English Introduction

The JL30 series integrated circuit current relay is a high-performance electrical protection device widely used in power systems, industrial automation control, and current monitoring and protection of various electrical equipment. Based on advanced integrated circuit technology, it has precise current detection capabilities and can monitor the current in the circuit in real-time and stably. When the current value exceeds the set threshold, the relay can respond quickly and cut off the circuit in time, effectively avoiding equipment damage and fire safety accidents caused by overcurrent, providing reliable protection for the safe operation of electrical systems.

Its internal structure is compactly designed with high-quality electronic components to ensure the stability and durability of the product. It has good anti-interference ability and can still work stably in complex electromagnetic environments without being affected by external electromagnetic signals, ensuring the accuracy of current detection. At the same time, the relay is easy to operate. Users can flexibly set the current threshold according to actual needs, which can be easily achieved through simple dip switches or adjustable potentiometers, without the need for a complex commissioning process, making it convenient for users to quickly put it into use. In addition, it has a small volume and light weight, making it easy to install in various space-limited locations and can be easily integrated into various electrical control systems to meet the application needs of different users.
