Terminal block Rittal 9677.920 — rated voltage 690 V, width 98 mm

The Rittal 9677.920 terminal block is a compact connection component intended for professional electrical distribution systems. With a rated voltage of 690 V and a width of 98 mm, it provides secure connection points for conductors and helps maintain orderly wiring in switchgear, control panels and distribution assemblies. The design supports reliable electrical contact and mechanical stability for industrial environments.

Advantages

This terminal block offers stable electrical connections at up to 690 V and a standardized form factor with a 98 mm width to fit common mounting configurations. Its construction facilitates neat wiring runs and reduces the risk of loose or accidental disconnections. The component is designed for use in industrial switchgear and control cabinets where durability and predictable performance are required.

Suitable for

• Industrial switchgear and distribution panels
• Control cabinets and automation panels
• Professional electrical installations requiring secure conductor termination
• Applications where organized wiring and compact footprint are important

When it may not be suitable

This terminal block is intended for applications within its rated voltage and mechanical dimensions; it may not be suitable for low-voltage consumer electronics or for installations that require specialized connector types or integrated protection devices. Do not use it where a different width, voltage rating, or terminal style is specified by the system design.

Key specifications

• Rated voltage: 690 V
• Width: 98 mm
• Application: terminal block for conductor termination in switchgear and control panels
• Mounting: suitable for standard panel or rail mounting in distribution cabinets
• Electrical connection: designed for secure conductor connection and organized wiring

How to use

Mount the terminal block in the intended location in the switchgear or control cabinet according to the cabinet layout and mounting provisions. Prepare conductors to the appropriate strip length, insert conductors into the designated terminals and tighten connection screws or clamps to the manufacturer’s recommended torque values. Ensure correct phase identification and routing to maintain organized wiring and verify secure mechanical and electrical contact before energizing the system.

What to consider before purchase

• Confirm the terminal block width (98 mm) fits the available mounting space and panel layout
• Verify the rated voltage (690 V) matches system requirements
• Check conductor cross-section compatibility and required connection type
• Ensure mounting method is compatible with your cabinet or rail system

Usage recommendations

Follow applicable electrical standards and safety procedures during installation. Use recommended torque settings for terminal screws and verify insulation and phase marking after installation. For specific ambient, short-circuit or fault current considerations consult system design documentation or Rittal product guidance.
