LMLB1-1RLS4-36441-15-V

The LMLB1-1RLS4-36441-15-V is a type of circuit breaker.
A circuit breaker is an electrical switching device used to protect electrical systems from short circuits and overloads. Circuit breakers are housed within a switchgear cabinet and are connected to circuits via busbar systems or integrated into fixed or plug-in type air-insulated switchgear systems. The circuit breaker functions in similar ways to traditional fuses, but with far higher levels of reliability and safety.

Application Field

The LMLB1-1RLS4-36441-15-V is suitable for a variety of applications. It is mainly used in locations with high vibration or remote operated control. The circuit breaker is suitable for multiple pole mains and motor circuit applications. These include load break switch applications, heavy-duty motor control centers, and low and medium voltage switchgear, such as transfer switches, breaker-contactors, and general-purpose industrial line ups.

Working Principle

The working principle of the LMLB1-1RLS4-36441-15-V circuit breaker consists of two main components: a contactor and a trip unit. The contactor connects and disconnects the circuit, while the trip unit senses anomalous electrical current within the circuit and trips the contactor, breaking the circuit in order to protect the equipment from the anomaly. The trip unit operates by using the difference between the current applied to the circuit and the actual current passing through the system.

The circuit breaker\'s trip unit has two main mechanisms: an electromagnetic mechanism and a hydraulic mechanism. The electromagnetic mechanism operates when a significant difference is sensed between the current applied to the circuit and the actual current passing through the circuit. The hydraulic mechanism operates when a significant increase in current is either applied to the circuit or when a short circuit occurs and the trip unit senses the power surge. In either of the two cases, the circuit breaker trips the contactor and a spring pulls the contact apart, which immediately breaks the circuit.

Conclusion

The LMLB1-1RLS4-36441-15-V is a type of circuit breaker that is designed to provide protection to electrical systems from short circuits and overloads. The circuit breaker is mainly used in locations with high vibration or remote operated control and is suitable for a variety of applications, such as load break switch applications and heavy-duty motor control centers. Its working principle consists of a contactor and a trip unit, which operate by using the difference between the current applied to the circuit and the actual current passing through the system. Ultimately, the circuit breaker is an essential piece of equipment in providing protection to electrical systems from potential danger.
