It is rated for AC-1 utilisation category (resistive loads) at 40 A up to 415 V, making it a fit for switching resistive heating elements, lighting banks, or other non-inductive loads in a panel.
The Easy TeSys Control range has been superseded by newer contactor families (e.g., TeSys Deca or TeSys GV2). If you are replacing this part in a legacy panel, verify the mounting footprint and coil voltage before specifying a substitute — the 45 mm width and DIN-rail profile are common, but the control circuit rating and auxiliary configuration must match.
For motor loads (AC-3 duty), the rating would be lower — this part is not intended for inductive motor starting unless derated. The 4-pole arrangement with 2NO+2NC gives flexibility for switching two independent circuits or providing a normally-closed interlock. Operates in ambient temperatures from -20 °C to 70 °C at the coil rating, with storage from -60 °C to 80 °C. The 1.5 ms non-overlap time between NC and NO contacts (both on energisation and de-energisation) ensures that break-before-make is maintained — critical for interlocking circuits where overlapping contacts could cause a short.
