The Siemens 3VM9111-0WD20 is a 2-pole terminal cover, a single-unit accessory designed for the 3VM11 series of molded case circuit breakers. It provides finger-safe shrouding over the line and load terminals after wiring, which is a standard requirement for panel builds needing IP2X touch protection at the termination point.
RoHS compliance is confirmed effective from October 1, 2014, and REACH Article 33 information is available on request for downstream reporting obligations.
Packaged as a single piece in dimensions 170 x 100 x 20 mm, the cover snaps onto the 3VM11 breaker body after wiring. No special tools are needed; the fit is specific to the 2-pole form factor of the 3VM11 frame.
