GTM8(NS) series moulded case circuit breaker
One of the most advanced type breakers in the world, which adopt international advanced design and manufacture technology. They are suitate for short circuit and overload protection for circuit of AC 690V, 50/60Hz, rated current from 12.5A to 630A. Its rated insulation voltage is 690V. It can make and break non-frequent start, breaking off working and protecting overload, short circuit and under voltage.
Standard IEC 60947-2
