Intelligent control: Choose NC5NE intelligent contactor.
Compact cabinet: Use ultra-thin NXCF.
Reactive power compensation: Special NXCC capacitor contactor.
- Current Selection
Rated current ≥ motor rated current × 1.1 (dever normal).
Frequent operation ≥ motor current × 1.25.
- Tensão da bobina
Match control circuit voltage: AC220V / AC380V most common; safety low-voltage 24V/36V optional.
