Application

SM6 Intelligent type MCCB is suitable for using in the circuit of AC 50/60Hz,

please make remarks when ordering, rated insulating voltage 750V, rated working voltage below 690V,

and rated current is 16A to 1250A for distributing electric energy, and infrequently OFF/ ON under normal condition.

The intelligent MCCB, which the rated frame rank current is 800A and below, also can be used for infrequently switching and start-

ing of squirrel cage motor and for protecting motor from over-load, short circuit and under-voltage.

Working conditions:

● Not over altitude 2000m;

● Ambient temperature is between-25℃ and +40℃ ; Working in the medium which not any explosive, not enough dielectric to corrode metal,

no gas to damage insulation and electric conduction dust;

● Working in the place would not be invaded by rain and snow;

● Pollution degree3;

● Mounting type.
