Circuit Breakers

The LELZXK21-1REC5-37198-80 is a type of circuit breaker, which is designed to protect electrical circuits against overloads or short circuits.

Application Field

The LELZXK21-1REC5-37198-80 is designed for use as a residential circuit breaker or in commercial/industrial applications. It is suitable for use in electrical distribution systems up to 600V. It is also designed for protection against short circuits in residential electrical systems, as it is rated for a short circuit current of up to 200A.

The breaker is also suitable for use in motor control circuits. It can be used for starting, reversing, and controlling electric motors, thus providing protection against short circuit and overloads. It is rated for a motor dry load of up to 40A.

Working Principle

The LELZXK21-1REC5-37198-80 features a non-trip design. This means that it will only trip when the current exceeds the rated capacity, or if an overload or short circuit occurs. When the breaker trips, it opens the circuit, thus disconnecting the power supply.

The breaker has a thermal-magnetic trip unit, which combines both thermal and magnetic action to detect overloads. The thermal element responds to the heat generated by an overload, while the magnetic element responds to the current in the circuit. When the overload current exceeds the rating of the breaker, the trip unit will open the circuit.

In addition, the breaker also has a manual reset button. This reset button is used to reset the breaker after a fault. This reset button must be pushed in order to restore power to the circuit.

Conclusion

The LELZXK21-1REC5-37198-80 is a residential or commercial/industrial circuit breaker. It is designed to protect electrical circuits against short-circuits and overloads. It provides reliable protection, and it is simple and easy to install. It is suitable for a variety of applications, including motor control circuits.
