DZ51-63 Series Miniature Circuit Breaker

DZ51-63 1P

1. Application
DZ51-63 is mainly suitable for overload and short circuit protection. It is especially used for illumination and distribution in industry and commerce, etc. It has pleasing outlook & high break-ing capacity, reliable performance, high inflammable resistance and shock resistance for long service life. It is within the circuit of AC 50/60Hz, rated voltage of single pole up to 240V, two, three or four poles up to 415V. It can also be used for an unfrequent change over of the circuit and illumination under normal condition.It conforms with the standards of IEC60898.
