Busbar block 1-potential combined 125A Simet SCB 35-Cu — 2×4–35 mm², 2×2.5–25 mm², blue

Combined 1-potential busbar block Simet SCB 35-Cu rated for 125 A, designed to provide a compact and insulated solution for connecting and distributing a single electrical potential in switchboards and junction boxes. The unit accommodates two conductor ranges — two terminals for 4–35 mm² conductors and two terminals for 2.5–25 mm² conductors — and features a blue insulated housing with copper conductor contacts to ensure stable current transfer and organized wiring in residential and light commercial installations.

Advantages

This Simet SCB 35-Cu busbar block combines multiple conductor sizes in a single, space-saving module, reducing the number of separate terminals required. The copper contact elements provide reliable electrical conductivity and low contact resistance, while the blue insulating body offers mechanical protection and clear visual identification of the potential. Rated for up to 125 A, the block is suitable for typical distribution circuits and supports standardized installation practices in cabinets and distribution boxes.

Suitable for

• Connecting and distributing a single potential in residential switchboards
• Junction boxes and small commercial distribution panels
• Organizing multiple conductor sizes on one terminal block
• Applications requiring insulated, color-coded potential distribution

Key specifications

• Rated current: 125 A
• Conductor accommodation: two terminals for 4–35 mm² and two terminals for 2.5–25 mm²
• Conductor material contact: copper
• Housing: blue insulated plastic for potential identification
• Function: single-potential busbar block (combined conductor ranges)

How to use

Mount the busbar block inside a switchboard or junction box on a suitable DIN rail or fixed support according to the panel layout and relevant electrical standards. Strip conductors to the recommended length, insert into the appropriate terminals for their cross-section, and tighten the terminal screws to the torque specified by installation guidelines. Ensure the block is installed with correct potential labeling and that live circuits are de-energized before making connections. After wiring, verify secure mechanical fastening and perform continuity and insulation checks as part of commissioning.

Usage recommendations

Use the block for single-potential distribution where two different conductor size ranges are required. Follow applicable local electrical codes, verify conductor cross-section compatibility with the terminal ranges, and apply recommended torque values for reliable contact. Avoid overloading beyond the 125 A rating and ensure appropriate protection upstream (fuses or circuit breakers).
