Circuit Breakers are essential components in electricity powered systems. LEG66-36386-2-V, is one type of circuit breakers, which have various applications and working principles.

The LEG66-36386-2-V circuit breaker is designed for use in direct current (DC) power systems, up to 1000V, with a rated current up to 63A. This breaker is compliant with the international IEC 60947-2 Standard, providing protection for low voltage installations. It is most suitable for protection against short-time circuit delays, electrical surges and overloads.

The LEG66-36386-2-V provides a wide range of applications in critical process control power systems, such as large industrial motor operations, solar farm operations, plus numerous other commercial applications. It is suitable for safety of personnel by disconnecting the load from the mains at a pre-set current value. It is also suitable to protect equipment against overload and short-circuits, helping to ensure that the operation is as safe and secure as possible.

The LEG66-36386-2-V circuit breaker operates in two modes: the thermal mode and the magnetic mode. In thermal mode, the temperature of the bimetal in the circuit breaker, increases gradually due to high current. When the temperature reaches to a specific threshold value, the bimetal bends and trips the breaker. The reset operation is performed manually or automatically, depending on the application requirement.

In magnetic mode, a magnetic field is generated when a fault current passes through the iron core. This magnetic field causes an armature to move rapidly, generating a mechanical force on the movable contact-trip spring. The spring trips the breaker open rapidly to protect the circuit from further overheating and damage. In this mode, the reset starts with manual operation.

The LEG66-36386-2-V circuit breaker is especially designed to meet high performance requirements. Its double breaking configuration increases its short-circuit current breaking capacity and its breaking sensitivity. This ensures better safety during operation. It also has an intelligent control system, which constantly monitors the current on the circuit, and trips the breaker when a risk arises.

This circuit breaker is constructed with a fire-safe insulated housing, and is easy to mount and maintain. An LED indicator indicates the status of the breaker, such as its trip level, test status or mechanical tests, even in noisy environments. It can also be part of a larger system, communicating and providing information to other components.

In conclusion, LEG66-36386-2-V is ideal for use as a protective device for DC power systems. It provides superior protection against short-circuits, electrical surges and overloads, whilst being easy to use and maintain. It is perfect for a wide range of applications, including process control power systems, industrial motor operations, plus many more commercial applications.
