Product information

Description

The Siemens 5ST2505 is a professional 1-pole distribution block engineered for efficient power management in industrial and commercial electrical switchboards. Designed to handle high current loads, this component facilitates the organized distribution of power supply lines, ensuring that electrical installations remain tidy, safe, and easy to maintain. It is fully compatible with DIN-rail mounting, allowing for seamless integration into existing control cabinets and distribution panels alongside miniature circuit breakers and residual current devices.

Advantages

This distribution block offers exceptional reliability and safety for complex electrical systems. Its design prioritizes ease of installation, featuring a compact form factor that saves valuable space within switchgear enclosures. The unit is built with integrated touch protection, which significantly reduces the risk of accidental contact during maintenance or operation. By providing multiple connection points for varying cable cross-sections, it simplifies the wiring process and ensures a secure, low-resistance connection for all outgoing circuits.

Suitable for

  • Industrial switchboard power distribution
  • Commercial building electrical panels
  • Organizing power supply lines for circuit breakers
  • Control cabinet wiring and energy management systems

When it may not be suitable

This distribution block is intended for professional electrical installations and should not be used in environments where the voltage or current requirements exceed the specified ratings. It is not suitable for outdoor applications unless housed in an appropriately rated, weather-protected enclosure.

Key specifications

  • Number of poles: 1
  • Rated current: 125 A (IEC) / 115 A (UL)
  • Rated voltage: 1000 V AC / 1500 V DC (IEC) / 600 V AC/DC (UL)
  • Input terminals: 1x 10-35 mm² and 1x 2.5-25 mm²
  • Output terminals: 6x 2.5-16 mm²
  • Mounting type: DIN-rail

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. First, ensure the power supply is completely disconnected. Secure the distribution block onto a standard DIN-rail within the enclosure. Insert the main power cables into the designated input terminals and tighten the screws to the recommended torque. Connect the outgoing circuits to the six output terminals, ensuring that each wire is stripped to the correct length and firmly seated. Verify all connections before restoring power to the system.

What to consider before purchase

  • Verify that the total current load of your system does not exceed 125A.
  • Ensure the cable cross-sections of your installation match the terminal capacities.
  • Confirm that the DIN-rail space is sufficient for the block dimensions.
  • Check that the voltage rating meets your specific application requirements.

Usage recommendations

Always use appropriate ferrules for stranded wires to ensure a secure connection and prevent strand breakage. Regularly inspect terminal connections during routine maintenance to ensure they remain tight and free from oxidation.
