Accessories: 0031.1812 Application Field and Working Principle

0031.1812 is a kind of electrical accessories in industrial control system, which is usually connected between the control switch and the power switch. It can detect overloads and short-circuits and then cut off the power supply system within milliseconds.

Application Field and Working Principle of 0031.1812

The application field of 0031.1812 is mainly used in the power system and other industrial control systems. The working principle of it is based on the electromagnetic induction. When an overload or short-circuit fault occurs, the inductive shield of the 0031.1812 will generate a magnetic field, which will be conducted to the inductance frame of the main circuit. At this time, the main circuit will produce a large current and this large current will be cut off within a few milliseconds through the disconnecting device.
