Tripping Characteristic Curves

IEC 60898-1

L7 Miniature Circuit Breaker

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 L7 miniature circuit breaker 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.
