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.

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.
