Product information

Description

The Siemens 3RU2116-4AB0 is a professional-grade thermal overload relay engineered to provide robust protection for electric motors against thermal overloads and phase failures. Designed for seamless integration into industrial control panels, this device offers precise current monitoring within an adjustable range of 11 to 16 amperes. Its compact S00 frame size makes it an efficient choice for space-constrained electrical cabinets, ensuring reliable performance and longevity for connected motor equipment.

Advantages

This thermal overload relay stands out due to its high reliability and precision in detecting thermal stress, which helps prevent costly motor damage and unplanned downtime. The adjustable current setting allows for flexible configuration to match specific motor requirements, while the compact S00 design facilitates easy installation alongside contactors. Built to withstand demanding industrial environments, it provides consistent operational safety and supports the longevity of automation systems.

Suitable for

Industrial motor starter configurations
Automation and control systems
HVAC equipment and pump control
Conveyor belt motor protection
General manufacturing machinery

When it may not be suitable

This device is not intended for applications requiring protection against short-circuit currents, as it must be paired with appropriate fuses or circuit breakers for that purpose. It is also not suitable for motors operating outside the specified 11-16A current range.

Key specifications

Current setting range: 11-16A
Size: S00
Protection type: Thermal overload and phase loss
Mounting: Direct mounting to contactor or standalone
Reset function: Manual or automatic

How to use

The relay is typically mounted directly onto the load side of a compatible Siemens S00 contactor. Once installed, the desired current value should be set using the adjustment dial on the front of the device to match the rated current of the motor. Ensure that all electrical connections are tightened according to the specified torque requirements. The device can be configured for manual or automatic reset depending on the specific safety requirements of the application.

What to consider before purchase

Verify that the motor full-load current falls within the 11-16A range
Ensure compatibility with the S00 contactor series
Check if manual or automatic reset is required for your safety protocol
Confirm the environmental conditions of the installation site

Usage recommendations

Regularly inspect the relay for signs of wear and verify that the current setting remains calibrated to the motor's nameplate data to ensure optimal protection.
