Circuit Breakers

LEGBX6-38940-20-V circuit breakers are designed for application in the most demanding environments, providing maximum safety and reliability. These robust, reliable and flexible circuit breakers give optimized protection to any equipment, even in demanding conditions. They provide precise protection, while also offering precise current sensing of high impedance, low impedance, and high-current loads.

Application Field

LEGBX6-38940-20-V circuit breakers are mainly used in industrial, commercial and residential environments. They are perfect for a wide range of applications, such as motor and generator protection, induction motor overload protection, phase unbalance protection, transformer over current protection, line protection, low voltage distribution and supply, surge protection and circuit protection. They are suitable for use at 600VAC and can be used in temperatures ranging from 0° to 40°C. Their performance is optimized at 40°C.

The circuit breakers are designed with overload current tripping characteristics which make them suitable for transformer over current protection in particular. The built-in surge protector offers the best protection for your valuable equipment. In addition, the LEGBX6-38940-20-V circuit breakers are designed with a built-in temperature compensation system, which automatically adjusts the tripping current to the changes in temperature.

Working Principle

The LEGBX6-38940-20-V circuit breakers are equipped with an overload tripping mechanism. This mechanism uses an electro-magnetic field to detect over current conditions. When an overload is detected, the breaker trips, disconnecting the load from the supply. This prevents the load from exceeding its rated value and damaging the device.

The circuit breaker also utilizes a thermal tripping device which is activated when the temperature rises above the specified trip level. The breaker is then opened, reducing the heat generated by the trip and preventing further damage. As the temperature drops again, the breaker is reset and the load is reconnected.

The surge protector on the LEGBX6-38940-20-V circuit breakers is designed to protect against sudden overloads. This ensures that the circuit breaker can handle sudden surges in current, preventing damage to equipment.

Conclusion

The LEGBX6-38940-20-V circuit breakers are designed for the most demanding environments, providing maximum safety and reliability. They are perfect for a wide range of applications and can be used in temperatures ranging from 0° to 40°C. The overload tripping mechanism and temperature compensation system ensure precision in the protection of the load, whilst the surge protector offers further protection for the delicate equipment.
