One of the main functions of the circuit breaker is to provide open and closed current carrying contacts. Although it seems to be quite simple. However, it should be remembered that a circuit breaker remains in its closed position for its longest life span. Very occasionally it needs to be used to open and close its contacts to operate the circuit breaker. Therefore, the operation of the circuit breaker must be very reliable without any delay or sluggishness. In order to achieve this reliable circuit breaker operating mechanism becomes more complex than its first thought. The opening and closing contact and the distance between the moving contact speeds during operation, as well as the stroke, are the most important parameters to consider in the design of the circuit breaker. The contact gap, the distance traveled by the moving contact and its speed are determined by the type of interrupter medium, the current and the rated voltage of the circuit breaker. A typical circuit breaker operating characteristic curve is shown in the following figure. Here, in the figure, the X-axis represents the distance in milliseconds and millimeters per second and the y-axis.
Miniature circuit breakers - Uncompromising safety and comfort
Ebasee MCB's are among the best available designed with proven, trusted and reliable German Technology to provide enhanced operating safety, Installations for domestic, commercial and industrial applications. Some of the salient features of these MCB's are as below.
Miniature Circuit Breaker (Miniature Circuit Breaker), also known as micro-circuit breaker (Micro Circuit Breaker), is a suitable for home or similar places overcurrent protection circuit breaker (hereinafter referred to as MCB), previously known as wire protection switch ).
Miniature Circuit Breaker or MCB,Nowadays we use more commonly miniature circuit breaker or MCB in low voltage electrical network instead of fuse. The MCB has some advantages compared to fuse.
