SENTRON
3VA Accessories – 3VA9221-0WG40
The Siemens 3VA9221-0WG40 is a terminal cover
(4-pole extended/broadened type) designed for SENTRON 3VA2 molded case
circuit breakers (MCCB). It is used to provide safe insulation and
protection of power terminals, ensuring that all live parts are fully
covered after installation.
This accessory improves operator safety, installation
compliance, and panel protection by preventing accidental contact with live
terminals and reducing risks such as short circuits, dust ingress, and wiring
damage. The extended design makes it suitable for 4-pole MCCB configurations
(3-phase + neutral systems).
The 3VA9221-0WG40 is widely used in LT
panels, MCCs, PCCs, industrial switchboards, and OEM electrical panels,
where safety, reliability, and standardized installation are required.
