Circuit breakers are a key safety feature in any electrical installation and they are designed to protect the system from electrical hazards. The LEL 111-32559-3-V is a type of molded-case circuit breaker (MCCB) which is designed specifically for different applications. This article will discuss the application field of this MCCB and its working principle.

Application Field of LEL 111-32559-3-V

The LEL 111-32559-3-V is designed for protection against short-circuit and overload currents and is suitable for circuit protection applications. It can be used for residential, commercial and industrial applications, as well as in motor control centers. It is also suitable for the protection of motors, transformers, generators and overcurrent protection. The maximum current rating of the MCCB is 63A and it has an AC rating of 400V, making it suitable for use in various applications.

Working Principle of LEL 111-32559-3-V

The LEL 111-32559-3-V has two different working principles. The first is based on the inverse time delay (IDT), which is the most commonly used principle in MCCBs. When a short-circuit or overload is detected, the MCCB will trip the circuit based on the current and how long it has been connected. This provides an efficient way of protecting the circuit from electrical faults.

The second principle used in this MCCB is the magnetic overcurrent protection (MOP). This works by monitoring the current in the circuit and using a magnetic field to disconnect the overload circuit if the current exceeds a preset limit. This gives the circuit additional protection against overcurrents.

Conclusion

The LEL 111-32559-3-V is a type of molded-case circuit breaker that is designed for protection against short-circuit and overload currents. It can be used for residential, commercial and industrial applications, as well as for the protection of motors, transformers and generators. The working principle of this MCCB is based on inverse time delay and magnetic overcurrent protection which makes it an effective and efficient device for protection of the electrical system.
