Product Overview
The Siemens SIRIUS 3RB3016-1TB0 is an electronic overload relay designed to protect three-phase motors against overload and phase failure conditions. It monitors motor current and helps protect connected equipment by triggering a trip when an overload or phase disturbance is detected.
Designed for mounting onto compatible S00 contactors, this relay features screw terminals for the main and auxiliary circuits, manual or automatic reset functionality, and a trip indicator. It is suitable for industrial motor control panels and compatible marine electrical installations.
