Terminal block Rittal SV 9650.325 — connection terminal, copper/silver finish

Rittal SV 9650.325 — connection terminal, copper/silver finish is a heavy-duty electrical terminal block intended for secure, low-resistance connections of round conductors. Designed for industrial control panels, switchgear and terminal strips, this terminal accommodates single-wire and multi-wire round conductors in the range 95 to 300 mm² and uses copper with a silver finish to provide reliable conductivity and improved corrosion resistance under demanding conditions.

Advantages

This connection terminal provides robust mechanical clamping and low electrical resistance thanks to its copper core and silver-plated contact surfaces. Its design supports both single-wire and multi-wire round conductors from 95 to 300 mm² which simplifies installation across a range of heavy-current applications. The material choice and finish enhance long-term contact stability and reduce maintenance frequency in industrial electrical assemblies.

Suitable for

• Industrial control panels and distribution blocks
• Switchgear and power distribution cabinets
• Terminal strips for heavy-current connections
• Connections requiring low-resistance, corrosion-resistant contacts

When it may not be suitable

This terminal block is intended specifically for round conductors within the 95–300 mm² range; it is not suitable for substantially smaller gauge wiring or flat/insulated busbar connections that require different types of terminals. Applications that require tool-less or miniature terminal blocks for signal-level wiring are outside the intended use of this heavy-current component.

Key specifications

• Conductor type: round conductors, single-wire and multi-wire
• Conductor cross-section range: 95–300 mm²
• Contact material: copper with silver finish
• Application area: heavy-current connections in control panels, switchgear and terminal strips

How to use

Prepare the round conductor by stripping insulation to the appropriate length and ensure strands are clean and untwisted for multi-wire conductors. Insert the conductor into the terminal bore and fasten using the recommended torque value for the clamping screw or bolt to achieve a secure mechanical and electrical connection. Verify tightness after initial power-up and re-check as part of routine maintenance to ensure continued low-resistance contact.

What to consider before purchase

• Confirm conductor cross-section falls within 95–300 mm² and that conductors are round (Cu/Al).
• Ensure compatibility with your panel or mounting system and available space for a heavy-current terminal.
• Verify the required clamping hardware and torque specifications for safe installation.
• Assess whether silver-plated contacts are needed for your environmental and corrosion conditions.

Usage recommendations

Use appropriate torque settings during installation, follow the equipment manufacturer’s grounding and bonding practices, and perform periodic inspection of connections in high-current installations to maintain reliable performance.
