Circuit breakers are an important part of any electrical system. They are designed to protect circuits from potential danger caused by overloading and short-circuiting. In this article, we’ll take a look at the LELBXK1-34917-2-C circuit breaker and explain the application field and working principle.

What is the LELBXK1-34917-2-C Circuit Breaker?

The LELBXK1-34917-2-C Circuit Breaker is a 3-pole molded case circuit breaker with a rated current of 100 A. The breaker is designed to provide overload and short circuit protection in low voltage systems with a rated voltage of 660V AC. It features an external arc-quenching chamber and a latch mechanism. The internal circuit of the breaker can be configured to offer high interruption performance and protection against electrical hazards.

Application Field

The LELBXK1-34917-2-C circuit breaker is designed for use in industrial and commercial applications. It can be used in switchgear, motor control centers, and other low-voltage equipment.

This breaker can also be used as a replacement for other breakers with similar ratings, provided the installed wiring configuration is compatible. It is suitable for applications that require a rated current up to 100 A.

Working Principle

The LELBXK1-34917-2-C circuit breaker is designed with a thermal-magnetic tripping system. The thermal element is a bimetallic strip that bends when exposed to heat. When an overload or short circuit occurs, the increase in temperature causes the bimetallic strip to bend and trip the breaker.

The magnetic element is a moving iron that is attracted to a fixed core when a high current flows through the circuit. The force of the current causes the moving iron to move, which in turn trips the breaker. This mechanism provides fast tripping when high currents are detected.

To reset the breaker, the electricity supply to the circuit must be switched off. Then, the trip indicator needs to be reset and the breaker can be turned back on. This resetting process must be done manually, as the breaker does not have an automatic resetting mechanism.

Advantages

The LELBXK1-34917-2-C circuit breaker has several advantages. Firstly, it offers reliable protection against overload and short circuit. The breaker is UL certified and is designed to be used in hazardous locations. The external arc-quenching chamber provides excellent protection in the event of a fault and reduces the risk of damaging equipment. Finally, the breaker is designed for easy installation and can be configured to meet specific application requirements.

Conclusion

The LELBXK1-34917-2-C circuit breaker is a highly reliable and versatile breaker designed for use in low voltage systems. It is designed to provide overload and short circuit protection and its thermal-magnetic tripping system ensures fast tripping when high currents are detected. The breaker is UL certified and can be configured for a variety of applications. It is an excellent choice for industrial and commercial applications that require reliable protection against electrical hazards.
