Electrical enclosure cover plate Rittal 9677.402 — white polyamide, rear connection compartment cover

Rittal 9677.402 is a white polyamide cover plate designed for rear connection compartments of electrical enclosures. The cover provides a durable, non-conductive closure for access points in switchgear and cabinets, helping to protect wiring and isolate connection areas. Lightweight and compact, the cover is intended to fit behind connection zones and offers mechanical protection as well as improved safety for terminal connections.

Advantages

The polyamide construction ensures electrical insulation, impact resistance and dimensional stability in a range of ambient conditions. As a purpose-made rear connection compartment cover, it simplifies installation by providing a ready-to-fit protective barrier that reduces the risk of accidental contact with live parts. Its light weight means it adds minimal load to the cabinet while still offering reliable protection for ring terminals and long press sleeves.

Suitable for (tasks / use cases)

• Covering rear cable connection compartments in industrial and commercial switchgear
• Protecting wiring and terminals where ring terminals with long press sleeves are used
• Isolating live parts to help meet site safety and equipment protection requirements
• Use in control panels, distribution cabinets and electrical enclosures requiring a rear-side access cover

When it may not be suitable

This cover is intended for use as a non-conductive compartment closure and not as a primary load-bearing panel or external weather seal. It is not suitable where specific IP-rated external sealing or mechanical reinforcement is required unless additional gaskets or supports are used. For enclosures that require specialized flame-retardant materials beyond standard polyamide, a different specification should be selected.

Key specifications

• Material: polyamide (white)
• Application: rear connection compartment cover for electrical enclosures
• Weight: approximately 85 g
• Function: non-conductive protection and isolation of wiring and terminal areas

How to use

Fit the cover plate to the rear connection compartment according to the enclosure manufacturer’s mounting points. Ensure wiring and ring terminals are positioned correctly and that long press sleeves are contained behind the cover to provide contact hazard protection. Verify the cover is securely seated and any mounting screws or clips are tightened to prevent displacement. Check clearance from live parts and confirm that the installed cover does not interfere with cable routing or ventilation requirements.

What to consider before purchase

• Ensure compatibility with the enclosure model and mounting points for rear connection compartments
• Confirm that polyamide material properties meet site requirements for insulation and mechanical resistance
• Assess whether additional sealing, reinforcement or flame-retardant specification is needed for your application

Usage recommendations

Use the cover to maintain safer rear-side cable management: position ring terminals and long press sleeves fully behind the plate, secure the plate according to the enclosure instructions, and inspect periodically for mechanical wear or deformation to ensure ongoing protection.
