S00 auxiliary contactor for SIRIUS contactors
The 3RH2140-1AP60: It occupies 45 mm width on the DIN rail, with 73 mm depth and 57.5 mm height, fitting standard panel layouts for S00 auxiliary modules.
What it switches and where it fits
This is an auxiliary contactor, not a main contactor. 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.
