The Siemens 3RT2936-1BC00 is a SIRIUS varistor-type surge suppressor designed to clip directly onto 3RT2.3 (S2) and 3RT2.4 (S3) contactors, suppressing voltage spikes across the coil at the source.
At 30 mm wide, 30 mm tall, and only 15 mm deep, it adds negligible footprint to the contactor assembly and clips on without tools.
This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
It clips onto SIRIUS contactors in sizes S2 (3RT2.3) and S3 (3RT2.4).
The part meets RoHS with a substance prohibition date of October 1, 2014.
