Mounting Bracket ENSTO PAS for Strain Relief 50–70 mm² with Breakaway Head SO255S

ENSTO PAS mounting bracket with a breakaway head (SO255S) is designed to provide reliable strain relief for conductors with cross-sections from 50 to 70 mm². The metal bracket secures medium-voltage cables in overhead and distribution network installations and incorporates a pre-weakened head that allows controlled release under excessive tension, helping to protect terminations and connection points from mechanical damage. The compact design supports straightforward installation on poles, towers and fixed anchors.

Advantages

The bracket combines corrosion-resistant metal construction with a breakaway head engineered to fail predictably under overload, reducing the risk of damage to connectors and insulators. Its geometry is optimized for secure clamping of 50–70 mm² conductors while allowing easy routing and anchoring of cables. The product is compatible with standard pole and support mounting arrangements used in overhead and distribution networks and is suitable for long-term outdoor use when installed according to manufacturer recommendations.

Suitable for

• Strain relief for medium-voltage conductors 50–70 mm²
• Overhead line terminations and anchor points
• Cable routing and support in distribution networks
• Installations requiring controlled release to protect terminations

Key specifications

• Conductor cross-section compatibility: 50–70 mm²
• Material: corrosion-resistant metal construction
• Breakaway head with pre-weakened release point for controlled failure
• Intended application: overhead and distribution network strain relief
• Mounting: designed for pole, tower and fixed anchor installations

How to use

Position the bracket at the chosen anchor point and secure it to the pole or support using appropriate fasteners for the installation substrate. Place the conductor within the clamping area suitable for 50–70 mm² cables and tighten the clamp according to the recommended torque for the connection hardware used. Ensure the breakaway head is oriented so that, in the event of excessive load, the head will separate in the intended direction away from critical terminations. After installation, check mechanical security and clearances to nearby components.

Usage recommendations

Install and maintain the bracket following local electrical codes and the conductor manufacturer's guidance. Use corrosion-resistant fasteners and ensure correct torque values for secure clamping. Periodically inspect the bracket and surrounding hardware for corrosion, deformation or signs of unintended loading; replace if the breakaway head shows evidence of compromise or if mechanical integrity is affected.
