The BC7-40-00-01 is a 4-pole contactor rated AC1-16A with a 24 VDC coil. The AC1 rating means it's sized for resistive loads — heaters, lighting banks, non-inductive circuits — up to 16 A per pole. For motor duty (AC-3), you'd need to derate; the listing doesn't carry that number, so verify against your load type.
The 16 A AC-1 rating governs resistive switching. If your load is a resistive heater bank, this contactor handles it. If it's a motor, a transformer, or any inductive load, the AC-3 or AC-4 rating would be the real selection figure — and it's not on the record here. The 24 VDC coil is standard for PLC or relay logic control; verify the coil pickup and dropout voltage against your supply, especially if the control voltage sags under load.
Four-pole contactor, DIN-rail mount. It switches three phases plus a neutral or a fourth load circuit. The 24 VDC coil keeps it compatible with modern PLC outputs or solid-state relay drivers. Spring-cage or screw terminals — the listing doesn't specify, so check the physical sample or datasheet before panel layout.
