The GV2-S21C circuit breaker is a switching device that can turn on, carry and turn off the current under normal loop conditions, and turn on, carry and turn off the current under abnormal loop conditions within a specified time. Circuit breakers are mainly used in power systems, such as high and low voltage distribution systems and motor control systems, as control and protection devices. When short circuit, overload, undervoltage and other faults occur in the line or equipment, the circuit breaker can automatically cut off the circuit to prevent the expansion of the accident and ensure safe operation.

According to the range of use, GV2-S21C circuit breakers can be divided into high-voltage circuit breakers and low-voltage circuit breakers. High-voltage circuit breakers are used for the control and protection of high-voltage power systems, while low-voltage circuit breakers are used for the control and protection of low-voltage distribution systems and motor control systems.

In the low-voltage circuit breaker, also known as the automatic air switch, can be used to switch on and off the load circuit, but also can be used to control the infrequent start of the motor. Its main contact is manually operated or electrically closed, when serious overload or short circuit occurs, it will automatically cut off the circuit.

In addition, the GV2-S21C high-voltage circuit breaker needs to break high voltage and a large amount of current arc, such as 1500V, 1500-2000A arc. These arcs can be stretched to 2m and still continue to burn, so arc extinguishing is a problem that high voltage circuit breakers must solve.
