The Siemens 3RN2010-1BA30 is a thermistor motor protection relay that serves as a standard evaluation unit for safeguarding motors in industrial applications. This compact device, with a width of just 22.5 mm, is designed for easy installation on a standard 35 mm mounting rail, making it a space-saving solution for control cabinets.
Equipped with screw terminals, the 3RN2010-1BA30 features two change-over contacts and operates with a control supply voltage of 24 V AC/DC. It is engineered for auto-reset functionality and is compatible with bimetallic switches, enhancing its versatility in various motor protection schemes.
The unit boasts two LEDs that indicate 'READY' and 'TRIPPED' statuses, providing clear and immediate visual feedback on the operational state of the motor. This is particularly useful for maintenance personnel to quickly diagnose issues.
With an insulation voltage rated at 300 V for overvoltage category III and a surge voltage resistance of 4 kV, the 3RN2010-1BA30 ensures reliable performance even in environments with potential electrical disturbances. The protection class IP20 denotes that the device is protected against solid objects larger than 12.5 mm, making it suitable for general industrial environments.
The relay's mechanical service life is impressive, with up to 10 million switching cycles, and its electrical endurance is rated for 100,000 cycles at AC-15 at 230 V, indicating a long-lasting and durable performance. The thermal current of the switching element with contacts is a maximum of 5 A, and the device is designed to withstand vibrations in accordance with IEC 60068-2-6 standards.
For applications that demand consistent and reliable motor protection, the Siemens 3RN2010-1BA30 is a robust and efficient choice that meets the rigorous demands of industrial motor control and safety.

What is the purpose of this thermistor motor protection relay?
The thermistor motor protection relay is designed to protect motors from overheating by monitoring the temperature via connected PTC thermistors. When a preset temperature limit is exceeded, it triggers an alarm or shuts down the motor to prevent damage.
Can this device be used with both AC and DC control supply voltages?
Yes, the relay is compatible with both AC and DC control supply voltages, specifically rated at 24 V for both AC (at 50/60 Hz) and DC.
What type of terminals does the relay have for electrical connections?
The relay is equipped with screw-type terminals for secure and reliable electrical connections.
Is the relay suitable for use with bimetallic switches?
Yes, the relay is suitable for use with bimetallic switches, providing additional flexibility in motor protection applications.
What are the dimensions of the relay?
The relay has a height of 100 mm, a width of 22.5 mm, and a depth of 90 mm, making it compact and suitable for standard mounting rails.
What is the ambient temperature range for operating this relay?
The relay can operate within an ambient temperature range of -25 to +60 degrees Celsius, ensuring reliable performance in various environments.
Does the relay have LED indicators?
Yes, it features two LED indicators labelled 'READY' and 'TRIPPED' to provide visual status feedback.
What is the insulation voltage rating for this relay?
The insulation voltage rating for the relay is 300 V for overvoltage category III with a degree of pollution 3, according to IEC 60664.
