Product information

Description

The Siemens SIRIUS 3RU2 thermal overload relay is a high-performance protective device engineered to safeguard motors and electrical systems from the risks of thermal overload and phase failure. Designed for precision and reliability, this S00 size relay provides an adjustable current range of 7 to 10 A, making it an essential component for maintaining operational safety in industrial automation environments. Its robust construction ensures consistent performance under demanding conditions, while its compatibility with standard contactors facilitates seamless integration into existing control circuits.

Advantages

This thermal overload relay offers exceptional operational stability and long-term durability, which are critical for minimizing downtime in industrial processes. The device is built to withstand harsh environments, ensuring that motors are protected against excessive heat and electrical faults. Its compact S00 design allows for space-efficient mounting, while the adjustable current setting provides the flexibility needed to match specific motor requirements accurately. The integration process is straightforward, reducing installation time and complexity for maintenance teams.

Suitable for

  • Industrial motor protection
  • Control cabinet automation
  • HVAC system management
  • Conveyor belt control systems
  • Pump and compressor protection

When it may not be suitable

This device is not intended for applications requiring current ranges outside of the 7 to 10 A threshold. It is also not suitable for direct short-circuit protection, as it is designed specifically for thermal overload and phase failure monitoring.

Key specifications

  • Current setting range: 7 to 10 A
  • Size: S00
  • Protection type: Thermal overload and phase failure
  • Compatibility: Standard industrial contactors

How to use

The relay is designed to be mounted directly onto a compatible contactor or installed as a standalone unit using a mounting bracket. Once installed, the current setting should be adjusted using the dial on the front of the device to match the rated current of the motor being protected. After the settings are configured, the control circuit wiring is connected to the terminals. The device features a manual or automatic reset function, which can be configured based on the specific requirements of the application.

What to consider before purchase

  • Verify that the motor's rated current falls within the 7 to 10 A range.
  • Ensure the relay size S00 is compatible with your existing contactor model.
  • Check the environmental conditions of the installation site to ensure they meet the device's operational specifications.

Usage recommendations

Regularly inspect the relay for signs of wear and test the trip function periodically to ensure that the protection mechanism remains fully operational and responsive to potential faults.
