The DZ47 series new miniature circuit breaker is suitable for overload and short circuit protection of lines, lighting, and power equipment in circuits with AC 50Hz, rated voltage of 230/400V, and rated current up to 100A and below. It can also be used for infrequent switching of lines and equipment under normal conditions.
The product complies with IEC60898-1 and GB/T 0963.1 standards.
The miniature circuit breakers in this set are made up of plastic housing, overcurrent protection, operating mechanism, contacts, and arc extinguishing system. The housing is constructed from durable and flame-retardant plastic material. The multi-pole circuit breaker is created by combining several single poles, with the protection and handle connected through rods and covers to maintain uniformity in the operation of each pole.
