Its rated operational current is 5 A, and it is a Class 10 trip device — meaning it will trip within 10 seconds at 7.2× the current setting, which is the standard protection for standard-start induction motors that are not high-inertia loads. The relay mounts directly onto a contactor of the same S00 frame size, with a vertical mounting surface that is rotatable ±135° and tiltable ±45° front-to-back, giving panel builders flexibility in orientation. Screw-type terminals are used for both the main and auxiliary circuits. ## Integration notes At 45 mm wide, 87 mm tall, and 78 mm deep, the S00 footprint fits standard DIN-rail panels, but note the required 6 mm spacing to grounded parts on the side. The total typical power loss is 6.6 W at rated current, so account for that in the enclosure thermal budget. Wire termination accepts 2× (0.5 to 1.5 mm²) solid or stranded, or 2× (0.75 to 2.5 mm²), with a torque range of 0.8 to 1.2 N·m for the main and auxiliary screw terminals.","metaTitle":"Siemens 3RU7116-1FB0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens SIRIUS 3RU7116-1FB0 thermal overload relay, size S00, rated 5 A, trip class 10.
