Rittal SV 9674.790 Roof Plate Pressure Stopper - IP 54

Pressure relief for IP55 roof plates provides a built-in venting path when the enclosure experiences pressure differentials, enabling arc-proofing and safer operation in fault conditions. The SV 9674.790 converts an IP55 roof plate to a protected IP54 surface, reducing the risk of seal leakage and permitting safer maintenance access. This retrofit is purpose-built for Rittal enclosures and integrates with existing roof plate configurations to minimize retrofit time and risk while maximizing safety. Polyamide is used as the construction material, delivering low moisture uptake, good electrical insulation, and robust mechanical performance in factory environments. The lightweight material also simplifies handling during installation and reduces wear on mounting components, contributing to lower maintenance costs over the enclosure's life. Compatibility with standard roof-plate fasteners helps ensure a straightforward retrofit, even in crowded electrical rooms. Each order ships with four warning stickers, supporting clear safety messaging during operation and servicing. The note indicates that two pressure stoppers and one warning sticker are required per roof plate, which helps planning and inventory control for procurement teams. Having pre-packaged components accelerates installation, reduces the risk of missing items, and improves compliance with on-site safety procedures. Pack size and weight support efficient logistics: four units per pack, with a weight of 0.08 kg per pack, enabling easy stacking with other enclosure accessories. The compact form factor simplifies warehouse storage and reduces transport costs, particularly for large-scale retrofit projects across multiple cabinets. From a standards and classification perspective, the product aligns with ETIM EC000032 (ETIM 9/ETIM 8) and ECLASS 8.0 23110190, supporting accurate cataloging and procurement data. The pressure stopper also supports IEC/TR 61 641 arc-proofing compliance and delivers IP54 after retrofit, allowing installers to meet regulatory requirements without compromising enclosure integrity.
