L7-10/2/C 断路器是一种开关装置，能够关合、承载和开断正常回路条件下的电流，并在规定的时间内关合、承载和开断异常回路条件下的电流。断路器主要应用于电力系统，如高低压配电系统和电动机控制系统，作为控制和保护装置。当线路或设备发生短路、过载、欠压等故障时，断路器能够自动切断电路，防止事故扩大，保证安全运行。

根据使用范围，L7-10/2/C断路器可以分为高压断路器和低压断路器。高压断路器用于高压电力系统的控制和保护，而低压断路器则用于低压配电系统和电动机控制系统的控制和保护。

在低压断路器中，也称为自动空气开关，可用来接通和分断负载电路，也可用来控制不频繁起动的电动机。它的主触点是靠手动操作或电动合闸的，当发生严重过载或短路等情况时，会自动切断电路。

此外，L7-10/2/C高压断路器需要开断高电压和大量电流的电弧，例如1500V、1500-2000A的电弧。这些电弧可拉长至2m仍然继续燃烧不熄灭，因此灭弧是高压断路器必须解决的问题。

L7-10/2/C SCHNEIDER Circuit breaker

The L7-10/2/C circuit breaker is a switching device that can turn off, carry and break the current under normal loop conditions, and turn off, carry and break the current under abnormal loop conditions within a specified period of 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 scope of use, L7-10/2/C 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, L7-10/2/C high-voltage circuit breakers need 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.
