Product information

Description

The Siemens 3RQ4901-0C is an 8-pole connecting comb engineered for the efficient and reliable wiring of relay modules within control cabinets and industrial automation systems. This accessory is specifically designed to bridge identical potentials across multiple relay units, significantly reducing the time and complexity associated with manual wiring. By providing a standardized and organized connection method, it ensures consistent power distribution and a clean, professional installation in modular relay setups.

Advantages

The primary benefit of using this connecting comb is the substantial reduction in installation time and labor costs. By eliminating the need for individual jumper wires between relay modules, it minimizes the risk of wiring errors and loose connections. The robust design supports a maximum current capacity of 10A, making it suitable for demanding industrial environments where reliability is paramount. Its compact 8-pole configuration allows for high-density mounting, optimizing space within the control cabinet while maintaining clear and accessible electrical paths.

Suitable for

  • Industrial automation control panels
  • Modular relay module installations
  • Systems requiring efficient power distribution across multiple relays
  • Applications using SIRIUS relay series

When it may not be suitable

This connecting comb is designed exclusively for specific Siemens relay modules and may not be compatible with relay units from other manufacturers or different product series. It is not suitable for applications requiring individual circuit isolation or where the total current load exceeds the 10A maximum capacity.

Key specifications

  • Number of poles: 8
  • Maximum current capacity: 10 A
  • Function: Bridging identical potentials
  • Compatibility: SIRIUS relay modules

How to use

To install the connecting comb, ensure that the relay modules are securely mounted on the DIN rail and properly aligned. Insert the comb into the designated connection slots on the relay modules, ensuring that each pole makes firm contact with the terminal. Apply gentle pressure until the comb is fully seated. Verify that all connections are secure before applying power to the system. Always ensure that the total current draw of the connected modules does not exceed the 10A limit of the comb.

What to consider before purchase

  • Verify compatibility with your specific relay module model
  • Ensure the total current load of the circuit is within the 10A limit
  • Check the physical spacing and alignment of your relay modules

Usage recommendations

Always disconnect the power supply to the control cabinet before installing or modifying any electrical components. Ensure that the connecting comb is free from debris and that the relay terminals are clean to maintain optimal electrical conductivity.
