Sensitive 5A Earth Fault Protection Relay for Earth Leakage Protection

A relay used in the power system to detect neutral or ground faults measure the vector difference of the three phase power, or measure the neutral current directly.


KRIPALRelay is a micro-mrocessor based electronic protection device designed to recognize current leakage to ensure the protection of electrical installations and persons against direct and indirect contacts.

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, IDMT characteristic curves which provide multiple matching protection characteristics curve for different load types.
