Under the normal condition, it can be used for line infrequent conversion. The breaker with current less than 1250A can be used in a network of AC 50Hz, voltage 380V to protect the motor from overload and short circuit. It may also be used for infrequent motor start under the normal condition.The product is in conformity with the standards IEC947-2 and GB14048.2-94.The breaker NA1 is mainly suited for distribution network of AC 50/60Hz,rated working current up to 6300A,rated voltage up to 690V to distribute electric power and protect the line and the equipment against the damage due to overload,short circuit ,under-voltage and single phase earthing in transformer`s neutral point TN distribution system.
