Circuit breakers are designed to provide an electrical circuit with protection against overvoltage and overload current by disconnecting and breaking the circuit electricity flow. The LMLB1-1RLS4-38040-1 circuit breaker is used in AC 50/60 Hz low-voltage applications for the protection of installations in both residential or commercial and industrial or utility environments.

Overview

The LMLB1-1RLS4-38040-1 circuit breaker is an electromechanical device which uses a current sensing coil, enclosure and circuit contacts to detect and disconnect an overload or overvoltage in an electrical circuit. It is capable of breaking a large current (at least twenty-five times the rated current) with a high speed, in less than three milliseconds. The device is also connected until the fault is corrected and the circuit restored, at which time the resetting is instantaneous.

Operating Principle

When a large current is detected in the circuit, the sensor coil or element in the device heats up and expands, thereby moving the contacts apart. This interrupts the flow of electricity in the circuit and the breaker trips, effectively breaking the circuit. It is possible to reset the device manually by pushing its button or handle, or it can be reset automatically if the current returns to safe levels. In order to protect it from overheating, the LMLB1-1RLS4-38040-1 circuit breaker is equipped with a thermal overload switch.

Application field

The LMLB1-1RLS4-38040-1 circuit breaker is used in a range of applications including domestic heating, industrial and utility environments, solar and photovoltaic systems, HVAC systems, electric vehicle charging stations, lighting and other automated control systems. The device can be used in environments with ambient temperatures from -25°C to +60°C as it is rated for up to 24 kA/400-415V AC.

Advantages

The LMLB1-1RLS4-38040-1 circuit breaker offers a number of advantages over traditional circuit breakers. It is more energy efficient due to its quick response time and the use of a thermal overload switch. Additionally, its design is highly reliable, which leads to minimal downtime and a prolonged lifespan. Its small size also makes it ideal for applications where space is limited.

Conclusion

The LMLB1-1RLS4-38040-1 circuit breaker offers a reliable, cost-effective and energy-efficient protection against overvoltage and overload current. The device can be used in a range of applications in both residential and industrial environments, and offers a long service life and minimal maintenance. It is an ideal safety solution for many electrical load configurations.
