Circuit Breakers have been a staple of electrical systems throughout the world for decades now and their importance to our electrical infrastructure simply can not be overstated. The LEGSF66-35199-30-V circuit breaker is one such model of breaker, and this article will cover its application field, as well as its working principle.

Application Field

The LEGSF66-35199-30-V circuit breaker is a 3-pole device designed and rated for 600 volts AC and 10,000 ampere interrupting capacity. This makes it the ideal circuit breaker for use in the heavy duty and medium voltage industrial market, including power distribution and control panels, industrial and marine applications, and other such settings. Its ratings are suitable for both one-line and three-line functioning, making it equally applicable for both applications.

However, its application is not limited to just electrical settings. The LEGSF66-35199-30-V circuit breaker has also been designed and tested to withstand the most adverse operating and environmental conditions, allowing it to find more niche applications in environments like mining, underground explosions, and other hazardous conditions.

Working Principle

The LEGSF66-35199-30-V circuit breaker works by controlling, monitoring, and protecting electrical circuits against overloads and short-circuits, as well as providing a means of opening and closing the circuit in order to de-energize any part of an electrical system. Its operation is dependent on several key components, including the terminal, trip shaft, and adjusting current interface.

At its most basic, the trip shaft is responsible for the switching mechanism of a circuit breaker. It consists of a reset arm, which also operates as a switch, and the connecting bus. When the trip arm is tripped, the reset arm snaps shut, and the circuit breaker is opened. The reset arm is then locked in position, allowing the circuit breaker to remain open until it is manually reset.

The LEGSF66-35199-30-V circuit breaker is equipped with an adjustable current interface, which is what allows the device to respond to different levels of current running through the system. This means that the device will only trip in the case of an overload or short circuit, and not just when the current flow changes.

The LEGSF66-35199-30-V also has an advanced protection system that makes use of a number of different components to monitor the system for any fluctuations in the current. These components monitor for any increases or decreases in current going through the system, and if any are detected, the circuit breaker will automatically switch off the circuit, preventing any further damage from occurring.

Conclusion

The LEGSF66-35199-30-V circuit breaker is a versatile and reliable device designed to provide optimal protection against overloads and short-circuits in various electric systems, ranging from power distribution and control panels to hazardous environments. Its durable construction, adjustable current interface, and advanced protection make it a reliable choice for any application.
