It is rated for AC-1 utilisation category at 20 A with a coil voltage of 48 V, making it suited for switching resistive loads in control panels up to 415 V. It carries IP2X finger protection per IEC 60529, so it is intended for enclosed installation where accidental contact is prevented by the cabinet door.
What the AC-1 rating means for fit
The AC-1 rating of 20 A at ≤415 V is the thermal current rating for resistive loads — heaters, incandescent lighting, or resistive banks. This is not a motor-switching rating (AC-3); if your application involves inductive motor loads, this contactor's AC-3 rating would be lower, and the part may not be the correct fit. The 4-pole configuration with 2NO+2NC gives flexibility for interlocking or dual-load switching within a single device.
