Grommet Rittal SZ 4311.000 — black, panel cable entry, protection IP 55 (accessory)

Rittal SZ 4311.000 is a black panel grommet designed to provide a sealed cable entry point in enclosures and control cabinets. Supplied as an accessory, this grommet enables routing of cables through panels while maintaining protection against dust and low-pressure water jets, meeting an IP 55 protection level. The product is intended for installation in distribution panels, industrial housings and electrical cabinets where a durable, compact cable pass-through is required.

Advantages

The grommet offers a compact, low-profile solution for cable entry that helps reduce ingress of dust and water at the panel interface. Its black finish provides a neutral appearance that integrates with most industrial enclosures. As an accessory designed for electrical cabinets and distribution panels, it simplifies cable routing and helps protect cable terminations from environmental exposure while preserving a neat installation footprint.

Suitable for

• Control cabinets and electrical enclosures requiring sealed cable entry
• Distribution panels and switchgear housings
• Industrial machines and housings with external cable routing
• Retrofitting or upgrading existing panels to improve ingress protection

When it may not be suitable

This grommet is designed for standard cable diameters and typical panel thicknesses; it may not be suitable for very large multi-core cable glands, conduit systems or non-standard enclosure cut-outs. It is intended to provide IP 55 level protection—if higher protection (for example IP 65, IP 66 or IP 67) or full strain relief is required, a different sealing solution or additional components should be considered.

Key specifications

• Color: black
• Function: sealed cable entry / grommet for panel mounting
• Protection rating: IP 55 (dust protected, protection against low-pressure water jets)
• Application: enclosures, control cabinets, distribution panels
• Form factor: compact, low-profile accessory for panel installation

How to use

Install the grommet into a suitable cut-out in the panel or enclosure wall according to the panel thickness and hole size recommended by the enclosure manufacturer. Route the cable through the grommet, ensuring the sealing lip engages around the cable to maintain the IP 55 protection. Secure the grommet in place as required by the enclosure design; verify that cables are not subject to excessive bending or mechanical stress at the entry point. After installation, check the seal visually and, if necessary, test the enclosure for ingress protection compliance under intended operating conditions.

What to consider before purchase

• Confirm the grommet dimensions and the required panel cut-out size match your enclosure.
• Verify the grommet provides adequate sealing for the cable diameters you plan to use.
• Assess whether IP 55 protection level meets environmental requirements for your installation.
• Ensure compatibility with the panel material and thickness where it will be mounted.

Usage recommendations

For best performance, use the grommet with cables that fit within the recommended diameter range and avoid sharp bends immediately at the entry point. For installations in harsher environments or where strain relief is necessary, combine the grommet with appropriate cable glands or additional sealing accessories.
