The Siemens 3VA9503-0SB50 is a cover frame that trims the door cutout for a front-mounted rotary operator with door interlock on 3VA15, 3VA25, and 3VA26 IEC circuit breakers. The cutout measures 200.3 x 200.8 mm (WxH) — that's the opening you punch in the enclosure door, and this frame covers the gap around the operator handle. It belongs to the 3VA9 accessories family, which supports breakers up to 1250 A. If you're panel-building with those frames, this is the trim piece that keeps the door cutout clean and meets the IP rating of the enclosure.
Export control is straightforward: AL N / ECCN EAR99, no special license required for most destinations. Product class B means return is restricted — contact your Siemens partner for RMA terms.
What's in the box
Supplied as one piece, packaged in a 300 x 200 x 10 mm carton. That's a slim envelope — easy to bin alongside the breaker it mates to.
