The 3RF3310-1AA04: The AC-1 rating (10 A at 40 °C) is the resistive load current the contactor can switch continuously. For motor loads or other inductive circuits, you'd need to derate based on the AC-3 or AC-4 duty cycle — the AC-1 figure alone doesn't cover that. The 48-460 V operating range covers common three-phase line voltages (up to 480 V nominal) and single-phase 230/400 V systems. The 24 V DC coil is standard for PLC-driven control panels, drawing a few hundred milliamps depending on the load.
Screw terminals accept standard wire sizes for control and power circuits. The package dimensions (97 x 27 x 105 mm) mean it fits a standard DIN-rail footprint with a 27 mm width — roughly 1.5 standard modular units. Mounting orientation and clearance for heat dissipation follow standard solid-state contactor practice; no forced cooling required at the rated 10 A AC-1 at 40 °C ambient.
