Product details

Star-delta starter in S00 frame — what fits in the panel

The 3RA2415-8XF31-2AP0 is a Siemens SIRIUS contactor assembly for star-delta (wye-delta) motor starting, built around three 3RT2015-2AP01 contactors in the S00 frame size.

Power ratings and what they mean for the motor load

Mechanical life is 10 million operating cycles typical, which suits frequent-start applications like conveyors or pumps where the starter cycles multiple times per hour.

It ships with the RS assembly kit 3RA2913-2BB2 included, and the three contactors are pre-configured for star-delta wiring — no separate contactor ordering or inter-wiring is needed.

Frequently asked questions

What is 3RA2415-8XF31-2AP0's listed depth?

The depth is 145 mm, with a width of 135 mm and height of 84 mm, fitting the S00 contactor frame footprint.

What compliance documentation does Siemens provide for 3RA2415-8XF31-2AP0?

No additional UL or IEC certs are listed in the spec record, but as a SIRIUS series component it is designed to IEC 60947-4-1 standards.
