Rittal SV 3559.000 Steel plate clamp, silver, for 40 mm rail, clamping space; width 34 mm, height 10 mm

Rittal SV 3559.000 is a steel plate clamp in a silver finish designed for secure mounting on 40 mm DIN rails. The clamp provides a defined clamping space for laminated or strip conductors and is intended for use in control cabinets, switchgear and industrial enclosures where a reliable mechanical and electrical fixation of plates or conductor bars is required. Its compact dimensions — 34 mm width and 10 mm height — make it suitable for installations with limited space while maintaining sturdy steel construction for long-term durability.

Advantages

The steel construction ensures mechanical strength and resistance to deformation under load. The silver finish improves corrosion resistance and offers a neutral appearance that integrates well into industrial panels. The clamping space is tailored for laminated copper bars and strip connections, enabling reliable electrical contact without the need for drilling. Its design for 40 mm rails allows fast mounting and straightforward positioning in standard switchgear systems.

Suitable for

• Fixing laminated copper bars or strip conductors on 40 mm DIN rails
• Securing small steel plates or mounting components inside control cabinets
• Use in switchgear and distribution panels where compact clamping hardware is required
• Applications that require mechanical retention combined with electrical contact

When it may not be suitable

This clamp is intended specifically for 40 mm rail systems and strip or laminated conductors; it may not fit non-standard rail widths or alternative mounting profiles. For very large conductor cross-sections, heavy current busbars, or applications requiring insulation barriers or specialized electrical isolation, this clamp may not provide the necessary dimensions or protective features.

Key specifications

• Material: steel
• Finish: silver
• Designed rail width: 40 mm
• Clamping space: suitable for strip/laminated conductors
• Overall width: 34 mm
• Overall height: 10 mm

How to use

Position the clamp on the 40 mm rail at the desired location and engage the clamp so that the clamping space accommodates the laminated or strip conductor. Ensure the conductor is seated fully in the clamping channel and that the clamp is tightened or secured according to the mounting method used so there is reliable mechanical retention and electrical contact. No drilling of the conductor is required for installation. Verify alignment and clearances inside the enclosure before closing the cabinet.

What to consider before purchase

• Confirm compatibility with a 40 mm DIN rail profile
• Check conductor dimensions to ensure they fit the clamping space
• Evaluate whether steel material and silver finish meet environmental and corrosion requirements
• Determine if additional insulation or separation components are needed for your electrical application

Usage recommendations

Use the clamp with properly sized laminated copper bars and verify that mounting torque or securing method follows cabinet assembly rules. For installations exposed to corrosive environments or high currents, consider corrosion protection and appropriate cross-section rated hardware to maintain long-term performance.
