The Siemens 3RU1116-0BB0 is a SIRIUS thermal overload relay in size S00, with CLASS 10 trip characteristic. It mounts directly to a contactor and uses screw-type terminals on main and auxiliary circuits.
Clearance and mounting flexibility
Zero clearance required upwards, forwards, backwards, and downwards — the relay can be stacked tight against adjacent devices on the DIN rail or panel. Only 6 mm side clearance is needed. The mounting position allows rotation up to ±135° and tilting up to ±45° from vertical, which helps when routing cables in a crowded enclosure. IP20 on the front means basic finger protection; the relay is not rated for washdown environments.
Environmental and compliance data
The relay withstands 100 % relative humidity during operation. Shock resistance is rated at 8g for 10 ms.
