The X60 Combined Overcurrent & Earth Fault Relay from Mikro is engineered to directly address the shortcomings of conventional protection systems by delivering a precise, intelligent, and integrated fault protection solution for modern electrical networks.
To tackle the challenge of delayed fault isolation and limited system visibility, the X60 incorporates numerical protection technology with three-phase, multi-stage protection (three stages for overcurrent and two for earth fault). These programmable settings allow engineers to fine-tune protection curves—including IDMT and definite-time characteristics—ensuring rapid and selective fault clearing without compromising system coordination.
The X60 enhances operational reliability through features such as trip circuit supervision and breaker failure detection (ANSI 74TC & 50BF), preventing false operations and ensuring circuit breakers function as intended. The inclusion of thermal overload protection (49RMS) safeguards equipment from prolonged overcurrent stresses, extending asset life and preventing costly downtime.
Addressing the need for system intelligence and remote diagnostics, the X60 supports RS232/RS485 MODBUS-RTU communication, allowing seamless integration with SCADA and energy management systems. Through the Mikrosafe software interface, users can remotely monitor system parameters, review event and fault logs, and adjust settings, improving transparency and supporting predictive maintenance strategies.
Its compact form factor and programmable digital I/O make it ideal for retrofitting existing panels or deploying in space-constrained environments, reducing both installation time and cost. Compliant with IEC 60255, the X60 ensures reliable operation under demanding industrial and utility conditions.
By combining protection, monitoring, and communication into a single, intelligent unit, the X60 not only enhances system safety and reliability, but also empowers operators to achieve greater efficiency and smarter fault management in today’s evolving electrical infrastructure.
