The coil is rated 110 V AC and includes an integrated varistor surge suppressor, so you don't need to add a separate suppression module across the coil — one less part to wire and one less failure point to chase. Main power connections are screw-type terminals, accepting up to 2x 10 mm² or 1x 8 AWG stranded. The auxiliary and coil terminals take 2x (0.25...2.5 mm²) solid or 2x (1...2.5 mm²) stranded.
The motor power ratings tell the real story: 7.5 kW at both 500 V and 690 V AC-3 duty. That means it switches a standard three-phase induction motor up to 7.5 kW on a 400 V or 690 V line — the AC-3 rating governs the load-break capability for starting and stopping a running motor, not just holding it closed. For heavy plugging or inching duty (AC-4), the contactor is rated 12.5 A at 400 V. The resistive-load rating (AC-12) maxes out at 10 A operating current — useful for switching heater banks or other non-inductive loads where the contactor sees no motor inrush. Short-circuit coordination matters for panel protection: with Type 2 coordination (limited damage to the contactor after a fault), the maximum fuse is gL/gG 25 A. Pick your fuse size based on which coordination level your panel design requires. Electrical life will be lower and depends on the switched current and duty cycle.
Where it goes and what it tolerates
That means it is suited for industrial control panels in factory environments, not for clean-room or sealed-cabinet use without derating. The front face carries IP20 finger protection — safe for panel installation where the front is accessible. The terminal area itself is IP00, meaning the wiring compartment is not touch-safe; that is normal for a panel-mounted contactor where the enclosure provides the overall protection. Side-by-side mounting is allowed without derating, which saves panel width when ganging multiple contactors.
Because it is an active Siemens SIRIUS part, the compliance documentation you would expect is available: the manufacturer provides RoHS, REACH, and CE declarations, plus UL/CSA recognition through the SIRIUS product family certification. The varistor surge suppressor is built in, so the contactor meets the relevant IEC 60947-4-1 standards for motor starters.
