Circuit Breakers

Circuit breakers are vital components of electrical systems that serve to protect wiring, apparatus, and personnel in the event of an overload or short-circuit. They are automatic switches that open the circuit to stop current flow when a fault is detected, and then reset when the fault is cleared. Modern circuit breakers have become the go to form of protection for many applications. One such example is the LEJ6-1–63-15.0-F-01-T.

Application Field

The LEJ6–1–63-15.0-F-01–T is a 6kA circuit breaker that was designed to be placed in a switchboard or panel board setup. It is generally used in places with low voltage AC power and has a rated voltage up to 400V AC. The switch is equipped with a unique, densely populated “ring-type” design, which enables it to fit in most electrical panel boards. The device is able to function in temperatures ranging from -25℃ to +60℃ and it can be used in areas of moisture and/or dust.

Working Principle

When current is applied to the circuit, the switch closes, allowing electricity to flow through the circuit. The current is then monitored by an internal monitoring system that senses an overload condition and quickly opens the switch, cutting off the electrical current. This action prevents short-circuiting and damage to the components and wiring. When the overload condition is relieved and the current level returns to normal, the circuit breaker automatically resets and closes again.

The LEJ6-1–63-15.0-F-01-T also has a trip-free feature which allows it to open the circuit regardless of whether it is “on” or “off” when an overload is detected. This feature provides extra safety against short-circuits and other faults.

Conclusion

The LEJ6–1–63-15.0-F-01-T is a reliable and versatile circuit breaker that is suitable for applications with low voltage AC power. The automatic switch is able to quickly detect a fault and safely open the circuit, protecting the wiring and personnel. Its unique design allows it to fit into most panel boards, and its trip-free feature adds another layer of safety to the system.
