DPX series is one of the most advanced type breakers in the world,
Which adopt international advanced design and manufacture technology.
They are suitable for short circuit and overload protection for circuit of AC 690V, 50/60Hz,
Rated current from 12.5 to 1600A 3P 4P ALLOWED. It can make and break non-frequent, breaking off working and protecting overload, short circuit and under voltage.
It con-forms to IEC60947-2 standard
