Circuit breakers are designed to interrupt an electric circuit as a safety meter and device in order to prevent damages due to overload failure and short-circuiting. They are used in both domestic and industrial settings to secure a variety of systems from overloading and short-circuiting. The LELHPB11-39249-120-V circuit breaker is a type of circuit breaker that provides a kA rating of 80 and a voltage rating of 120/240V. It is designed to be used in both residential and commercial applications, and it is certified to UL 489 Standard.

The working principle of LELHPB11-39249-120-V circuit breaker is based on the thermal-magnetic principle. It features thermal-magnetic trip units that detect current overload and short-circuit conditions. That means that it uses a combination of heat generated by the current passing through the breaker and the cylindrical magnetic field around the breaker as a tripping mechanism.

When current overloads, the heat increases in the breaker so the breaking point is reached. This will cause the breaker to open quickly to disconnect the circuit and prevent the system from being damaged. This is referred to as thermal tripping. On the other hand, when short-circuits occur, the cylindrical magnetic field created by the current produces an opposite force that causes the breaker to trip. This is referred to as magnetic tripping.

LELHPB11-39249-120-V circuit breaker can be used in a wide range of applications, such as residential heating systems, industrial production lines, and commercial buildings. It can be used to provide overload and short-circuit protection for protection of electrical systems from any dangerous or damaging current fluctuations. It is also suitable for protection against fires caused by short-circuits or current overloads.

In addition, LELHPB11-39249-120-V circuit breaker is designed to be self-reset after each interruption. This means that the breaker can be switched back on after power is restored. This eliminates the need to manually reset the breaker after each overload or short-circuit interruption. This self-resetting feature adds to the safety and convenience of using the breaker.

The LELHPB11-39249-120-V circuit breaker is an effective and reliable safety device for a variety of applications. Its combination of thermal and magnetic tripping mechanisms makes it ideal for protecting systems from overload and short-circuit conditions. Its self-resetting feature also makes it a convenient safety technology for homes and businesses. With its kA rating of 80 and voltage rating of 120/240 volts, it is suitable for both residential and commercial applications.
