Siemens 8WH9000-1VA00 Two-Tier Terminal Block Cover

Siemens 8WH9000-1VA00 is a gray end cover for two-tier terminal blocks in the 8WH family, designed for blocks with a spring-loaded terminal and a conductor cross-section of 2.5 mm². This lightweight cover weighs about 3 g and features a nominal material thickness of 2.2 mm, delivering a compact finish at the end of a DIN-rail terminal block stack. The gray enclosure is rated UL 94 V0 for flame resistance and includes no latching mechanism, aligning with standard end-cover specifications for 8WH two-tier configurations. As an official Siemens accessory, the 8WH9000-1VA00 covers two-tier terminals with spring-loaded termination and is documented in Siemens data sheets and LV10 catalogs as a gray end cover plate (no intermediate plate) for 8WH blocks, with a width specification of 2.2 mm. This part is commonly used to close the outer ends of 8WH two-tier assemblies in industrial control panels, providing physical protection for conductors while preserving access for wiring and test points and ensuring consistent compatibility within Siemens low-voltage installations.
