The LELHPK11-32570-1-V circuit breaker is a device designed to manually disrupt the electrical circuit or interrupt the fault current. It is often installed in places where direct current is used, such as in factories, households, laboratories and other industrial usage, due to its high tolerance to low current. It is a miniature direct current circuit breaker used as a direct current overprotecting device or short-circuit protective device.

The LELHPK11-32570-1-V employs a send iron-type split core configuration and uses an adjustable fuse with latching trip action combined with a thermal memory to provide a trip and reset. This breaker has a manual reset button which is used to reset the breaker after an interruption. It has a wide range of variable trip and reset settings to ensure the safety of the electrical system. It also has the ability to detect and prevent false tripping.

In terms of its application field, this device is mainly employed in equipment safety and pre-alarm control services, mainly in automatic control systems and communication devices, as its design allows it to detect electrical accidents quickly. Its small electric resistance allows it to work more stably and reliably. It has a broad applicability for medium and low voltage circuits with its adjustable and reliable protection.

As for its working principle, the LELHPK11-32570-1-V relies on the thermal characteristics of the current flowing through it. When the current is higher than its rated value, the heat produced by the current heating the fuse material will cause the fuse material to expand, thereby increasing the electric resistance, resulting in an increase in the temperature of the fuse material. When the temperature reaches a certain level, the breaker will be automatically tripped. After the current is reduced below the rated value, the fuse material will then cool down to its original temperature, and the breaker will reset automatically.

In conclusion, the LELHPK11-32570-1-V circuit breaker is suitable for low and medium-voltage applications because of its adjustable and reliable protection. It works based on the thermal characteristics of the current flowing through it and automatically trips and resets when it reaches certain levels. It is also capable of detecting and preventing false tripping, and is mainly used for equipment safety and pre-alarm control services.
