The Siemens 3RU7116-0FB0 is a SIRIUS thermal overload relay in size S00 with CLASS 10 trip. Rated operational current is 0.5 A, maximum operating voltage 690 V AC/DC across three poles. It mounts directly to a Siemens S00 contactor.
Fastens directly onto the contactor — no separate DIN-rail footprint. The relay is 78 mm deep, 45 mm wide, and 87 mm tall. For grounded parts alongside, leave 6 mm clearance.
Depth is 78 mm, width is 45 mm, height is 87 mm.
It is CLASS 10, meaning it trips within 10 seconds at 7.2× the rated current.
