The front is IP20 — touch-safe for the operator side — but the relay itself is not sealed against washdown; keep it inside a cabinet. At 45 mm wide, three of these side-by-side consume 135 mm of DIN rail — plan your gutter space accordingly. Main and auxiliary circuits use screw-type terminals. The main contacts accept 1× 20–16 AWG, 1× 18–14 AWG, or 1× 12 AWG solid/stranded. Auxiliary contacts accept 2× 20–16 AWG or 2× 18–14 AWG. For finely stranded wire with ferrules, the range is 2× (0.5–1.5 mm²) and 2× (0.75–2.5 mm²). The auxiliary contact ratings cover the common control voltages: 1 A at 24 V, 3 A at 120 V, 2 A at 230 V, and 1 A at 400 V AC. At 110 V and 125 V the contact is rated 0.22 A — likely a DC rating for those voltages, so verify the load type before wiring a DC solenoid or contactor coil through it. This relay lives in the SIRIUS S00 family, the smallest frame size. It carries ATEX approval (DMT 98 ATEX G 001).","metaTitle":"Siemens 3RU1116-1FB1 SIRIUS Thermal Overload Relay, Size S00","metaDescription":"Siemens 3RU1116-1FB1 SIRIUS thermal overload relay, Size S00, Class 10 trip, 45 mm wide, ATEX approved, IP20 front.
