What this kit does
The Siemens 3VA9877-0CB10 is an operator kit with a Bowden cable for the Max-Flex operator switching mechanism. It is a single accessory designed for use with 3VA57, 3VA58, 3VA59, 3VA67, 3VA68, and 3VA69 molded case circuit breakers. This kit allows remote or panel-door mounting of the rotary operating mechanism, with the Bowden cable transmitting the mechanical motion from the door handle to the breaker's switching mechanism. It is a field-installable accessory, not a standalone breaker.
RoHS compliance is confirmed since February 17, 2021. REACH Article 33 information is available per the current candidate list.
What fits where
The kit is a single accessory — one piece per package. Packaging dimensions are 297 x 241 x 97 mm, which gives you a sense of the box size for panel integration planning. It is classified as Product Class B: return restricted, meaning direct returns to Siemens require prior contact through your Siemens partner. This is standard for installed accessories and does not affect normal procurement.
