LEJBX11-1-62-20.0-AG-N3-T – Circuit Breakers

Application Field

LEJBX11-1-62-20.0-AG-N3-T is a type of circuit breaker designed for low voltage (<1000V) applications. The device can be used for residential and commercial buildings, substations, office buildings, and factories. It is capable of handling current up to 20A and is compatible with both AC and DC systems. The device is often used in applications where safety is a priority, such as those where an arc flash is likely to occur. The device is designed to break the circuit and prevent arcing or arc flashes, which can cause serious damage and injury.The device comes with a variety of features, depending on the type. These features can include a manual trip switch, a current limiter, an overcurrent protection device, and a form that can be modified to determine the current and voltage ratings of the device.

Working Principle

The working principle of LEJBX11-1-62-20.0-AG-N3-T circuit breaker is relatively straightforward. In a closed circuit, it allows the current to flow freely. But when it detects an overload, either instantaneous or sustained, it will trip, breaking the circuit and preventing current from flowing. The device is composed of three internal components: a thermal element, an electromagnetic element, and a mechanical element. When current is detected to be higher than the rated level, the thermal element will start to heat up. When the heat reaches a specified level, it will activate the magnetic element, which in turn will activate the spring-loaded mechanical element. When the mechanical element is activated, it will trigger the circuit breaker to trip, and the current will be cut off. The circuit breaker will then reset itself when it has cooled off. This is done by a reset lever on the device that the user must manually activate.

Safety Features

The device has a number of features that ensure safety. The amount of current that it can handle before tripping is precisely calculated, and cannot be adjusted by the user. Additionally, the device has a form that can be modified to determine the current ratings, and overcurrent protection devices to ensure that the circuit is not overloaded. The device also has a manual trip switch, which can be used to shut off the current in an emergency. This is useful for emergency situations, such as a fire, when access to the breaker box might be difficult. Finally, the device has an arc flash protection feature, which is important for areas prone to arcing and arc flashes.

Conclusion

LEJBX11-1-62-20.0-AG-N3-T circuit breaker is a type of device designed for low voltage applications. It is capable of handling up to 20A of current and is compatible with both AC and DC systems. It has a variety of features ensuring safety, including a current limiter, an overcurrent protection device, and an arc flash protection feature. The working principle of the device is relatively straightforward and is composed of three internal components. The device is ideal for use in areas where safety is a priority, such as applications involving an arc flash.
