X30 Combined Overcurrent & Earth Fault Relay
MIKRO MSC BERHAD
STI202501334
The X30 Combined Overcurrent and Earth Fault Relay is a sophisticated numerical protection relay designed to deliver reliable and intelligent protection for electrical systems. Suitable for both three-phase three-wire and four-wire configurations, it consolidates multiple protection functions into a single, compact unit. This makes it an ideal solution for modern industrial, commercial, and utility power networks where space, efficiency, and performance are critical.
At its core, the X30 provides robust protection against phase overcurrent, earth faults, and thermal overloads. It features programmable inverse definite minimum time (IDMT) curves, including NI, VI, EI, and LTI, to suit various system requirements. Additional capabilities include trip circuit supervision, circuit breaker failure protection, and thermal overload monitoring. The relay also supports RS485 MODBUS-RTU communication, enabling seamless integration with SCADA systems and remote monitoring platforms.
The X30 is equipped with four programmable digital inputs and four output contacts, allowing flexible configuration for diverse applications. Its LCD interface offers intuitive navigation, while its event, fault, and alarm logging, up to 250 timestamped records, supports proactive diagnostics and maintenance. The device complies with international standards including IEC 60255 for protection relays, as well as IEC 61000-6-2 and IEC 61000-6-4 for electromagnetic compatibility, ensuring reliable performance even in electrically noisy environments.
Designed for electrical engineers, facility managers, and system integrators, the X30 serves as a dependable solution for safeguarding critical infrastructure. Its compact design, advanced protection features, and standards compliance make it a strong candidate for MySTI certification and a valuable asset in any high-demand power distribution setting.
