Product overview
• ZQPN series miniature circuit breakers are applicable to the lines with AC 50/60Hz, rated voltage 230V, rated current 6A to 32A to protect the overload and short circuit of electrical lines. The exterior of ZQPN is the same as the ordinary single-pole ZQNC circuit breaker, while the interior is designed with a two-pole structure.One pole is protected, the other pole is unprotected, and the two poles are closed and disconnected at the same time, thus solving the various hidden dangers caused by the use of only one-pole switch at the single-phase end of civil residence, and really achieving safety and reliability. Therefore, it is the most ideal power distribution protector in the residential area at present.
• Complywith: IEC60898-1,GB/T10963.1
