It provides 4 instantaneous NO contacts for signaling, interlocking, or control circuits in motor starter groups or PLC output isolation. ## Mounting and wiring clearances Minimum clearances: 10 mm upwards/downwards/forwards, 6 mm to the side. These ensure adequate arc quenching and cooling in polluted environments (degree of pollution 3). Terminals accept solid or stranded wires: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm². Use ferrules on stranded conductors for reliable spring-cage connection. Rated at 50/60 Hz with a tolerance band of 0.8–1.1 at 50 Hz and 0.85–1.1 at 60 Hz.","metaTitle":"Siemens 3RH2140-1AP60 SIRIUS Aux Contactor, 4 NO, S00","metaDescription":"Active SIRIUS auxiliary contactor, 4 NO contacts, size S00, 45x73x57.5 mm, screw and snap-on DIN rail mount.
