The Size S6 frame tells you the contactor's physical footprint and its current-carrying capacity in the SIRIUS family — it is the frame size that determines the main pole rating and the thermal capacity, not the coil voltage. The coil is rated 220-240 V AC at 50/60 Hz with an operating factor of 0.8 at both frequencies, meaning the coil holds in reliably down to 80 % of nominal voltage — important for brownout conditions on a production line. The spring-type terminals on the magnet coil eliminate the need for periodic re-torquing, a maintenance advantage in high-cycle applications. This contactor accepts stranded main circuit wiring from 16 to 70 mm², which covers the range from a 50 A feed to a 200 A motor circuit depending on the duty class. The auxiliary circuit accepts solid or stranded wire 2x 0.25-2.5 mm², typical for control wiring in a 24 VDC or 120 VAC pilot circuit. ## Duty-Class Switching Frequencies — AC-3 vs AC-4 Reality The maximum switching frequency varies sharply by duty class: 1 000 operations per hour in AC-3 (motor starting, normal running) and AC-3e, but only 130 operations per hour in AC-4 (plugging, inching, reversing). If your application requires frequent reversing or jogging, the AC-4 ceiling governs the contactor's thermal capability — exceeding it accelerates contact erosion and may cause welding. In AC-1 (resistive load) the limit is 800 ops/h, and in AC-2 (slip-ring motor starting) it drops to 400 ops/h. The arcing time is 10-15 ms, and the operating times are 40-60 ms for both AC and DC coil supplies — this gives a predictable contact closure window for sequencing logic. The mechanical life is 10 million operations typical, which is the contactor's service life before mechanical wear (spring fatigue, armature wear) — the electrical life will be lower and depends on the switched current and duty class. For a motor circuit running at rated current in AC-3, expect electrical life in the range of 1-2 million operations. ## Mounting and Clearance — Panel Layout Constraints Mounting is by screw fixing with a vertical mounting surface; the contactor can be rotated ±90° and tilted ±22.5° front-to-back. This flexibility helps when fitting into a crowded enclosure, but the clearance distances are fixed: 10 mm upwards, 10 mm downwards, 20 mm forwards, and 10 mm at the side. These are the minimum air gaps to adjacent metalwork or other devices — violating them risks flashover or restricted cooling. The dimensions are 172 mm height, 120 mm width, and 170 mm depth. The depth includes the coil terminals and arc chamber — allow the full 170 mm plus the forward clearance of 20 mm when positioning the contactor near the enclosure door or a busbar system. ## Auxiliary Contact Ratings and Temperature Range The auxiliary switch is rated for 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V (-). These are the make/break capacities for the control circuit — a 24 VDC PLC output driving a relay coil draws well under 1 A, so the 10 A rating at 24 V is generous for most signal circuits. The operating temperature range is -25 to +60 °C, suitable for most indoor industrial environments including non-conditioned panel rooms. Storage range is -55 to +80 °C, which covers shipping and warehouse conditions. The full-scale value of 1.1 indicates a 10 % overload capability — the contactor can carry 110 % of its rated current for short periods, useful during motor starting inrush. ## Lifecycle and Sourcing — Current Production, Quoted to Order Sourced through authorized distribution channels.
