The contactor carries a mechanical endurance of 10 million operating cycles typical. The main contacts are configured as 16... 8 (likely NO/NC count). Switching frequency varies by duty: at AC-1 (resistive) it handles up to 1000 operations per hour, while AC-3 (motor starting) and AC-2 (slip-ring motor) are both rated at 750 ops/h. For AC-4 (plugging/inching) it drops to 250 ops/h — that's the number to check if your application involves frequent reversing or jogging. The auxiliary switch is included, rated at 24 V / 10 A through 230 V / 0.3 A for the contact side — enough for PLC input or relay coil feedback without an interposing relay in most 24 VDC control circuits.
Side clearance to adjacent devices is 6 mm; vertical (up/down/forward) clearance is 10 mm. Wire range: solid or stranded 1 … 10 mm² for main power connections, with a separate specification for auxiliary circuits: 2x (0.5 … 1.5 mm²) or 2x (0.75 … 2.5 mm²). The coil terminals are screw-type, so expect a screwdriver for termination — no spring-cage on this variant.
Environmental and electrical margins
Coil holding power is 0.25 VA at 50 Hz and 0.28 VA at 60 Hz — negligible for control transformer sizing. Operating time at AC is 4 … 16 ms; arcing time is 10 … 10 ms.
