Rittal 9666190 SV 9666.190 - 1 WU / 4 U, Lead-Seal Ready

The SV 9666.190 provides a compact 1 WU (250 mm) width and 4 U height footprint, enabling a scalable core for panel layouts. This space efficiency translates into higher component density without sacrificing clearance for wiring and testing, reducing panel depth and allowing more flexible terminal block arrangements. It is ideal for cabinets housing terminal blocks, switchgear, and other mounting hardware in distributed automation setups. With four 35/15 mm support rails included, the module supports dense block configurations and multi-row wiring. The 25 mm pitch-adjustable design makes alignment straightforward during panel assembly, minimizing field trimming and rework. This reduces installation time and ensures consistent spacing across multiple enclosures in a line. The cover is made from polystyrene and is lead-seal prepared, delivering tamper-evident security for restricted-access cabinets. Combined with a zinc-plated sheet steel support rail, the unit resists corrosion and mechanical wear in harsh environments. These features help maintain compliance with internal control standards and external audits. The color, RAL 7035, ensures uniform appearance across devices, making it easier to match existing enclosures and reduce repainting costs during upgrades. Supplied as 1 pack with assembly parts, it simplifies procurement and reduces sourcing complexity for procurement teams. The 250 mm width and 600 mm height, with a total weight of approximately 2.1 kg per pack, enable straightforward handling and installation. Compatibility with 25 mm pitch and standard 35/15 rails makes it straightforward to retrofit into existing installations and to pair with common terminal blocks and switchgear brands.
