The Mikro X20 Earth Fault Relay is a compact, reliable solution for detecting earth faults in electrical systems. It offers both definite-time and selectable IDMT curve protection, ensuring accurate fault detection and easy coordination. With dual setting groups, users can quickly switch configurations for different operating conditions. The X20 features event logging with timestamps for fast, accurate fault analysis and RS‑485 Modbus-RTU for seamless integration with SCADA or monitoring systems. Built-in harmonic blocking and inrush detection reduce nuisance tripping, ensuring stable operation. Compliant with IEC 60255 standards and designed for easy installation, the X20 delivers advanced protection in a user-friendly, cost-effective package.
The X20 offers both definite-time and user-selectable IDMT curves, allowing precise coordination with downstream protection devices for enhanced system reliability.
Switch between two independent setting groups with ease, enabling quick adaptation to varying load conditions, maintenance scenarios, or system upgrades without reprogramming.
The X20 keeps a detailed, time-stamped record of faults and trip events, ensuring rapid, accurate fault diagnosis and simplifying maintenance and system analysis.
Built-in RS‑485 Modbus‑RTU communication allows effortless integration with SCADA, Building Management Systems (BMS), and other remote monitoring setups for complete system visibility.
With harmonic blocking and inrush current detection, the X20 eliminates nuisance tripping, ensuring stable protection even in environments with fluctuating loads or starting currents.
