L6 Programmable Low Voltage Motor Protection and Measurement Controller

The L6 programmable low-voltage motor protection and measurement device is an intelligent motor protection and measurement device developed based on ARM microprocessor technology. Mainly providing comprehensive protection and control for low-voltage motors in various application scenarios, improving the utilization rate of load equipment such as motors, and extending their service life. The appearance design is novel and unique, the workmanship is exquisite and beautiful, and the performance is safe and reliable. Embedded installation, convenient and fast, with a reasonable appearance design, can be installed in a minimum of 1/4 drawer cabinet. Integrating protection, measurement, monitoring, control, statistics, and communication, it has extremely high cost-effectiveness and stable and reliable performance.

This product, together with contactors, soft starters, molded case circuit breakers, and frame circuit breakers, provides a complete set of specialized solutions for low-voltage AC motor circuits that integrate control, protection, detection, and bus communication. It replaces various additional components such as thermal relays, current transformers, instruments and selection switches, indicator lights, programmable controllers, and transmitters, and is an ideal choice for intelligent MCC and PC. The programmable feature of L6 is particularly suitable for situations where simple logic control is required for motor circuits, and can replace small PLCs to save equipment investment.
