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)

Product and installation dimensions(MM)
