LEGBX66-35782-20-V Circuit Protection

Circuit breakers protect an electrical system from damage caused by overloads, short-circuits, or ground faults. The LEGBX66-35782-20-V is a reliable, safety-tested miniature circuit breaker that offers overload and short-circuit protection for commercial and industrial applications. This article will discuss the application field and working principle of the LEGBX66-35782-20-V.

Application field of the LEGBX66-35782-20-V

The LEGBX66-35782-20-V is a miniature circuit breaker that is suitable for a variety of residential and industrial applications. It is an ideal choice for use in circuits that have a large number of smaller loads. It is also suitable for situations where space is a limitation due to its miniature design. Some specific application fields where the LEGBX66-35782-20-V can be used include:

• Industrial machinery applications, such as pumps, fans, compressors and motors.
• Control circuits, including thermal overload relays, temperature and pressure controls, contactors, and motor starters.
• Household appliances, such as washers, dryers, dishwashers, refrigerator and freezers.
• Lighting fixtures and motor overload applications.

Working Principle of the LEGBX66-35782-20-V

The LEGBX66-35782-20-V is a thermal-magnetic breaker that works by using both a thermal mechanism and a magnetic mechanism to control the flow of electricity. The thermal mechanism works by increasing the temperature of the circuit breaker when a high current is detected. This increase in temperature is caused by the heat generated when a large current passes through the circuit breaker. When the temperature reaches a certain threshold, the thermal contacts open and the flow of current is interrupted. The magnetic mechanism works by increasing the magnetic field in the circuit breaker when it is exposed to a high current. The magnetic field creates a force on the circuit breaker contacts that interrupts the flow of electricity and trips the breaker. The LEGBX66-35782-20-V also has two indicators, one for normal operation, and one for when the breaker has been tripped by either the thermal or magnetic mechanism.

The LEGBX66-35782-20-V is an easy-to-install and reliable circuit breaker that provides overload and short-circuit protection for a variety of residential and industrial applications. It can be used in areas where space is a limitation due to its miniature size. Its thermal-magnetic mechanism is reliable, safety-tested, and will provide dependable protection of your electrical system.
