This product complies with Type B of IEC 60898-1 standard, The characteristics of the C-type and D-type
trip curves.
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 5ln |
0.1<t<45s(In <= 32A) 0.1<T<90s(In>32A) |
Type B is only applicable to active loads: -Electric heater-Water heater-Electric furmace |
| C Curve | 5In 10ln |
0.1<t<15s(In <= 32A) 0.1<T<30s(In>32A)t<0.1s |
Type C is suitable for ordinary loads: -Lamp -Power socket -Small power motor |
| D Curve | 10ln 20In |
0.1<t<4s(In <= 32A) 0.1<T<8s(ln>32A) t<0.1s |
Control and protect circuits with instantaneous surge current (large motors) |
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) |
The product is mounted on a guide rail with a maximum connection capacity of 25mm2.
