Description
The Siemens 3RV1021-1AA10 is a SIRIUS series motor circuit protector engineered to defend industrial motors against overloads. It features an adjustable thermal setting from 1.1 to 1.6 amps and utilizes a rotary handle mechanism that offers clear trip indication. Constructed in the S0 frame size, this protector installs easily onto 35mm DIN rails inside motor control centers. While replaced by the S00-sized 3RV2011-1AA10, this original S0 unit serves as an exact replacement.Specifications
