LEGBX66-70007-1-V Circuit Protection

Circuit breakers are essential components in an electrical system. They are designed to protect electrical circuits from dangerous spikes or surges by automatically cutting off the supply of electricity to the circuit. The LEGBX66-70007-1-V is a type of circuit breaker commonly used in industrial, commercial and residential electrical systems, as it is capable of protecting circuits from overloads and short circuits. This article looks at the application field and working principle of the LEGBX66-70007-1-V.

Application Field

The LEGBX66-70007-1-V circuit breaker is designed for use in low voltage electrical systems and is particularly suited to industrial and commercial applications. It can be used to protect a variety of appliances or electrical equipment, such as motors, transformers and generators. It can also be used in residential homes to protect appliances and lighting fixtures. The circuit breaker has a rated capacity of up to 20A, meaning it is capable of protecting circuits with currents of up to 20A.

Working Principle

The LEGBX66-70007-1-V circuit breaker works on a thermal-magnetic principle. It monitors the current passing through the circuit, which causes the internal thermal element to heat up. When the temperature of the thermal element exceeds a certain (defined) threshold, the breaker will trip and open the circuit. This helps to protect the circuit from any potential overloads or short circuits, which could otherwise cause serious damage.

The LEGBX66-70007-1-V also has a magnetic element, which is activated when the current exceeds a certain threshold. This causes the breaker to trip and open the circuit, preventing any further overloading or short circuits from occurring. The magnetic trip element is typically set at a higher level than the thermal element, ensuring that dangerous spikes in current are dealt with quickly and efficiently.

Summary

The LEGBX66-70007-1-V circuit breaker is a type of circuit breaker designed for use in low voltage electrical systems. It is most commonly used in industrial, commercial and residential applications, as it is capable of protecting circuits from overloads and short circuits. The breaker works by monitoring the current passing through the circuit, with both thermal and magnetic elements being used to detect dangerous spikes in current. When the current exceeds a certain threshold, the breaker will trip and open the circuit, preventing any potential damage.
