6SY7010‑0AB66 Thyristor Block 1023 A 500‑575 V AC 3‑Phase

The Siemens 6SY7010‑0AB66 is a high‑current thyristor block designed for industrial infeed and regenerative feedback units. It features a snubber circuit (“layer A with snubber”) and is rated for 1023 A current and an AC voltage range of 500‑575 V for three‑phase systems at 50/60 Hz. Built for heavy‑duty applications, this module integrates into automation, drive and power conversion systems where robust semiconductors are required for rectification or switching in a hardened environment. The net weight is approx. 5.515 kg and the packaging dimensions are about 20 × 30 × 13 cm. This component is ideal where high current handling and durability are required, such as drive‑infeed units, motor drives, and industrial power systems.
