Circuit breakers are devices essential in any electric network and are used to prevent electric currents from exceeding normal maximum levels. The IELR1-34003-1-V is a type of circuit breaker that is used in different applications as well as in different voltage classes. This article will discuss its applications as well as its working principles.

Application field

The IELR1-34003-1-V is a mini circuit breaker commonly used in domestic and commercial installations. It can be used in single, two and three-phase electric networks running with AC voltage up to 415V. This breaker is certified for most European Union countries and is approved for operation in electric networks with frequency of up to 50/60 Hz.

Besides causing short circuits and overloads, the IELR1-34003-1-V breaks electrical currents when working in electric circuits operating higher currents than the rated value. This breaker can be used to protect overload and short circuits in machines, domestic and commercial premises, industrial facilities or commercial buildings and other applications.

Working Principle

There are two main components of the IELR1-34003-1-V circuit breaker – an electromagnetic device and an electric trigger. When the current passing through the circuit is higher than the rated value, the electric trigger sends a signal to the electromagnetic device which sends a magnetic field to the output. This field will cause a contact breaker at the other end of the cable and the current in the circuit is interrupted.

The IELR1-34003-1-V features a current limiting setting which trips the breaker if the current is greater than a predetermined value. The setting can be adjusted to trip before reaching the current limit of the circuit, thus preventing any damage.

The circuit breaker is effective for most AC current applications in both continuous and quick flow operation. The current limit is adjustable, therefore it can prevent over current in various operating conditions. Additionally, the IELR1-34003-1-V can be installed in any position, regardless of the angle of the power supply, as it is designed to hold all current types and features a built-in overvoltage protection.

Conclusion

The IELR1-34003-1-V is a mini circuit breaker which is used in single, two and three-phase electric networks for up to 415V, and can be used to protect overloads and short circuits across various applications. It has a current limiting setting which trips the breaker before reaching the maximum rated current of the circuit and it is effective in most AC current applications.
