Circuit Breakers: LELBX1-1-63-30.0-M3-V Application Field and Working Principle

Circuit breakers are essential devices in industrial electrical engineering and circuit protection devices used in machine building and other branches of industry. Based on the definition, circuit breakers are safety switches used mainly in AC circuits, which can cut off the circuit, prevent the current load from burning the underlying cable and ensure the safe isolation of the power train in the system. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to the load voltage level. The LELBX1-1-63-30.0-M3-V circuit breaker is a low-voltage breaker (<1000V) and belong to the low-voltage circuit breaker product family.

The application field of the LELBX1-1-63-30.0-M3-V circuit breaker is in the field of protection. With a rated voltage of 630V and a rated short-circuit withstand current of 30.0kA, it can be used to protect cables in various industrial production fields. It is suitable for usage in AC 50Hz and DC system with a rated working voltage of not more than 380V (16A, 20A) and 240/415V (32A, 41A). It can also be used as a disconnecting switch, emergency switch, and flow switch, to ensure the safety operation of electrical equipment.

The working principle of the LELBX1-1-63-30.0-M3-V circuit breaker is based on the principle of the magnetic circuit and the electrical operation, in which a pair of contacts, the main contact and the auxiliary contact, are connected in series in the control circuit, and the electromagnetic release and the operating mechanism of the handle control the opening or closing of the main contact. When current passes through the circuit breaker, a magnetic field is generated, which is proportional to the size of the current. When the current exceeds the rated operating current, the motor controlled current in the circuit breaker electromagnetically intervenes, drives the operating mechanism, and realizes the separation between the main contacts and the auxiliary contacts, thus cutting off the power supply in the circuit and protecting the circuit. At the same time, the circuit breaker can also achieve short-circuit protection, overload protection, and voltage protection.

In addition, the properties of the LELBX1-1-63-30.0-M3-V are also noteworthy. It features a unique quick-break function and has a capacity of breaking large currents within a very short period of time without risk of damage to its internal structure. This has made it ideal for use in cases that require rapid disconnection of power such as medical equipment and other similar high-precision electrical devices. It also has an anti-inverting function, which can reduce the effects of circuit overload by providing an overload shutdown capability that reverses the effects of an over-current. Furthermore, its insulation resistance is up to 10KV, providing strong protection against shocks and fires.

Due to its unique features, the LELBX1-1-63-30.0-M3-V circuit breaker is widely used in many industrial production fields and home applications, to ensure the safety operation of the electrical equipments and circuit protection devices. The combination of the quick-break action and the anti-inverting capability makes it an extremely important safety device in almost any electrical situation. Whether it is a home electrical system or an industrial application, the LELBX1-1-63-30.0-M3-V circuit breaker can provide an effective and reliable solution.
