Electrical enclosure strain relief connector Rittal 9686.250 — screw mounting, copper material

Rittal 9686.250 is an electrical enclosure strain relief connector designed for screw mounting and manufactured from copper. It secures cables and conductors where they enter cabinets and enclosures, providing mechanical retention and a reliable conductive path for grounding or potential equalization. The component is intended for industrial cabinet and enclosure installations, including power distribution and control panels where stable cable anchoring and electrical continuity are required.

Advantages

The copper construction offers good electrical conductivity and corrosion resistance appropriate for earthing and potential equalization applications. Screw mounting provides a firm mechanical connection to the enclosure, simplifying installation and ensuring long-term retention of conductors. The connector is designed to integrate with typical busbar and conductor systems used in industrial enclosures, allowing a compact installation that maintains mechanical stability under normal operational loads.

Suitable for

• Securing and anchoring power conductors entering electrical cabinets and control panels
• Connecting main busbar systems between enclosures
• Providing grounding or potential equalization in industrial enclosures
• Applications where a screw-mounted, metallic strain relief is preferred for mechanical and electrical continuity

When it may not be suitable

The connector is intended for applications compatible with copper material and screw mounting; it may not be suitable where non-metallic or insulated strain reliefs are required for chemical resistance or isolation. It is also not appropriate for installations that demand integrated cable glands with sealing against water ingress or for environments requiring certified IP-rated cable entry seals unless additional sealing components are used.

Key specifications

• Mounting type: screw mounting to enclosure
• Material: copper
• Function: strain relief and conductive connection for conductor entries
• Typical application: busbar connection and conductor anchoring between enclosures

How to use

Install the connector by securing it to the enclosure using the designated screw points, ensuring the mating surface is clean and flat for good mechanical and electrical contact. Position conductors or busbars into the connector according to the enclosure layout, then tighten screws to the recommended torque for copper hardware to achieve secure mechanical clamping and electrical continuity. After installation, verify physical retention of conductors and check continuity if used for grounding or potential equalization. If environmental sealing or additional mechanical protection is needed, add appropriate gaskets or cable glands as a separate step.

What to consider before purchase

• Compatibility with the enclosure design and available screw mounting points
• Conductor or busbar dimensions to ensure proper fit and clamping
• Material suitability for the intended electrical and environmental conditions (copper behaviour in the installation environment)
• Whether additional sealing or insulation components are required for ingress protection or isolation

Usage recommendations

Use appropriate torque settings for copper connections, verify electrical continuity when used for grounding, and combine with suitable sealing components if installation requires protection against moisture or contaminants.
