It's a DOL (direct-on-line) starter for small three-phase motors up to 0.1 kW at 400 V AC-3 duty, with a setting range of 0.28 to 0.4 A. That's the whole point of a compact starter: put the motor control right at the load, not back in a cabinet. It communicates over AS-interface (AS-i), the two-wire bus that carries both power and data on a single flat cable. The part has two integrated inputs for sensors (e.g., limit switches or presence detectors) and a motor brake output rated for 500 V DC / 1 A, so it can handle a DC brake coil directly without an external relay. The 0.1 kW AC-3 rating at 400 V tells you this is sized for very small motors — think fractional-horsepower drives on small conveyors, agitators, or positioning slides. The 0.28 to 0.4 A setting range on the bimetal overload matches the full-load current of those motors. Don't try to stretch it beyond 0.4 A; the bimetal element won't trip correctly above that. The 50,000 A short-circuit breaking capacity (Icu) at 400 V is a standout for a starter this small. That rating is the SCCR for the whole assembly, not just the contactor. The -25 to +55 °C operating temperature range covers most factory-floor conditions, including unheated warehouses in winter. The DC voltage type on the control side means it expects 24 V DC nominal from the AS-i bus — no AC coil to worry about. This is a field-mounted unit, not a panel-mount device. The two integrated inputs let you wire local sensors back through the AS-i bus without a separate I/O block. The dimensions — 270 mm high, 120 mm wide, 190 mm deep — are the envelope for the complete starter housing. It's not a DIN-rail component; it bolts to a mounting plate or machine frame via its own footprint. Plan for clearance around the cable entries and the AS-i flat cable routing.","metaTitle":"Siemens 3RK1322-0ES02-0AA4 AS-i Compact Starter, 0.28-0.4 A,","metaDescription":"Siemens SIRIUS 3RK1322-0ES02-0AA4 AS-i compact direct starter, 0.1 kW at 400 V AC-3, 0.28-0.4 A setting range, IP65, with brake contact and 2 integrated inputs.
