The Siemens SIRIUS 3RV2935-5E is a 3-phase supply terminal designed for the 3RV2 circuit breaker family, size S2. It's the type E (top-feed) variant, meaning power enters from above and distributes to the breaker's line side. This is the piece that connects your incoming feeder cables — solid or stranded — to the busbar system feeding the motor protection breaker. The screw-type terminals accept solid or stranded conductors: 2x (2.5 to 50 mm²) or 1x (2.5 to 70 mm²) per phase, with a separate reduced range for ferruled ends. That 70 mm² single-wire capacity is the one to watch — it lets you land a heavy feeder without paralleling smaller cables. Panel integration is straightforward: the terminal block is 55 mm wide, 66 mm tall, and 77 mm deep. That 77 mm depth is the critical dimension for enclosure depth planning — it's the projection from the DIN rail or mounting surface.

Frequently asked questions
What is the 3RV2935-5E's depth for panel layout?
The 3RV2935-5E has a depth of 77 mm, which is the projection from the mounting surface into the enclosure. This is the dimension to check when planning gland plate clearance and enclosure depth.
What wire sizes does the 3RV2935-5E accept?
The screw terminals accept solid or stranded conductors: 2x (2.5 to 50 mm²) or 1x (2.5 to 70 mm²) per phase. For ferruled ends, the range is 2x (2.5 to 35 mm²) or 1x (2.5 to 50 mm²). AWG equivalents are 2x (10 to 1/0) or 1x (10 to 2/0).
