Product information

Description

The Siemens LZS:RT78725 is a professional-grade plug-in relay base engineered for seamless integration into industrial control and automation systems. Designed with a compact 15mm width, this base facilitates space-efficient installation on standard DIN rails, making it an ideal choice for control cabinets where panel space is at a premium. It features robust screw terminals that ensure secure and reliable electrical connections for compatible SIRIUS relays, supporting consistent performance in demanding environments.

Advantages

This relay base offers exceptional reliability and ease of maintenance for complex electrical systems. The screw terminal design provides a high-integrity connection that resists vibration and mechanical stress, ensuring long-term operational stability. Its standardized 15mm footprint allows for high-density mounting, which helps optimize the layout of control panels. Furthermore, the base is built to the high quality standards associated with the Siemens SIRIUS range, ensuring compatibility and durability across various industrial applications.

Suitable for

  • Industrial automation and control systems
  • Control cabinet assembly and wiring
  • Integration with SIRIUS series relays
  • DIN rail mounted electrical distribution

This product may not be suitable for applications requiring high-current switching beyond the rated capacity of the base or for environments with extreme moisture or corrosive gases that could compromise the screw terminal integrity. It is also not intended for direct use in high-voltage power distribution networks without appropriate relay protection.

Key specifications

  • Width: 15mm
  • Connection type: Screw terminals
  • Mounting: DIN rail
  • Compatibility: SIRIUS relay series

To use the Siemens LZS:RT78725, snap the base onto a standard DIN rail until it clicks into place. Insert the compatible relay into the socket, ensuring the pins are correctly aligned with the terminal slots. Tighten the screw terminals firmly to secure the incoming and outgoing wires, ensuring that the wire gauge used is appropriate for the terminal capacity to prevent loose connections or overheating.

What to consider before purchase

  • Verify the compatibility of your specific relay model with the base
  • Ensure the 15mm width fits your current DIN rail layout
  • Confirm that your wiring tools are compatible with the screw terminal design
For optimal performance and safety, ensure that all electrical connections are tightened to the manufacturer's specified torque and that the relay base is installed in an environment free from excessive dust and moisture.
