Earth-fault relay is used to protect feeder against faults involving ground . when the relay feel the earth leakage cut main current and prevent electric shock . Wide applications of single phase and three phase power and industrial systems , and almost 80% of the electrical power command circuits are used in factories and other places. Bornika is the exclusive representative of Contrel company, in purchasing , sales, consulting and distribution of industrial equipment including Earth Leakage and Earth Fault Protection Relay.

  • The ELRC-1 have the particularity that they are manufactured with the buit-in Toroidal Transformers . They are specially conceived for those applications , in which the space saving is an advantage (for example, in MOTOR CONTROL CENTERS, BATTERIES OF DISTRIBUTION, etc.) . Although its reduced dimensions , the relay has as wide setting ranges as the other ELR's series . Other important feature is its insensitivity to external disturbances and pulse currents with dc components (presents in the line), due to the filters built on the input circuits .
