Circuit Breakers are used for electrical circuit protection. The LEGBX66-36752-20-V is a type of circuit breaker that is used to help prevent overcurrents and overvoltages caused by faults or surges in an electrical circuit. The LEGBX66-36752-20-V is also capable of providing overcurrent and overload protection, as well as short circuit protection.

Specifically, the LEGBX66-36752-20-V is a Trip Curve C circuit breaker. This type of breaker is designed to provide protection against both overloads and short circuits, and is classed as a Type 2 circuit breaker. This means that it is suitable for protection of motor loads, and can provide both short circuit and overload protection for motors up to 75A.

The LEGBX66-36752-20-V circuit breaker is designed for use in various kinds of electrical equipment. It can be used in a variety of industrial, commercial, and residential applications, including HVAC systems, pumps, fans, and hoists. It can also be used in high efficiency equipment, such as lighting systems, temperature control systems, and solar installation systems.

The working principle of the LEGBX66-36752-20-V circuit breaker is relatively simple. It utilizes a thermal-magnetic technology, which means that it has a thermal element and a magnetic element. The thermal element senses any excessive flow of current and triggers the breaker, whereas the magnetic element protects the circuit when there is a sudden surge in the current. When either the thermal element or the magnetic element detects an overload, it triggers the breaker, which opens the circuit and prevents further damage to the equipment.

The thermal element works based on the Joule effect, which states that when current is applied to the element, it generates heat. This heat is sensed by the thermal element, and when the level of heat reaches a certain threshold, the signal is sent to the breaker, triggering the mechanism that will intervene and open the circuit.

The magnetic element works by sensing the difference between the current in a circuit when a surge or a fault occurs. When the current level rises above a certain set threshold, the magnetic field generated by the element will act against the current and will act to open the circuit.

The LEGBX66-36752-20-V circuit breaker is a reliable and effective way to protect electric circuits from damage caused by overcurrent or overvoltage, and is designed for use in a variety of industrial, commercial, and residential applications. It utilizes a combination of thermal-magnetic technology to detect overloads and short circuits, and is capable of providing protection for motors up to 75A.
