Circuit Breakers

A circuit breaker is a device that allows a circuit to be opened and closed in order to prevent overloading, short-circuiting, or other dangerous electrical events. Circuit breakers are typically installed in the breaker box alongside fuses, providing a reliable alternative to fuse protection. The LMLB1-1RLS4-37307-2-V is a circuit breaker designed for household, commercial, and industrial uses. In this article, we\'ll take a look at its application field and working principle.

The Application Field

The LMLB1-1RLS4-37307-2-V circuit breaker is mainly used for household, commercial, and industrial applications. It is applicable to AC 50/60Hz, rated voltage up to 660V, rated current up to 100A, and cut-off current ranging from 5A to 100A. Because this circuit breaker is a miniature circuit breaker, it can be installed in a small space, is cost-effective, and is also highly reliable and durable.

The Working Principle

The working principle of the LMLB1-1RLS4-37307-2-V circuit breaker can be divided into two parts: the thermal trip and the magnetic trip. In the thermal response mode, the built-in bimetallic sheet can detect the overload current and rapidly change its shape. This shape-change causes a mechanical link to open the circuit and thereby protect against overload. In the magnetic response mode, a magnetic trigger will detect the short-circuit current and produce a magnetic field. This magnetic field will cause the circuit switching element to open the circuit and shut off the power. Both thermal and magnetic trips are extremely fast, allowing for positive tripping even during high surge current rises.

Additional Safety Features

This circuit breaker model also has a number of additional features that provide greater safety. An additional contact is present that provides an alarm signal in case of an overcurrent beyond the trip setting. There is also an additional switch that is used to disconnect the panel when the circuit breaker is not in use. This switch prevents excessive current from being conducted through the breaker when it is not being actively used. Finally, this model also comes with thermoplastic and thermoplastic-filled components that further improve the breaker’s performance in various working conditions.

Conclusion

The LMLB1-1RLS4-37307-2-V is a circuit breaker designed for household, commercial, and industrial uses. It is applicable to AC 50/60Hz, rated voltage up to 660V, rated current up to 100A, and cut-off current ranging from 5A to 100A, making it an ideal choice for a wide variety of applications. The LMLB1-1RLS4-37307-2-V circuit breaker is highly reliable and durable, and features both thermal and magnetic trip capabilities, as well as a number of additional features that provide greater safety.
