Circuit breakers are essential components of any electrical system. They are designed to protect the circuit from overloading or short-circuiting, and when the load exceeds the breaker’s capacity, it will trip and cut off the current from the circuit. The LELBXKM11-40733-20-V is one such type of circuit breaker, and this article will discuss its application field and working principle.

This particular circuit breaker is a three-phase low voltage circuit breaker rated for 231A at 480VAC/500VDC. It is designed to protect motors and equipment from overloads and short circuits by sensing the load and breaking the circuit when the load is too high. The breaker is rated to carry 35,000A interrupting current at 480V AC. It is suitable for use in a variety of applications, from factories and shops to motor circuits and control circuits.

The LELBXKM11-40733-20-V has two distinct working principles. The first is the thermal-magnetic working principle, which uses a combination of a thermal element and a magnetic element to trip the circuit breaker. The thermal element is designed to detect an overload in the circuit, while the magnetic element is designed to detect a short circuit. When either of these elements detect an overload or a short circuit, they will trip the circuit breaker and cut off the current.

The second working principle is the electronic trip working principle. This works by using a DC voltage and an electronic trip unit to detect an overload. The electronic trip unit will detect an overload and break the circuit, protecting the circuit from further damage. This working principle is used in circuits that require a high level of precision or extended protection from overloads.

In addition to its application field and working principles, LELBXKM11-40733-20-V also includes other features such as electronic trip indication and current limitation. This feature is used to limit the amount of current that can pass through the breaker, preventing damage to the circuit. This circuit breaker is also equipped with a locking mechanism that prevents the breaker from being manually reset.

The LELBXKM11-40733-20-V circuit breaker is a versatile and reliable component for any electrical system. It is designed to protect circuits from overloads and short circuits, keeping circuits safe and functioning properly. As it is suitable for use in a variety of applications, it is a great choice for any circuit protection needs. Its two working principles, thermal-magnetic and electronic trip, provide additional protection and flexibility. And its features, such as current limitation and locking mechanisms, add even more protection to any circuit.
