The Siemens 3VU2935-0D is a front-side extension connector designed for use with the 3VU2.4 and 3VU2.5 series of motor protective circuit breakers. It extends the connection point to the front of the device, simplifying wiring access in tight panel layouts.
This connector mounts directly onto the front of the 3VU2.4 or 3VU2.5 breaker, providing an additional terminal point for outgoing wiring without increasing the DIN-rail footprint. It is a mechanical accessory — no electrical ratings or approvals apply beyond those of the host breaker.
