Circuit breakers are used to protect electrical circuits from overheating and other potential damages due to excessive current. The LEGH66-1-61F-20.0-A-01-V is an example of such a circuit breaker, with an application field and an associated working principle.

The LEGH66-1-61F-20.0-A-01-V has a wide application field, which includes motor control, lighting control, renewable energy and distributed generation. It can be used to regulate current in any type of application, from low voltage circuits to high voltage sources. The device can be used to protect electrical installations from overvoltage, undervoltage, overload, short circuit and ground fault conditions.

The LEGH66-1-61F-20.0-A-01-V has a working principle based on electromagnetism. When the current flow in a circuit rises beyond the specified level, an electromagnetic relay is trigged, which closes the electrical connection, thus cutting off the excessive current. The current flow is then redirected to a secondary circuit, reducing the load on the primary circuit. This protects the primary circuit from overheating and other damages due to excessive current.

In addition to protecting circuits from overheating, the LEGH66-1-61F-20.0-A-01-V also prevents the circuit from being overloaded. This is done through a special mechanism that uses a differential current protection scheme. This allows the device to detect any difference in the current flow of a circuit, and then intervene to prevent the circuit from overloading.

The LEGH66-1-61F-20.0-A-01-V has a number of benefits in terms of its application field and working principle. It is capable of providing reliable protection from overvoltage, undervoltage, overload, short circuit and ground fault conditions. It also offers a mechanism for detecting any difference in current, providing a level of protection that is not possible with other types of circuit breakers.

In summary, the LEGH66-1-61F-20.0-A-01-V circuit breaker is an effective device for protecting electrical circuits from overcurrent, overvoltage, undervoltage and overload conditions. Its working principle is based on electromagnetism, which allows it to detect any difference in current flow and intervene to prevent the circuit from overloading. Its wide application field makes it suitable for many applications, offering reliable protection from a range of conditions.
