Precise Earth Fault Detection

The CSPC MRI1-I1-R1-S1-R1-HD relay continuously monitors residual current in the circuit, ensuring quick response to earth leakage or fault conditions. Its adjustable sensitivity from 30mA to 3A makes it suitable for diverse electrical environments, providing reliable protection to people and equipment. The device identifies faults rapidly, prompting fast isolation of defective circuits and minimizing potential hazards.


User-friendly Operation and Mounting

Designed with end users and installers in mind, the relay features a simple DIN 35mm rail mounting, meeting EN 60715 standards. Installation and wiring are straightforward with screw-type terminals supporting up to 2.5mm2 cable. The clear LED indicator, selectable manual or auto reset functions, and compact dimensions make integration and operation easy, saving time during maintenance.


Robust Build and Reliable Performance

Engineered for durability, this earth fault relay boasts high insulation resistance (>100M at 500V DC), strong dielectric strength, and mechanical life above 1 million operations. Its IP20/IP40 protection ratings ensure safety and resilience, while compliance with IS/IEC 60255-1 assures performance under stringent operational conditions. The relay operates optimally across a wide temperature range, with low power consumption for energy efficiency.
