Circuit Breakers: QLB-053-11B3N-3BA Application Field and Working Principle

Circuit breakers are electrical devices designed to automatically cut off the flow of current in case of a short circuit, power overload or other hazardous conditions. Circuit breakers are designed to provide safe and efficient protection of electrical systems and circuits. The QLB-053-11B3N-3BA is a type of automatic electronic circuit breaker developed by SpeedSwitch Technologies. This breaker has multiple applications and has many advantages.

Application Field

The QLB-053-11B3N-3BA can be used in a wide variety of applications such as residential, commercial, industrial and healthcare applications. This circuit breaker is particularly suitable for application in high current, low-voltage electrical systems. It is also suitable for use in automobile and aircraft electrical systems, as well as in household electrical appliances. The breaker can also be used to protect secondary equipment such as windings, fuses and transformers. Moreover, this breaker is noted for its stability and resistance to short-circuits.

Working Principle

The main principle of QLB-053-11B3N-3BA is its overvoltage protection. When an overvoltage is detected, the breaker will cut off the circuit in order to protect the circuit from possible damage. The breaker is designed to protect specific areas of the electrical system where overvoltage is present. The breaker senses and reacts to overvoltage in a very short time, making it faster than traditional breakers.The operation of the breaker is based on the principle of undervoltage monitoring. When the current flow in any of the connected electrical system’s circuits is below the specified level, the breaker will automatically activate, cutting off the power supply. This breaker also features several other special protection settings, such as under-frequency protection and anti-island protection.

Features

Some of the features of the QLB-053-11B3N-3BA circuit breaker include a highly reliable switching performance, a high breaking capacity and a fast response time. The breaker is designed to offer maximum safety to the electrical system by preventing the occurrence of large electric arcs and directing small arcs away from hazardous areas. The breaker also features a low voltage drop of less than 40mV when in steady state. The breaker also has a wide frequency range of between zero and 200 Hz, which makes it suitable for high frequency applications.The QLB-053-11B3N-3BA is a reliable and efficient breaker that is suitable for a variety of applications. It is designed to offer safety and protection to electrical circuits and systems. Through its overvoltage protection feature and its ability to cut off the power supply in the event of a short circuit or an overload, the breaker ensures that users’ safety is not compromised.
