The AC-3 switching frequency is rated at 1,000 operations per hour maximum, which covers most conveyor and pump cycling without derating. AC-4 drops to 300 ops/h — that's the inching or plugging duty limit, so if your application reverses the motor under load, stay under that ceiling. The mechanical life is a typical 10,000,000 operations, meaning the contactor itself outlasts most panel refreshes. For DC switching, the contactor is rated at 6 A at 24 V, 2 A at 48 V, and 1 A at 110 V. These are resistive load figures; inductive DC loads need a diode or RC snubber across the coil to avoid contact erosion. The coil pickup is guaranteed at 80% of rated voltage (88 V for this 110 V coil), and withstands 110% continuously — so it holds in during brownout conditions down to about 88 V. Wire range accepts 1 to 10 mm² solid or stranded on the main contacts, and 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) fine-stranded for auxiliaries. That covers most panel wiring up to 6 AWG.
That flexibility helps when the panel layout is tight. The 85 mm height and 151 mm depth mean it fits in shallow enclosures.
