Schneider-AC-contactor-LC1-E160F5N

The Schneider-AC-contactor-LC1-E160F5N is a high-performance AC contactor launched by Schneider Electric, specifically designed for industrial motor control and electrical load switching. The following is a detailed description of its technical parameters, application scenarios, and purchasing suggestions:

I. Core Technical Parameters

1. **Rated Current and Usage Category**

   - **AC-3 Category** (Motor Control): 160A, suitable for three-phase asynchronous motors with a power ≤ 80kW (such as under a voltage of 440V).

   - **AC-1 Category** (Non-inductive Load): 200A, which can be used for non-motor loads such as resistance furnaces and capacitor banks.

2. **Coil Voltage and Model Suffix**  YouTube：https://youtube.com/shorts/UI-AfalfYWw 

   - It supports a variety of AC and DC voltage specifications. The meanings of common model suffixes are as follows:

     - **F5N**: 110V AC (standard model).

     - **M5N**: 220V AC, **Q5N**: 380V AC, **B5N**: 24V AC (customization required).

3. **Contact Configuration**

   - **Main Contacts**: 3 normally open (NO), supporting the 380V/440V main circuit.

   - **Auxiliary Contacts**: It has 1 normally open (NO) + 1 normally closed (NC) built-in, and can be expanded to 4 groups (needs to be matched with the F4-22 auxiliary contact group).

4. **Mechanical and Electrical Life**

   - Mechanical life: 4 million times, electrical life (AC-3): 0.8 million times, supporting frequent operation (1200 times per hour).

5. **Certification and Compliance**

   - It complies with the standards of IEC 60947-4-1 and GB 14048.4, has passed the CCC, EAC, and CE certifications, and supports the RoHS/REACH environmental protection directives.

II. Typical Application Scenarios

1. **Industrial Motor Control**

   - Widely used for the start and stop control of equipment such as fans, pumps, and compressors. It needs to be used in conjunction with a **thermal relay** (such as the LR2 series) to achieve overload protection.

2. **Automation Systems**

   - Control the coil through a PLC or a relay to achieve remote automated operation, and support linkage with Schneider's Tesys series products.

3. **Electrical Load Switching**

   - It can control non-motor loads such as resistance furnaces and capacitor banks, but attention should be paid to the current limit of the AC-1 category.

4. **Harsh Environments**

   - The operating temperature range is from -5°C to 55°C. It supports operation without derating below an altitude of 3000 meters, and the protection level is IP20.

 III. Installation and Selection Guidelines

1. **Installation Methods**

   - **Rail Installation**: It supports the 35mm standard DIN rail and can be quickly fixed without tools.

   - **Screw Installation**: Use M4/M5 screws to fix the base, which is suitable for complex cabinet layouts.

2. **Wiring Specifications**

   - **Main Circuit**: Connect the three-phase power supply (L1/L2/L3) to the inlet terminal of the main contacts, and connect the load (such as a motor) to the outlet terminal.

   - **Control Circuit**: According to the type of coil voltage, connect the control signal (such as the output of a PLC) to the coil terminals (A1/A2). For example, the F5N model needs to connect the 110V AC phase wire (L) and the neutral wire (N).

3. **Selection Precautions**

   - **Load Type**: Select the AC-3 or AC-1 usage category according to the motor or resistance load.

   - **Coil Voltage**: Be sure to match the control circuit voltage to avoid burning out the coil (for example, F5N corresponds to 110V AC).

   - **Expansion Requirements**: If more auxiliary contacts are needed, you can match the **F4-22** or **F4-44** auxiliary contact group.

IV. Price and Supplier Information

1. **Market Price Range**

   - Standard model (such as LC1-E160F5N): The quotation of domestic authorized dealers is about **¥800-1200**, and the quotation on international platforms (such as ondustrial.com) is about **6,150 EGP** (approximately equivalent to 2,500 yuan).

   - Special configuration (such as DC coil): The price increases by 10%-20%.

2. **Supplier Channels**

   - **Domestic Authorized Dealers**:

     - **Nuoyi Electric**: A national first-class dealer of Schneider medium-voltage/low-voltage circuit breakers, covering the whole country and overseas.

     - **Alibaba Suppliers**: Provide the LC1-E160F5N in stock, with a price of about ¥42.00-¥7,005.00 (pay attention to the accuracy of the model suffix).

   - **International Suppliers**:

     - **Schneider Electric Official Website**: Query local authorized dealers through the "Distributors" page.

     - **Industrial Product Platforms**: Such as RS Components, Kempston Controls.

V. Alternative Models and Compatibility

1. **Domestic Alternatives**

   - **Chint NC1-16011**: Current 160A, AC-3 category, with a price of about ¥500-700, but the auxiliary contacts need to be expanded additionally.

   - **Delixi CDZ1-160**: Supports the AC-3/AC-1 dual mode, with a price of about ¥600-800.

2. **International Brand Alternatives**

   - **ABB T4E**: Rated current 170A, AC-3 category, with a price of about ¥1,500-2,000.

   - **Siemens 3TF53**: 160A, AC-3 category, with a price of about ¥1,300-1,800.

3. **Compatibility Comparison**

   - **Size**: The width of the Schneider LC1-E160F5N is 120mm, which is close to that of the ABB T4E (110mm) and Siemens 3TF53 (125mm), and can be directly replaced.

   - **Accessories**: The auxiliary contact group and coil adapter need to be purchased separately, and are not universal among different brands.

VI. Maintenance and Fault Troubleshooting

1. **Regular Maintenance**

   - **Clean the Contacts**: Wipe the oxide on the surface of the main contacts with alcohol to avoid an increase in contact resistance.

   - **Check the Connections**: Ensure that the screws are tightened to prevent loosening caused by vibration.

2. **Common Fault Handling**

   - **The Coil Does Not Pull In**: Check whether the coil voltage, control signal, and wiring are normal, and replace the coil if necessary.

   - **Contact Adhesion**: Overload or short circuit may cause the contacts to be ablated, and the contactor or contact module needs to be replaced.

   - **Abnormal Noise**: When there is foreign matter in the iron core or the spring is fatigued, it is necessary to clean or replace the iron core components.
