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:
- Core Technical Parameters
- Current RangeSchneider-MCCB-NSX250F-4P-250A
– The rated current adjustment range is 6–10A, suitable for motors matching this current interval.
- 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.
- 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.
- Installation MethodChint’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.
- 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
- 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).

- 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.
- 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.
- Market and Alternative Solutions
- Supply Status
– As of 2025, XTOG010BC1 is still in stock with spot supply, priced at approximately 44–48 USD.
- 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.
- Certifications and Compliance
– Complies with standards such as UL, CSA, IEC/EN 60947, suitable for North American and international markets.
- Common Issues and Maintenance
- 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.
- Contact Maintenance
– Regularly clean the surface of auxiliary contacts to prevent poor contact due to oxidation. Use contact cleaners if necessary.
- 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).
