The Chint NXC-160 コンタクタ is a high-performance AC contactor suitable for the field of industrial control.
私. コアパラメータとパフォーマンス
1. 定格電流と電圧
This contactor has a rated current of 160A, supports the AC-3 application category (suitable for motor control), and is compatible with multiple AC voltages such as 220V, 380V, および400V (selection depends on specific models). 例えば, the model NXC-160/N 220V corresponds to a coil voltage of 220V AC, while the NXC-160 400V is suitable for 400V AC systems.
2. Contact Configuration and Service Life
The main contacts adopt a 3-pole normally open design, and the auxiliary contacts are provided with 2NC + 2いいえ (2 通常は閉まっている + 2 通常は開いています) デフォルトでは, which can meet the requirements of complex control logic. The electrical service life can reach 1.2 million times under the AC-3 category, and the mechanical service life is as high as 12 百万回, making it suitable for scenarios with frequent operations.
3. 環境適応力
The operating temperature range is -35℃ to +70℃, enabling adaptation to extreme climates; the protection class is IP50 (防塵), which can effectively resist dust intrusion and is suitable for high-dust environments such as textile and metallurgical industries.
Ⅱ. 構造設計と設置
1. モジュラー設計
It adopts a compact structure and supports DIN rail or screw mounting. Its dimensions are 156mm × 127mm × 182mm (長さ×幅×高さ), and the weight is approximately 3.46kg, facilitating dense installation in control cabinets. The main circuit wiring supports 1.5~6mm² hard wires or 1~4mm² flexible wires, and the control circuit can be connected with 1~2.5mm² wires, ensuring convenient wiring.
2. 安全機能
The coil has wide voltage adaptability (75%~120% of the rated voltage), which can reduce the risk of misoperation caused by voltage fluctuations; the contacts are made of low-resistance anti-welding materials, which reduce arc wear and improve reliability.
Ⅲ. 認証と規格
It complies with GB/T 14048.4/IEC 60947-4-1 (contactor standard) とGB 21518 (energy efficiency standard), CCC認証に合格しました. Some models may comply with CE certification (confirmation is required based on specific products).
Ⅳ. アプリケーションシナリオ
1. 産業用モーター制御
It can directly control three-phase asynchronous motors with a current below 160A, such as controlling the start, 停止, forward and reverse rotation of equipment like water pumps, ファン, とコンプレッサー. It is often used in conjunction with NXR series thermal overload relays to form an electromagnetic starter, 過負荷保護の提供.
2. 新エネルギー分野
It serves as a power switching component in photovoltaic inverters and energy storage systems, supporting high-frequency switching; in microgrid projects, it can participate in power distribution and load switching.
3. Lifting and Construction Machinery
It is suitable for frequent lifting operations of lifting equipment, has anti-vibration characteristics, and can withstand short-term overload (1.1 定格電流の倍), ensuring stability under harsh working conditions.
V. Selection and Procurement Recommendations
1. モデルの差別化
Attention should be paid to the model suffix (例えば, NXC-160/N 220V), どこ “N” stands for reversible type, and the part after “/” indicates the coil voltage. For DC control, AC/DC universal models (例えば, NXC-265 220-240V AC/DC) 選択できます.
2. 価格と供給
The reference market price is approximately 415~758 RMB (minimum order quantity: 1 ユニット), and the specific price fluctuates depending on voltage and channels. It is recommended to purchase via WhatsApp: 0086-13811255435 to ensure product quality and after-sales support.
3. 設置とメンテナンス
設置前, コイル電圧が一致しているかどうかを確認してください; 配線中, ensure that the screws are tightened (the torque of the main circuit M4 screw is 1.2N·m). Regularly clean the contact surface to prevent dust from affecting electrical conductivity.
