NM1New FunctionsLocking

NM1New FunctionsSpecial Release for Prepaid KWH MeterUsed with the IC card prepaid KWH meter.When there is no balance in the user’s ICcard, the release will break the MCCB to cutthe circuit, and prevent the breaker frommaking again, so that the user cannot use thepower.Only until the user has recharged the IC cardwith a certain amount, the breaker can makenormally again. So this release can savemuch more labor and work quantity.
