Circuit breakers protect factories, homes, and businesses from the dangerous effects of electric shocks and overloads. The LEGBX66-37021-1-V circuit breaker is an example of one such device, designed to protect electrical systems from unexpected overloads. This article will explore the application field and working principle of the LEGBX66-37021-1-V circuit breaker.The LEGBX66-37021-1-V is a type of thermal-magnetic circuit breaker. It is a double-pole circuit breaker, meaning it has two sets of terminals, allowing two separate circuits to be protected. The breaker is also both bolted, which is when it deviates from ambient temperature, and manually adjustable, which means the user can manually adjust the trip current setting.As far as applications are concerned, the LEGBX66-37021-1-V circuit breaker is ideal for a wide range of industrial applications. It is commonly used in commercial and industrial environments for protecting HV and LV power supplies, motor drives, distribution boards, and variable speed drives.The way in which the LEGBX66-37021-1-V circuit breaker works can be broken down into two different mechanisms: thermal protection and magnetic protection. The thermal protection mechanism works by detecting an increase in temperature within the circuit breaker and tripping the circuit in order to prevent the system from overloading. The magnetic protection mechanism works in a similar way, by detecting an increase in current and tripping the circuit in order to prevent the system from overloading.When the LEGBX66-37021-1-V circuit breaker is in normal operation, current is allowed to flow freely through the device. When the current reaches a certain level, the breaker trips, cutting off the power supply to the circuit and protecting it from potential damaged caused by an overload. The circuit breaker will remain in the tripped state until manually reset by the user.The trip current settable range for the LEGBX66-37021-1-V is from 4A to 100A. The adjustable factory setting range is from the trip current down to 0.25 times the trip current. The current rating for the breaker is 100A, with a voltage rating of 690VAC, with a frequency of 50/60Hz.The LEGBX66-37021-1-V circuit breaker is designed to be extremely reliable in operation, designed and tested according to the requirements of IEC 60947-2 and EN 60898. It is encased in a robust enclosure to ensure protection against dust, moisture, and interference.In conclusion, the LEGBX66-37021-1-V circuit breaker is a reliable and efficient device designed to protect electrical systems from possible overloads. It is ideal for commercial and industrial applications and is rated for up to 100A with a voltage rating of 690VAC. The breaker is also adjustable and able to detect both thermal and magnetic increases in current in order to trip the circuit and protect it from potential damage.
