Circuit breakers are devices designed to protect electric circuits from damage caused by power surges and other potentially dangerous overloads. One type of circuit breaker is the 1C2UR application field and working principle. It is designed to detect power overcurrents, such as those caused by short circuits.

The 1C2UR application field and working principle operates as an automatically operated electric switch. When an overload occurs, the switch closes, disconnecting the circuit and preventing it from being damaged. The switch is designed to be opened automatically if the overload condition is removed, allowing the circuit to be re-established without operator intervention.

The 1C2UR has one or more protected circuits, which are connected to a single control unit that contains a temperature sensor and two switching contacts. When operating normally, the control unit senses the temperature in the protected circuit and opens the switch when it detects an overload. The switch then closes again when the overload is removed.

The 1C2UR is designed to provide short-circuit protection and it can be used in residential and commercial applications. The 1C2UR works by sensing the voltage across the load, which is connected to the protected circuit, and opening the switch if the voltage exceeds a preset level. This is known as the cut-off limit and it is usually set at a level that is slightly higher than the normal operating voltage of the load.

The 1C2UR can be used to protect against overloads caused by excessive current, such as those caused by short circuits, or other over-voltage conditions. When an over-voltage condition is detected, the 1C2UR switch opens and disconnects the circuit, preventing it from being damaged. If the over-voltage condition is removed, the switch will automatically close, allowing the circuit to be re-established without operator intervention.

The 1C2UR is also designed to provide protection against under-voltage conditions. This occurs when the voltage in a circuit is too low, which can cause equipment to fail. By detecting this condition, the 1C2UR switch disconnects the load, thereby preventing any possible damage.

In summary, the 1C2UR application field and working principle provides short-circuit protection, as well as detection of over-voltage and under-voltage conditions. It is designed to detect power overcurrents and other potentially dangerous overloads, and disconnect the circuit in the event of an overload or abnormal voltage condition. The 1C2UR switch is designed to be automatically re-established when the overload or abnormal voltage is removed.
