Rittal Reitersicherungselement SV 3427.040, polyester grey (RAL 7035), mounting for busbar, 56 x 251 mm

Rittal Reitersicherungselement SV 3427.040 is a polyester grey (RAL 7035) mounting element designed for secure attachment and insulation of fuse-holders and other components on busbar systems. With dimensions of 56 x 251 mm, this element is intended for use in industrial electrical cabinets and switchgear where compact, insulated mounting on Sammelschienen S (busbars) is required.

Advantages

The polyester construction provides electrical insulation and resistance to common industrial environmental conditions. Its standardized dimensions and form factor enable consistent alignment and reliable fixing on busbar systems. The neutral RAL 7035 colour integrates with typical enclosure interiors and helps maintain clear component organisation.

Suitable for

• Mounting fuse-holders and small protective devices on busbar Sammelschienen S
• Installation inside industrial control cabinets and distribution panels
• Applications requiring insulated mounting points in switchgear
• Retrofit or new-build electrical distribution systems with standard busbar profiles

When it may not be suitable

This mounting element is sized and shaped specifically for busbar-mounted components; it is not intended as a primary structural support for heavy equipment. It is made of polyester and therefore may not be suitable where metal mounting brackets or higher mechanical impact resistance are required.

Key specifications

• Material: polyester (insulating)
• Colour: grey (RAL 7035)
• Dimensions: 56 x 251 mm
• Mounting type: for attachment to busbar systems (Sammelschienen S)
• Application environment: industrial electrical cabinets and switchgear

How to use

Position the Reitersicherungselement on the busbar profile according to the busbar manufacturer’s guidance and secure it using the recommended fastening method. Place the fuse-holder or required component onto the mounting element and verify correct alignment and insulation between conductive parts. Ensure that all connections are tightened to the specified torque and that the assembly complies with applicable electrical installation standards.

What to consider before purchase

• Compatibility with the specific busbar profile (Sammelschienen S) in your installation
• Required mechanical strength and impact resistance for the intended location
• Space and clearance inside the electrical cabinet for the 56 x 251 mm element
• Compliance with local electrical codes and standards for insulated mounting elements

Usage recommendations

Use the mounting element only with compatible busbar systems and follow the cabinet manufacturer’s and local regulations when installing fuses or protective devices. Regularly inspect installations for secure fastening and signs of wear or heat.
