Circuit Breakers are a vital component in the electrical world, and are an integral part of any electrical system. LEJ66-1-63-20.0-FZ-01-T is one such circuit breaker, which is a low voltage molded case circuit breaker (MCCB). It is a two-pole breaker, meaning that it disconnects the circuit at both poles with a single operation. This circuit breaker is rated for up to 2000A, and is used in applications where both current and voltage are at a relatively low level, typically up to 600V.

The purpose of a circuit breaker is to protect both the equipment and the users of the electrical system from short circuits, or any other unexpected or dangerous fluctuations in current. To do this, the breaker interrupts the current quickly and safely when the current reaches a predetermined level. Circuit breakers come in many different types, each designed for different applications and different levels of current. LEJ66-1-63-1-20.0-FZ-01-T is specifically designed for low voltage applications, and is suitable for use in low current circuits such as lighting systems, heating systems, and motor circuits.

The working principle behind the LEJ66-1-63-20.0-FZ-01-T circuit breaker is relatively simple. The breaker consists of a magnetic actuator, a thermal overload protection device, and a set of contact arms. When the current in the circuit exceeds the preset level, the magnetic actuator quickly moves the contact arms away from each other, disrupting the circuit and preventing an overload. The thermal protection device prevents the circuit breaker from over-heating, ensuring that it functions correctly and effectively.

One of the main advantages of using the LEJ66-1-63-20.0-FZ-01-T circuit breaker is that it is able to handle large currents up to 2000A, while still maintaining a very low voltage. This makes it a cost-effective solution for applications such as lighting systems, heating systems, and motor circuits which all require low voltage but high current. The breaker also has the ability to detect ground faults, which can help to provide an added level of safety in hazardous environments.

In conclusion, the LEJ66-1-63-20.0-FZ-01-T is a low voltage moulded case circuit breaker that is designed for applications where both current and voltage are at a relatively low level. The breaker is capable of handling large currents up to 2000A, while still maintaining a very low voltage, and is able to detect ground faults for added safety. This makes it an ideal solution for applications such as lighting systems, heating systems, and motor circuits.
