This series of relays can be combined with low-voltage circuit breakers or low-voltage contactors to form a combined residual current operated protective device. It is mainly suitable for TT or TN system distribution lines with AC 50Hz and rated voltage of 400V and below, preventing equipment and electrical fire accidents caused by ground fault currents, and can also provide indirect contact protection against electric shock hazards to persons.
Applications
Applications requiring residual current detection and ground fault protection of electrical lines.
