NS-100n/3p Moulded Case Circuit Breaker is one of the most advanced type breakers in theworld, which adopts international advanced design and manufacture technology. They aresuitable for short circuit and overload protection for circuit of AC 690V 50/60Hz, rated currentfrom 12.5A to 630A.Its rated insulation voltage is 690V. It can make and break the nonfrequentlycircuit in the normal conditions. It takes protect effect when mouse cage motorsnon-frequent start, breaking off working and protecting overload, short circuit and lackingvoltage.
