KNM3 Series moulded-case circuit-breakers guarantee an extremely high performance level while being progressively smaller in size, simple to install and able to provide increasingly better safety guarantees for the operator.
KNM3 Series Moulded-case circuit-breakers can be used in low voltage civil and industrial installations with 1 to 3200 A operating current.
Since assembly instructions are simple, trip units can quickly and easily be replaced; even in the field.
All this makes the circuit-breakers very easy to operate with considerable savings due to rationalized stock management.
This product complies with standard IEC60947-2, GB14048.2
