Circuit Breakers

LEG1-1-63-15.0-A-01-V is a type of circuit breaker which is used in high voltage electricity distribution networks. It is a device which is used to protect electrical circuits from overloading or short-circuiting. It works by disconnecting the circuit when an excess of current flows through it, preventing damage to the circuit components and to people.The LEG1-1-63-15.0-A-01-V circuit breaker is a three-phase circuit breaker which is rated for 15kV and 63A. This type of circuit breaker is ideal for applications where high-voltage and high current are needed, such as industrial and commercial facilities.The main components of this type of circuit breaker are the three-phase trip unit, the trip actuator, the overcurrent protection device, and the main breaker unit. The trip unit is responsible for detecting when the current in the circuit exceeds the set limit and trip the circuit. The trip actuator is used to turn the circuit on or off and reset the system when needed. The overcurrent protection device is used to protect the circuit from overloading by automatically disconnecting the current when it exceeds the set limit. The main breaker unit is the part of the circuit breaker which actually disconnects the circuit from the power supply when an overload or short circuit occurs.The working principle of the LEG1-1-63-15.0-A-01-V is that when a current that exceeds the set limit passes through the circuit, the trip unit senses the increased current and triggers the trip actuator to turn off the circuit. The overcurrent protection device then trips the main breaker unit to fully disconnect the power from the circuit. Once the circuit is disconnected, it will stay off until the fault has been cleared and the circuit has been reset.LEG1-1-63-15.0-A-01-V circuit breakers are used in various industrial and commercial facilities, such as power plants, production lines, factories and office buildings. They are also used in homes to protect circuits from overloading or short-circuiting, preventing damage to the circuits and people.In conclusion, the LEG1-1-63-15.0-A-01-V is an effective and reliable circuit breaker which is used to protect circuits from overloading or short-circuiting. It is made up of several components which work together to detect and disconnect a circuit when an excess of current is detected. This type of circuit breaker is ideal for applications where high-voltage and high current are needed and is used in many industrial and commercial facilities.
