## Long description

The Siemens 3RU2916-3AA01 single installation support is a specialized mounting accessory engineered for SIRIUS 3RU21, 3RB30, and 3RB31 overload relays in size S00. This component is designed to facilitate the standalone installation of overload relays, allowing them to be mounted independently of a contactor. By enabling this flexible configuration, it assists in optimizing the layout of control cabinets and simplifies complex wiring arrangements in industrial automation environments.
Advantages
This installation support offers significant flexibility for panel builders and system integrators by decoupling the overload relay from the contactor. Its robust construction ensures a secure and stable mounting point, which is critical for maintaining the integrity of motor protection circuits. By allowing for non-direct mounting, it helps in managing space within crowded control panels and improves accessibility for maintenance and inspection tasks.
Suitable for
Standalone mounting of SIRIUS 3RU21 overload relays
Independent installation of 3RB30 and 3RB31 electronic overload relays
Control cabinet layouts requiring flexible component positioning
Industrial automation systems where contactor-mounted relays are not feasible
When it may not be suitable
This support is specifically designed for size S00 relays and will not accommodate larger relay sizes. It is not intended for applications where the relay must be directly plugged into the contactor for space-saving direct-start configurations.
Key specifications
Compatible with SIRIUS 3RU21, 3RB30, and 3RB31 series
Designed for size S00 overload relays
Supports standalone installation outside of contactors
Durable industrial-grade material construction
How to use
To use the installation support, securely fasten the unit onto a standard mounting rail or flat surface within the control cabinet. Once the support is fixed, align the compatible SIRIUS overload relay with the mounting interface and snap or screw it into place according to the specific relay model requirements. Ensure that all electrical connections are made using appropriate wiring methods to maintain the protection circuit's functionality.
What to consider before purchase
Verify that your overload relay is size S00
Confirm compatibility with your specific 3RU21, 3RB30, or 3RB31 model
Ensure there is sufficient space in the control cabinet for standalone mounting
Usage recommendations
Always ensure that the installation support is mounted on a stable, vibration-free surface to prevent mechanical stress on the relay terminals. Regularly inspect the connections to ensure they remain tight and free from debris in industrial environments.
