Trip Class 10 gives you a 10-second trip window at 7.2× rated current — standard for general-purpose motor starting where the load isn't a high-inertia fan or flywheel that needs a slower class. The 0.35–0.50 A adjustment window is the one number that decides whether this relay fits your motor nameplate. If your motor FLA falls inside that band, you're good — set it to the FLA and the thermal bimetal tracks the heating curve. Outside it, you need the next size up or down in the 3RU6 family. The 4.2 W typical power loss and 4.8 W at rated current in hot state matter for enclosure heat buildup — in a sealed panel with several relays, that wattage adds up; the 6 mm side spacing requirement is the minimum clearance to keep heat from neighbouring devices from shifting the trip point. Stand-alone installation — no DIN rail adapter needed, though it can also clip onto the SIRIUS contactor. Mounting position is any, which helps in tight enclosures. The 80 mm depth, 45 mm width, and 89 mm height define the panel footprint: it's a compact block that fits a standard 45 mm-wide DIN slot. Wire range accepts 2× 0.5–1.5 mm² solid or 2× 0.75–2.5 mm² stranded, with AWG equivalents 2× 20–16 and 2× 12 for the main circuit. Humidity tolerance 0–90%. Installation altitude max 2,000 m. Surge voltage resistance 6 kV. Shock resistance 8g / 11 ms per IEC 60068-2-27. RoHS compliance date 05/01/2012 — the part is RoHS-compliant; REACH and UL documentation is standard with the SIRIUS line.","metaTitle":"Siemens 3RU6116-0FB1 SIRIUS Thermal Overload Relay, 0.35-0.5","metaDescription":"Siemens 3RU6116-0FB1 SIRIUS thermal overload relay, adjustable 0.35-0.50 A, Trip Class 10, Size S00.
