Introduction

The IELK111-29206-1-V (hereafter called IELK111) is a circuit breaker designed to protect electrical systems from overloading or short circuit conditions. This breaker offers a high level of protection in circuits where a neutral line may be present. The IELK111 is a type 2 differential protection circuit breaker, making it suitable for both full-load and over-load protection.

Application Field

The IELK111 is mainly used in industrial, institutional, and commercial facilities, and can be used to protect circuits such as pumps, air conditioning units, refrigeration systems, and other electrical equipment and systems. It is also suitable for use in low-voltage motor control, lighting, and power distribution panels.The IELK111 is primarily designed to protect electrical systems from overloads and short circuits that can cause damage or potentially hazardous situations. The breaker is effective in circuits with neutral lines, as it offers type 2 differential protection, allowing it to detect even subtle changes in current and voltage. In addition, the breaker is designed to trip off in less than one-half cycle of AC current, allowing it to protect pumps and other equipment from harmful surge currents that may be caused by motor starting.

Working Principle

The IELK111 has a trip mechanism that responds to over-current and short-circuit conditions, allowing it to quickly disconnect the power to the circuit. The breaker works by measuring the magnetic or current footprints of voltage and current fluctuations. If the measured magnetic or current footprints exceed a predetermined level, the trip mechanism is activated, and the breaker disconnects the power within less than one-half cycle of AC current.The IELK111 has a manual reset option, which allows users to manually reset the breaker after a faults occurs. This prevents unnecessary trips from happening, and is useful for industrial and commercial applications.The IELK111 also features surge protection features, allowing it to protect delicate instruments against voltage spikes caused by a fault occurring elsewhere in the system. This protection means that only the instrument at risk is affected, instead of disrupting an entire electrical system.The IELK111 is effective in extreme temperatures, and is rated for use from –25°C to 40°C. This makes it suitable for outdoor installations and applications where harsh weather conditions can be expected.

Conclusion

The IELK111 is a type 2 differential protection circuit breaker, designed to protect electrical systems from overloads and short circuits. It is mainly used in industrial, institutional, and commercial facilities, and can be used to protect pumps, air conditioning units, refrigeration systems, and other electrical equipment. The IELK111 features a manual reset option, allowing for more efficient protection, and also includes surge protection features, allowing it to protect delicate instruments from voltage spikes. The breaker is rated for use in extreme temperatures, making it suitable for outdoor installations.
