Bracket for strain relief ENSTO SO80S for 4×16–35 mm cables

The ENSTO bracket for strain relief SO80S is designed to secure cable assemblies with four conductors, each with a cross-sectional area between 16 and 35 mm². It provides mechanical support at junctions and connection points, reducing stress on terminations and helping prevent pull-out or movement of the cable. The bracket is intended for use in electrical installations where a robust, compact anchoring solution is required.

Advantages

This bracket offers sturdy mechanical fixation that helps maintain electrical connections under tension or vibration. Its geometry and clamping method are adapted to four-core cables within the stated conductor size range, ensuring consistent strain relief without altering cable routing. The bracket is compact and suitable for installation in confined spaces, and it is compatible with typical mounting points used in junction boxes and enclosures.

Suitable for

• Securing four-core power cables with conductor sizes from 16 mm² to 35 mm²
• Strain relief at junction boxes, panel entries, and enclosure penetrations
• Electrical installations in commercial or industrial settings requiring reliable cable anchoring

When it may not be suitable

This bracket is not intended for single-core cables or multi-core assemblies with conductors smaller than 16 mm² or larger than 35 mm². It should not be used where strain relief must also provide extensive environmental sealing, corrosion protection, or where specific certified outdoor weatherproofing is required unless combined with appropriate sealing measures and enclosure ratings.

Key specifications

• Compatible cable count: 4 conductors
• Compatible conductor cross-section: 16–35 mm²
• Function: mechanical strain relief and cable anchoring
• Typical mounting: within junction boxes, panels, or enclosures
• Form factor: compact bracket suitable for confined spaces

How to use

Position the bracket at the cable entry or termination point so that it bears the mechanical load instead of the electrical terminations. Place the cable bundle into the bracket's clamping area, align conductors as required for the installation, and fasten the bracket according to the mounting method appropriate for the enclosure (screws or clamps). Ensure the clamping force secures the cable without damaging insulation. Verify that the bracket transfers any tensile load away from connectors and that there is no stress on terminations after installation.

What to consider before purchase

• Confirm that your cable assembly has four conductors and each conductor is between 16 mm² and 35 mm²
• Check enclosure space and mounting point compatibility for bracket installation
• Assess whether additional environmental sealing or corrosion protection is required for your application

Usage recommendations

Use this bracket as the primary mechanical anchor for the cable entry; combine with cable glands or grommets if environmental sealing or strain relief plus sealing is needed. Inspect clamps and cable insulation after tightening to ensure no compression damage has occurred.
