For resistive loads (AC-1), the operating current maxes at 10 A. The coil includes a full-wave rectified surge suppressor built in — no external snubber needed on the coil circuit. The 4 kW at 690 V AC-3 rating is the headline number for motor switching — it tells you this contactor can start and stop a 4 kW induction motor on a 690 V line. But the real-world selection parameter is often the AC-3 current at the system voltage you actually run. At 400 V, the AC-3 rating is 3 kW, which corresponds to roughly a 7 A motor full-load current — a common size for small pumps, fans, and conveyors. The AC-4 rating of 6.5 A at 400 V is the one to check if the contactor sees frequent plugging or jogging duty; that current is lower than the AC-3 value because the contacts have to break locked-rotor current. The auxiliary contact block is a single instantaneous contact (1 NO or 1 NC depending on wiring). If your circuit needs more auxiliary contacts for status feedback or interlocking, you'll need to add a side-mount auxiliary contact block — the S00 frame accepts the standard Siemens auxiliary blocks. The S00 frame is 45 mm wide, 60 mm tall, and 114 mm deep, so it fits in a standard 45 mm slot on a DIN rail. Wire sizing: the spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG) for the main contacts. The coil operates at 50/60 Hz with a voltage tolerance of 0.8 to 1.1 times rated at 50 Hz and 0.85 to 1.1 at 60 Hz — so a 110 V coil will pick up reliably down to about 88 V at 50 Hz.","metaTitle":"Siemens 3RT1015-2GG28-0NA4 SIRIUS Power Contactor, S00, 4 kW","metaDescription":"Siemens SIRIUS power contactor 3RT1015-2GG28-0NA4, size S00, 4 kW at 690 V AC-3.
