The Size S00 frame (45 mm wide, 58 mm tall, 73 mm deep) is the smallest SIRIUS contactor footprint — it packs into tight DIN-rail layouts where panel space is at a premium. The 24 V DC coil is standard for PLC-driven control circuits; at 24 V rated value the auxiliary switch handles 10 A, enough for pilot duty on most small motor starters. Wire range accepts 0.5 to 4 mm² solid or stranded, and up to 2x 4 mm² in the same terminal — common for control wiring in North American and European panels. The screw-type coil terminals are field-proven; no special tooling needed. Switching frequency varies by duty: 1 000 cycles/hour at AC-1 (resistive), 750 at AC-2 and AC-3 (motor starting/running), and 250 at AC-4 (plugging/inching). For a conveyor or pump running AC-3 duty, that's 750 operations per hour — match this to your cycle rate before committing the BOM line. Mechanical life is typical 30 000 000 operations — the contactor will outlast most panel rebuilds. Operating temperature range is -25 to +60 °C, storage -55 to +80 °C, so it's fine for unheated plant floors in temperate climates. Mounting position is flexible: +/-180° rotation on a vertical surface, and can be tilted forward/backward by +/-22.5°. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side — tight enough for dense panel layouts but check against adjacent heat-generating devices.","metaTitle":"Siemens SIRIUS 3RT2018-1AP01-ZW97 Power Contactor, Size S00,","metaDescription":"Siemens SIRIUS 3RT2018-1AP01-ZW97 Size S00 power contactor, 24 VDC coil, 45 mm wide, screw terminals, snap-on DIN rail.
