It provides Class 10 motor protection with a rated operational current of 0.25 A at 690 V AC/DC, 50/60 Hz. The relay uses a bimetallic thermal release mechanism and is rated for 3-pole main circuits with screw-type terminals. Class 10 trip means the relay must open within 10 seconds at 7.2× the set current — fast enough for standard motor start profiles on pumps, fans, and compressors where the start time stays under 10 seconds. The 0.25 A rating covers small motors (roughly 0.06 kW at 400 V). For comparison, the 3RT1016-1AR11 contactor is a common mate in the same S00 frame, sharing the same mounting footprint and terminal spacing — no rewiring needed to swap the overload relay on an existing panel. Mounts directly onto S00 contactors via the contactor mounting fastening method. Side spacing to grounded parts is 6 mm minimum. Screw terminals accept 2× (0.5…1.5 mm²) solid/stranded or 2× (0.75…2.5 mm²) with ferrules; torque to 0.8…1.2 N·m.","metaTitle":"Siemens 3RU7116-0CB0 SIRIUS Thermal Overload Relay, Class 10","metaDescription":"Siemens 3RU7116-0CB0 SIRIUS thermal overload relay, Class 10 trip, rated 0.25 A, 690 V, size S00, IP20.
