Siemens 3RU2916-3AA01 Single Installation Support for SIRIUS 3RU21, 3RB30, and 3RB31 Overload Relays Size S00

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.
