ENSTO strain relief bracket SO118.1201S for 4 conductors 50–120 mm²

ENSTO strain relief bracket SO118.1201S for 4 conductors 50–120 mm² is a hardware accessory intended to secure and support medium- to large-section electrical conductors at termination points. The bracket accepts four parallel conductors with cross-sectional areas between 50 and 120 mm², delivering mechanical retention that reduces tensile stress on conductor joints and terminations. It is suitable for industrial installations, utility networks and locations that require reliable pull-out protection for power cables, with options for indoor and outdoor mounting where compatible with the installation environment.

Advantages

The bracket offers robust mechanical support for four conductors within the specified cross-section range, helping to maintain secure electrical connections and reduce the risk of conductor displacement. Its design facilitates tidy cable routing and strain distribution, which can improve the long-term reliability of terminations. Constructed for installation in demanding environments, the product enables straightforward attachment to mounting points and is compatible with common cable handling practices for medium- and large-section power conductors.

Suitable for

• Securing power cables in industrial switchgear and distribution panels
• Utility and substation terminations requiring pull-out protection
• Indoor or sheltered outdoor cable terminations where mechanical retention is needed
• Installations with four parallel conductors sized 50–120 mm²

When it may not be suitable

This strain relief bracket is not intended for conductors outside the 50–120 mm² range or for single-conductor installations that do not match the four-conductor layout. It may not be appropriate where specific environmental resistance (for example, particular chemical exposures or continuous immersion) is required unless the installation environment and fasteners meet those conditions. Verify compatibility with conductor insulation types and local electrical regulations before selection.

Key specifications

• Number of conductors: 4
• Supported conductor cross-section range: 50–120 mm²
• Function: mechanical strain relief / cable retention
• Intended mounting: fixed mounting for termination points (indoor and compatible outdoor locations)
• Application area: medium- to large-section power conductors, industrial and utility installations

How to use

Position the bracket at the cable termination point and secure it to a suitable mounting surface using appropriate fasteners rated for the installation environment. Route the four conductors through the bracket so that each conductor is properly seated and clamped according to the installer’s practice and the electrical code. Ensure that mechanical loads are transferred to the bracket rather than the electrical connections, and tighten any clamps or securing elements to the manufacturer-recommended torque values if provided. After installation, inspect the termination to confirm conductor alignment, clamp security and absence of undue bending or kinking.

What to consider before purchase

• Confirm that conductor cross-sections fall within the 50–120 mm² range and that four conductors are required
• Check mounting location compatibility and select suitable fasteners for the mounting surface and environment
• Verify that the bracket’s material and finish meet any environmental or corrosion-resistance needs for the site
• Ensure compliance with relevant local electrical standards and installation practices

Usage recommendations

Use the bracket with correct-sized clamps and appropriate torque settings; where possible, combine with additional mechanical supports or drip loops for outdoor runs to reduce environmental stress and water ingress risk. Regularly inspect terminations for mechanical integrity as part of maintenance schedules.
