Siemens 3RV2011-1AA25 is a three‑pole molded‑case motor protection circuit breaker (MPCB) from the Sirius 3RV2 family, designed for S00 frame installations to protect small motors and drives. It is rated for up to 400 V AC and provides a thermal‑magnetic trip with an A‑release setting around 1.1–1.6 A, offering a 100 kA short‑circuit breaking capacity for reliable panel protection. The device includes an integrated auxiliary contact arrangement of 1 NO + 1 NC for signaling and control, and it uses spring‑type terminals for secure connections. Typical applications include motor protection in machine tools, pumps, conveyors, and fans, where compact, multi‑pole protection is required in automation equipment.
