Terminal connector Simet ZSO 1-35 T-703, threaded rail splice for 1–35 mm² conductors

Simet ZSO 1-35 T-703 is a threaded rail splice connector engineered for joining busbars and conductors with cross-sections from 1 to 35 mm². Designed for rail-mounted installations, distribution panels and junction boxes, this terminal connector ensures a robust mechanical and electrical connection for switchboards, control cabinets and industrial electrical assemblies where a secure splice of conductors or rails is required.

Advantages

The threaded design provides reliable clamping force and consistent contact pressure across the conductor. Manufactured for compatibility with a range of conductor sizes, the connector enables straightforward installation on standard mounting rails and offers corrosion-resistant conductive surfaces for stable electrical performance. Its compact profile allows space-efficient routing within panels and helps maintain clear separation between adjacent connections.

Suitable for

• Splicing busbars in distribution panels and switchboards
• Connecting conductors in control cabinets and junction boxes
• Rail-mounted electrical assemblies in industrial installations
• Field or workshop rail splicing and repair tasks

Key specifications

• Conductor cross-section compatibility: 1–35 mm²
• Threaded rail splice type suitable for standard mounting rails
• Mechanical connection method: threaded clamping for secure contact
• Compact form factor for space-efficient panel installation
• Material and surface treatment: conductive and corrosion-resistant finish

How to use

Prepare the conductor ends by stripping insulation to the recommended length and ensure contact surfaces are clean and free of oxidation. Position the conductor or busbar into the connector and engage the threaded clamping mechanism; tighten to the torque recommended by assembly practices for the conductor size to obtain firm mechanical and electrical contact. Verify alignment on the mounting rail and confirm there is no movement or visible gap after tightening. Where multiple connections are present, maintain proper spacing to avoid contact between adjacent terminals.

Usage recommendations

Inspect the connector periodically for signs of loosening or corrosion in environments with vibration or aggressive conditions. Use appropriate torque tools and follow local electrical codes and safety practices when installing and servicing the connector.
