The Siemens 3VM9211-0WJ30 is an extended 3-pole insulating plate, a 1-unit accessory designed specifically for the 3VM12 molded case circuit breaker family. It provides the physical barrier between phases or between the breaker and adjacent panel components, maintaining clearance and creepage distances per the breaker's ratings.
RoHS compliant since 01-10-14, with REACH Article 33 information available on the current candidate list. Product class B means return is restricted — contact your Siemens partner for any return authorization.
Physical fit
Packaged dimensions 150 x 120 x 30 mm, one piece per unit. The plate mounts as a bolt-on accessory to the 3VM12 breaker; no DIN-rail footprint change — it adds depth behind the breaker face.
