Terminal clamp ENSTO Zacisk CLAMPOPRO 1‑pole gray Al/Cu 35–150 mm² KE63

ENSTO Zacisk CLAMPOPRO 1‑pole gray Al/Cu 35–150 mm² KE63 is a single‑pole terminal clamp designed for mechanical and electrical connection of aluminum and copper conductors with cross‑sections from 35 to 150 mm². The connector is intended for use in power distribution and industrial installations where reliable conductor fixation and corrosion‑resistant contact between dissimilar metals are required. The gray body and compact form factor allow mounting in overhead line fittings, cable joints and distribution hardware while maintaining electrical continuity and mechanical stability.

Advantages

The clamp provides secure mechanical retention and a low‑resistance electrical contact for both Al and Cu conductors, reducing the risk of galvanic corrosion at the interface. Its design enables straightforward installation and consistent contact pressure across the conductor cross‑section range, supporting long‑term service in outdoor and indoor environments. Constructed from materials selected for conductivity and corrosion resistance, the product supports maintenance access and reliable performance under typical power distribution conditions.

Suitable for

• Connections between aluminum and copper conductors in overhead and underground networks
• Power distribution lines, service cables and feeder connections
• Cable joints, terminal blocks and industrial electrical panels requiring secure conductor fixation

Key specifications

• Number of poles: single‑pole
• Compatible conductor materials: aluminum (Al) and copper (Cu)
• Acceptable conductor cross‑section range: 35–150 mm²
• Body color: gray
• Intended applications: overhead lines, cable joints, distribution and industrial installations
• Function: mechanical clamping and electrical contact for dissimilar metal conductors

How to use

Strip the conductor insulation to the length recommended for the chosen clamp, ensuring clean, undamaged conductor ends. Position the aluminum and/or copper conductors in the clamp so that they make full contact with the contact surfaces, then tighten the fastening element to the torque specified by installation standards or project documentation to achieve secure mechanical and electrical connection. Verify mechanical retention and continuity after installation and, where applicable, apply appropriate sealing or protective measures for outdoor or exposed installations.

Usage recommendations

Use torque values and installation procedures referenced in local electrical codes and ENSTO installation guidance; avoid over‑tightening to prevent conductor deformation and under‑tightening that may increase contact resistance. When connecting dissimilar metals, ensure proper contact surfaces and consider corrosion prevention practices compatible with Al/Cu interfaces.
