Mikro’s cost-effective earth fault relays comprehensively detect and activate trip protection to medium and low voltage applications. The series of earth fault relays are microprocessor-based numerical relays and are housed in resilient mounted casing. The high end model, MK232A includes five selectable IDMT characteristic curves which provide multiple matching protection characteristics curve for different load types.
- Accurate, reliable and more resistant to vibration and shock than traditional electromechanical relays
- Current measurement based on fundamental frequency, prevents nuisance tripping
- Programmable relay outputs
- Complies with IEC 60255-26 standards
