Terminal block / pin block Rittal SV 9342.820, polyamide, black

Rittal SV 9342.820 is a black polyamide terminal block designed for use in electrical enclosures, control cabinets and starter assemblies. The component secures electrical connections and provides mechanical support for contactors and auxiliary parts, offering insulating properties and a compact mounting solution for industrial switchgear and automation panels.

Advantages

The polyamide construction delivers durable electrical insulation and resistance to common industrial conditions. Its compact design allows reliable fixation of contactors and auxiliary components while saving space inside enclosures. The terminal block is engineered for straightforward mounting and stable retention of pins and terminals, reducing the risk of loose connections in vibrating or high-use environments.

Suitable for

• Control cabinets and electrical distribution panels
• Starter assemblies and motor control centers
• Mounting contactors, relays and auxiliary components
• Applications requiring insulated pin/terminal fixation in industrial enclosures

When it may not be suitable

This terminal block is intended for mechanical support and insulation of pins and terminals; it is not a live conductor or a replacement for fused protective devices. It may not be suitable where metal mounting brackets or higher mechanical strength under extreme loads are required, or where the specific mounting geometry of a given contactor differs from the block's form factor.

Key specifications

• Material: polyamide (technical plastic), black
• Function: pin/terminal fixation and insulation for enclosures
• Typical installation: control cabinets, starter assemblies, switchgear
• Mechanical properties: designed for secure retention of pins and terminals under normal industrial conditions

How to use

Fit the terminal block into the designated mounting points inside the enclosure or on the mounting rail according to the equipment manufacturer's instructions. Insert pins or terminals through the provided apertures and ensure they are seated and secured. Verify that the block aligns with the mating contactor or auxiliary component and that all fastenings are tightened to the recommended torque values for the associated hardware. Perform insulation and continuity checks after installation to confirm correct assembly.

What to consider before purchase

• Verify dimensional compatibility with your contactors, relays and enclosure mounting points
• Confirm that polyamide material properties meet your environmental and temperature requirements
• Ensure the block's mounting form factor fits the intended cabinet or starter assembly layout

Usage recommendations

Use this terminal block as a mechanical and insulating accessory within control cabinets and starter assemblies; combine it with appropriate fastening hardware and follow enclosure wiring standards. Regularly inspect mounted terminals for tightness and signs of wear or damage during maintenance intervals.
