It carries a 3-pole power pole with 3 NO contacts and one NC auxiliary. The AC-3 rating is 16 A at ≤440 V, which means it can switch a 3-phase induction motor up to that current in the forward/reverse direction — the rating that governs real motor-reversing duty on pumps, conveyors, or small compressors. The coil is 110 V AC 50/60 Hz.
The AC-3 utilisation category covers starting and plugging of squirrel-cage motors — the dominant load for this class. AC-4 (also listed) covers inching and plugging duty, which is harder on contacts; the same 16 A applies but expect reduced electrical life under frequent reversals. The IP20 finger-safe terminals suit enclosed panel mounting — no additional touch protection needed inside the cabinet. Operating altitude is 2000 m without derating, so standard installations at most industrial sites are fine; above that, consult the thermal derating curve.
Integration notes
Dimensions are 90 mm wide by 58 mm high by 57 mm deep — it occupies a standard 90 mm-wide DIN-rail footprint. The reversing busbar is preassembled, so no separate wiring between the two contactor halves; just land the motor leads and coil supply. The 1 NC auxiliary is wired for electrical interlocking to prevent both contactors closing simultaneously. Flame retardance meets V1 per UL 94 and NF F 16-101/102, which is typical for rail and transit applications.
