Circuit breakers are electromechanical devices used to protect electrical circuits from sudden power surges or other forms of damage. They are designed to momentarily disconnect excess current from the circuit, and then re-establish contact with the circuit in order to restore power. The LMLC1-1RLS4-29949-40 circuit breaker is a single-pole type that is designed for use in low-voltage, low-power electrical applications.

Design Features

The LMLC1-1RLS4-29949-40 circuit breaker has a number of design features that make it well-suited for use in low-voltage, low-power applications. The device features a toggle switch that allows for easy operation and resetting. The switch also features an indicator light to let the user know when the circuit breaker has tripped. The device also has an adjustable trip current rating, allowing the user to adjust the amount of current that the breaker can handle before tripping. This can be done with the use of a screwdriver, making it easy to adjust without the need for specialized tools. Finally, the device is rated for both AC and DC currents, making it suitable for a wide variety of applications.

Working Principle

The LMLC1-1RLs4-29949-40 circuit breaker is a thermal-magnetic type device. This means that it uses both a heating element and a magnetic field to detect and react to excess current in a circuit. The device consists of two main components: a thermostat and a trip coil. The thermostat senses the temperature inside the breaker and triggers the trip coil when the temperature gets too high. The trip coil then generates a magnetic field that is used to cut off the power to the circuit. Once the temperature drops, the magnetic field dissipates and the breaker will be able to re-energize the circuit.

Applications & Limitations

The LMLC1-1RLS4-29949-40 circuit breaker is typically used in low-voltage, low-power applications such as domestic appliances and lighting systems. It is capable of handling AC and DC currents with a maximum voltage rating of up to 250V. The device may also be used in motor circuits with a maximum current rating of up to 10A. However, its adjustable trip current rating means that it may not be suitable for circuits with higher current ratings.

Conclusion

The LMLC1-1RLS4-29949-40 circuit breaker is a single-pole device designed for use in low-voltage, low-power electrical applications. It features an adjustable trip current rating, an indicator light to let the user know when the circuit breaker has tripped, and is rated for both AC and DC currents. The device is typically used in domestic appliance and lighting circuits, as well as motor circuits with a maximum current rating of up to 10A.
