LEGBXF66-40420-20-V Circuit Protection

Circuit breakers are an integral part of industrial automation and electric safety systems, protecting machines, people, and components from electric shock and overload. The LEGBXF66-40420-20-V circuit breaker is a reliable, cost-effective, and compact solution to a variety of electric problems.

The LEGBXF66-40420-20-V is an extremely versatile circuit breaker. Its broad range of applications includes protection against overloads and short circuits in low and medium-voltage circuit breakers, over-current protection for lighting circuits, and motor control in HVAC systems. The circuit breaker is designed for single pole, 2-pole, and 3-pole applications, making it a reliable and effective solution for a variety of electric problems.

The LEGBXF66-40420-20-V circuit breaker is composed of a number of components that each provide a specific function. The breaker body is made from UL rated Gould polyester, providing a flame-retardant and highly-durable solution to internal electric protection. A contact actuation spring, normally open, is installed to ensure reliable contact closure when needed. The circuit breaker features adjustable trip settings and thermal overload protection, further ensuring safety and efficient operation.

The LEGBXF66-40420-20-V\'s working principle is simple. When the circuit breaker is closed and the circuit is carrying current, an electromagnet within the breaker activates the trip mechanism. When the current in the circuit exceeds a certain limit set by the adjustable trip settings, the overload indicator in the trip mechanism is activated and the breaker trips, breaking the circuit and preventing further electric current from passing through. Once the overload is resolved, the breaker can be reset to allow the flow of current through the circuit. This reset can either be automated or manual, depending on the user\'s preference.

The LEGBXF66-40420-20-V circuit breaker is a reliable, cost-effective, and compact solution to many of the electric problems found in industrial automation and residential electricity. It is easy to install and use, and provides the necessary safety to ensure that both people and equipment are protected. With adjustable trip settings, thermal overload protection, and durable construction, the LEGBXF66-40420-20-V is a great choice for any electric protection needs.
