Eaton thermal overload relay XTOG010BC1

The Eaton thermal overload relay XTOG010BC1 is a device specifically designed for motor protection, suitable for industrial control scenarios. The following is a key information summary based on search resources:  

 I. Core Technical Parameters  

1. **Current Range*Schneider-MCCB-NSX250F-4P-250A* 

   - The rated current adjustment range is **6–10A**, suitable for motors matching this current interval.  

2. **Protection Features**  

   - **Class 10 Protection**: In case of overload (e.g., motor stalling), it can quickly trigger tripping within **10 seconds** to effectively prevent motor damage.  Schneider Circuit Breakers Price* 

   - **Phase Loss Protection**: Built-in phase fault detection function, compliant with IEC/EN 60947 standards.  

   - **Environmental Compensation**: Adopts a bimetallic thermal tripping mechanism, which can automatically compensate for environmental temperature changes (-25°C to 55°C) to avoid misoperation.  

3. **Electrical Specifications**  

   - **Insulation Voltage**: 690V AC, certified by UL and CSA, suitable for the North American market.  

   - **Auxiliary Contacts**: Standard configuration includes 1 normally open (NO) and 1 normally closed (NC) contact for signal feedback in the control circuit.  

4. **Installation Method*Chint's NB1-63DC series DC circuit breakers Price*   

   - **Plug-in Design**: Can be directly installed with Eaton XTCE series contactors (such as XTCE007B10, XTCE009B10), saving space and simplifying wiring.  

   - **IP20 Protection Level**: Prevents foreign objects from entering, suitable for industrial environments.  

 II. Application Scenarios  

- **Motor Control**: Widely used for overload protection of three-phase motors such as fans, water pumps, and compressors, forming a complete motor control circuit in combination with contactors.  

- **Industrial Automation**: Supports integration with PLC or other control systems, enabling remote monitoring and fault alarm through auxiliary contacts.

 III. Installation and Usage Key Points  

1. **Type Selection and Matching**  

   - Select the corresponding specification of thermal overload relay according to the motor's rated current, ensuring the current adjustment range covers **1.1–1.25 times** the motor's full-load current.  

   - Must match the frame size of the contactor (e.g., XTOG010BC1 is suitable for XTCE 007B to XTCE015B series contactors).

2. **Wiring and Settings**  

   - **Main Circuit**: Connect the three-phase main contacts of the relay in series with the motor's power supply line.  

   - **Control Circuit**: Auxiliary contacts need to be connected to the contactor coil circuit to cut off the motor power after tripping.  

   - **Current Setting**: Adjust the current scale to the motor's rated value via the front knob. It is recommended to set it at the **lower-middle range** of the adjustment range to improve sensitivity.  

3. **Reset Modes**  

   - **Manual Reset**: After tripping, manually press the reset button, suitable for scenarios requiring manual fault confirmation.  

   - **Automatic Reset**: Automatically restores when the temperature drops, suitable for systems allowing automatic restart.  

 IV. Market and Alternative Solutions  

1. **Supply Status**  

   - As of 2025, XTOG010BC1 is still in stock with spot supply, priced at approximately **44–48 USD**.  

2. **Alternative Models**  

   - **XTOD010BC1** in Eaton's D-Line series may be an upgraded model, covering a wider current range (6–95A) and标配 auxiliary contacts. It is recommended to confirm through official channels.  

3. **Certifications and Compliance**  

   - Complies with standards such as UL, CSA, IEC/EN 60947, suitable for North American and international markets.  

V. Common Issues and Maintenance  

1. **Troubleshooting for Misoperation**  

   - **Environmental Temperature**: If the ambient temperature exceeds 55°C, it may cause the bimetallic strip to act prematurely. Strengthen heat dissipation or use with derating.  

   - **Current Setting**: Check if the setting value is lower than the motor's actual load. It is recommended to measure the motor current with an ammeter.  

2. **Contact Maintenance**  

   - Regularly clean the surface of auxiliary contacts to prevent poor contact due to oxidation. Use contact cleaners if necessary.  

3. **Fault Code Reference**  

   - In case of communication anomalies with other devices (e.g., PLC), refer to fault troubleshooting methods for similar industrial devices (e.g., check wiring and communication protocol compatibility).  

 VI. Obtaining Technical Support  

- **Official Resources**: Eaton's official website provides product manuals and technical documents, but specific materials need to be obtained by searching the model or contacting customer service.  

- **Distributor Services**: Contact Whatsapp: 0086-13811255435 for technical consultation and after-sales service. Some support online selection tools.
