Symmetrical ladder reducer RDSC400/300H50 N 457940

Ladder Reducer – Efficient Transition Between Sections

This symmetrical ladder reducer, designated as RDSC400/300H50 N, is a key component of cable ladder systems, enabling seamless connection and width transition between cable ladders. It allows installations to adapt to changing requirements and configurations, ensuring flexibility in cable routing. Essential for designing and constructing electrical installations in public buildings, industrial halls, and other facilities requiring a robust and safe cable ladder system.

Design and Application

Manufactured from high-strength steel, the reducer offers excellent resistance to mechanical loads and corrosion—especially when selecting the hot-dip galvanized variant. Its symmetrical design ensures even load distribution and stable connections. The width reduction from 400 mm to 300 mm enables precise adaptation of the cable ladder route to the specific layout of the installation. A sheet thickness of 2.0 mm guarantees sufficient rigidity and structural strength.

For proper installation, LDCH… connectors and SGKM8x14 or SGM8x14 screws (4 connectors and 16 screw sets required) are necessary. For non-standard orders, it is essential to specify exact dimensions 'a' and 'b' to ensure perfect compatibility with existing installations.

Materials and Protective Coatings

The reducer is available in multiple material variants:

• Hot-dip galvanized steel (S): Standard finish providing adequate corrosion protection under typical operating conditions (compliant with PN-EN 10346:2015-09).
• Hot-dip galvanized steel (F): Superior corrosion resistance, ideal for outdoor or aggressive environments (compliant with PN-EN ISO 1461:2023-02).
• Stainless steel (E): Maximum corrosion resistance, recommended for harsh environmental conditions.
• Powder coating in standard RAL color (L): Option to match the color to the environment or design requirements.

Selecting the appropriate material allows the reducer to be tailored to specific operational conditions and project requirements. Hot-dip galvanizing further enhances structural durability by protecting against atmospheric exposure.
