The MK2200L is a multifunction numerical relay designed for reliable overcurrent and earth fault protection in three-phase electrical systems. It offers three-stage settings for phase overcurrent, two-stage settings for earth fault detection, thermal overload protection, trip circuit supervision, and circuit breaker failure protection. It also supports the MODBUS-RTU protocol for seamless integration into monitoring systems. The relay records up to 50 fault records, 250 event records, and 30 alarm records with timestamps, providing comprehensive fault analysis and system diagnostics. Programmable digital inputs and outputs allow customization to suit various operational requirements. Its compliance with the IEC 60255 standard ensures quality and compatibility with other protection devices. The MK2200L is an essential tool for modern power management applications, offering reliability and versatility.
