The relay uses a thermal bimetallic release — no electronic settings, just a solid-state bimetal that tracks the motor's heating curve. IP20 on the front and terminals means it's safe for enclosed panel use; no washdown rating here, so keep it inside the cabinet. Mounting is contactor-mount only — it clips onto the front of a S00 contactor (like the 3RT1016 series). No DIN-rail option; the relay rides the contactor. Screw terminals on both main and auxiliary circuits accept 2x 0.5–2.5 mm² solid or stranded, torqued to 0.8–1.2 N·m. Depth is 78 mm, width 45 mm, height 87 mm — compact enough for dense panels. Side spacing to grounded parts is 6 mm minimum.","metaTitle":"Siemens 3RU7116-1BB0 SIRIUS Thermal Overload Relay, 2 A, CLA","metaDescription":"Siemens 3RU7116-1BB0 SIRIUS thermal overload relay, size S00, 2 A rated current, CLASS 10 trip, IP20, contactor mounting.

The 3RU2116-1FC1 has a different current range and trip class; verify your motor's FLA and starting profile before substituting. The 3RU7116-1BB0 is rated 2 A, CLASS 10; the 3RU2116-1FC1 covers a higher current band. Panel footprint and contactor-mount interface are the same S00, so it will physically fit without rewiring."},{"question":"How do I get current pricing and availability for 3RU7116-1BB0?","answer":"Submit an RFQ through the storefront.
