Circuit Breakers

Circuit breakers are a type of switching device used to protect electrical circuits from overloads and short circuits. The IEG6-1-51-20.0-01-V is a type of circuit breaker designed for low-voltage applications including residential, commercial, and industrial installations.

Application Field

The IEG6-1-51-20.0-01-V circuit breaker is designed for use in light-industrial and commercial applications, as well as in single-family dwellings, multi-family dwellings, and institutional building installations. It can be used to protect AC circuits in the range of 15A to 100A in single-phase or three-phase installations.

Working Principle

The IEG6-1-51-20.0-01-V circuit breaker is a thermal-magnetic type device. This means that it is equipped with both a thermal element (a bimetallic strip) and a magnetic element (an electromagnet). When an overload or short circuit occurs, the thermal element responds first, by rapidly increasing its resistance. This causes the current to be diverted from its normal path, forcing the contacts inside the circuit breaker to open.

At the same time, the magnetic element creates a field that acts on the moving armature inside the circuit breaker, pushing it towards the open position. This ensures that the contacts stay open even after the thermal element has returned to its normal temperature. In addition, the magnetic element is also responsible for resetting the circuit breaker after the fault has been cleared.

Safety Features

The IEG6-1-51-20.0-01-V circuit breaker is UL 489 listed and features a number of safety features that improve the protection of electrical circuits. The circuit breaker is equipped with a shunt-trip device, which can be used to trip the circuit breaker remotely in the event of an emergency or abnormal operating condition. The IEG6-1-51-20.0-01-V is also equipped with a thermal-magnetic trip unit that provides protection against low-level overloads, short circuits, and ground faults.

Advantages

The IEG6-1-51-20.0-01-V circuit breaker offers several advantages compared to other types of low-voltage circuit breakers. It has a high interrupting rating of up to 10kA, making it suitable for protecting circuits with high electrical loads. The circuit breaker also has a small footprint, making it suitable for installations where space is at a premium. Additionally, the circuit breaker can be used with a wide range of power sources, including 120V, 240V, and 480V AC sources.

Conclusion

The IEG6-1-51-20.0-01-V circuit breaker is a versatile and reliable electrical protective device that is suitable for use in a wide range of applications. Its small footprint, high interrupting rating, and range of safety features make it an excellent choice for protecting electrical circuits in residential, commercial, and industrial installations.
