Circuit Breakers are important components used in electrical systems to protect equipment from damage due to over-current. The LEJBX66-40404-15-T circuit breaker is a three-pole, air circuit breaker with a rated current of 400A and a rated short-circuit capacity of 15kA. It is designed to provide reliable protection in residential, commercial and industrial applications, such as schools, hospitals, supermarkets and factories.

This circuit breaker is based on the principle of over-current protection. It features a current transformer that senses when the current reaches a certain level and then a relay is activated which opens the circuit breaker. This operation interrupts the electrical circuit, stopping further damage from occurring.

The LEJBX66-40404-15-T circuit breaker is designed to offer reliable protection against short-circuits in the electrical system. It supports a short circuit rating of 15kA and can be used in both commercial and industrial applications. It offers adjustable sensitivity of 0.2-1.0A and can easily be adjusted to meet different requirements.

The unique design of the circuit breaker ensures that it meets the highest standards of safety and reliability. The mechanical structure of the circuit breaker consists of three poles, a bimetallic strip, an arc plate, and a stainless steel actuator. The arc plate has a special design which minimizes contact wear and ensures sustained overload protection.

The operation of the LEJBX66-40404-15-T circuit breaker is simple and reliable. When the short-circuit occurs, the current transformer senses the high current and triggers the relay. This action opens the circuit breaker and interrupts the circuit. The arc plate then quickly absorbs the generated arc energy, and the bimetallic strip reset the circuit breaker. This reset process is completed by the stainless steel actuator, which ensures reliable breaking of the circuit and prevents the circuit from re-closing.

The LEJBX66-40404-15-T circuit breaker is a reliable and efficient protection device that is suitable for a wide range of residential, commercial and industrial applications. It offers adjustable sensitivity which can be set to meet different needs and provides reliable protection against short-circuits. It is reliable, easy to use and is capable of providing sustained overload protection.
