| DS series moulded case circuit breaker, it is suitable for
the circuit of AC 50Hz(or 60Hz), rated insulation Voltage 660V,
rated operating Voltage under AC 660V, 250V(DC), rated operating
current 10-800A. It is for distribute energy of electricity
and infrequent switchover in normal conditions. The MCCB rated
current under 400A they are provided with the function of the
protection against overload and short circuit and undervoltage.
The MCCB complies with standard of IEC947-2. |
