Circuit breakers are divided into high-voltage circuit breakers according to their use range, and low-voltage circuit breakers. The division of high and low voltage lines is relatively vague. Generally, 3kV or more is called high-voltage electrical equipment. Low-voltage circuit breaker, also known as automatic switch, is an electrical appliance that has both manual switching and automatic voltage loss, undervoltage, overload, and short-circuit protection.

Bi Directions Thyristor (Triac)
Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
