Terminal/Connection Bolt Rittal SV 9640.380 Silver, M16, L=30 mm

Rittal SV 9640.380 is a silver connection bolt specified as M16 with a 30 mm length, designed to provide secure electrical and mechanical connections in switchgear, control cabinets and enclosure systems. It is intended for fastening conductors with ring terminals and is compatible with busbar mounting arrangements such as Maxi-PLS1600/2000. The bolt’s design focuses on reliable conductor attachment and stable mechanical retention where a robust threaded stud is required.

Advantages

The connection bolt offers a corrosion-resistant silver finish and a standardized M16 thread size that simplifies matching with common nuts and terminal hardware. Its 30 mm length provides sufficient engagement for ring terminals and layered washers, allowing dependable clamping force. The compact, straightforward design supports easy installation and long-term electrical contact stability.

Suitable for

• Connecting cables with ring terminals in control cabinets and switchgear
• Mounting and securing busbar components in Maxi-PLS1600/2000 style systems
• Electrical conductor termination where an M16 threaded stud is specified
• Applications requiring a metal fastening stud with a 30 mm exposed length for washers and nuts

When it may not be suitable

This bolt is intended for use with ring terminals and similar terminal lugs; it may not be suitable for applications that require insulation displacement connectors, crimp-only terminations, or non-threaded fastening methods. It is also not designed as an isolating or insulating component, so it may be unsuitable where electrical isolation from the enclosure or mounting surface is required.

Key specifications

• Thread size: M16
• Length (exposed): 30 mm
• Finish/color: silver
• Primary use: connection/terminal bolt for conductor attachment
• Compatibility: suitable for use with Maxi-PLS1600/2000 style busbar/enclosure mounting systems

How to use

Prepare the conductor with an appropriately sized ring terminal and slide it over the M16 bolt. Position any required insulating or flat washers between the terminal and the mounting surface if specified. Thread on a matching nut and tighten to the torque recommended for M16 connections to ensure secure mechanical and electrical contact; avoid over-tightening which can damage terminals. Confirm that the bolt is fully seated in the mounting hole or busbar support and that the assembled joint provides firm retention and continuity.

What to consider before purchase

• Confirm that M16 thread size and 30 mm length meet the clearance and engagement needs of your enclosure or busbar assembly
• Verify compatibility with the specific Maxi-PLS1600/2000 mounting system or other intended mounting hardware
• Ensure the bolt’s metal finish and conductivity are appropriate for the electrical connection requirements in your installation
• Check required torque values for M16 terminals and the condition of mating nuts and washers

Usage recommendations

Use with properly crimped ring terminals and matching nuts/washers; follow standard electrical installation practices and torque specifications for M16 connections. Inspect connections periodically for corrosion or looseness in environments with vibration or corrosive exposure.
