Application NDC1N-115~780 series reversible contactor is used in AC 50Hz (or 60Hz) with rated insulating voltage of up to 1000V, rated working voltage of 400V and rated working current of 52A~234A in AC-4 type. It is used to control dual power and motors with reversible movement and braking. It can also be used as electro-magnetic starter when matched with thermal relay to protect the circuit against possible overload. Working environment and installing condition Ambient temperature: -5 oC ~+60oC Maximum altitude 3,000m The relative humidity not more than 50% at the temperature of +40 oC, the lower the temperature, the higher humidity tolerated; such as 90% humidity permissible at 20 oC. Special measures should be taken to counteract the dew caused by temperature change. The installing place has no strong vibration or impact. Screw install Installing type: "III" type Vertical install, the angle between installing surface and vertical surface should be less than +5o Pollution degree:3 Product character Direct operating mechanism, bi-breaking point Ready to take auxiliary contact groups(NF1) on both sides
