.45ln | t<1h(In ≦ 63A) |
2.55ln | 1s<1h<60s(In≤32A)1s<t<120s(In>32A) |
