Circuit breakers are designed to protect wires and electrical installations from damage due to overcurrent, and are widely used in residential, commercial, and industrial buildings. The LEGH66-1-63-30.0-01 circuit breaker is a common example of this type of protection device.

Application Field

The LEGH66-1-63-30.0-01 is a type C circuit breaker manufactured by the company CEE SA which is designed to protect electrical circuits with a current rating of 30.0 Amps (A). This type C circuit breaker is suitable for use in single-phase circuits and 3-wire plus neutral DC installations. This device is commonly used in residential, commercial, and industrial applications as well as in public transportation systems.

Working Principle

This type C circuit breaker operates on the principle of electromagnetic force. When the current flowing through the device exceeds its rated limit, an electromagnet embedded in the device is activated, causing a force to be applied on a switching mechanism. This switching mechanism is designed to disconnect the circuit, thus protecting it from damage due to overcurrent.

The LEGH66-1-63-30.0-01 also has an overload protection feature which prevents the circuit from being damaged due to extended periods of overcurrent. This feature is activated by a thermal element which will cause the circuit breaker to disconnect the circuit when the temperature of the device reaches a predetermined level. Besides, this device also has a manual reset button which can be used to manually reset the device after it has been activated by an overcurrent.

In addition to the overload protection, the LEGH66-1-63-30.0-01 is also equipped with short-circuit protection. This feature is activated by an electronic element which will detect an imbalance in the current flow through the device and then interrupts the current flow before it can cause any damage to the system.

Conclusion

The LEGH66-1-63-30.0-01 circuit breaker is a type C device widely used in residential, commercial, and industrial applications to protect electrical installations from damage due to overcurrent. This device operates on the principle of electromagnetic force and is equipped with both overload and short-circuit protection. This makes it a reliable and effective way to protect electrical systems from the risks associated with overcurrent.
