It is rated for AC-1 utilisation category at 25 A, with a rated operational voltage up to 415 V and a 230 V coil. This makes it suited for switching resistive loads — heaters, lighting banks, or other non-inductive circuits — where the current is in phase with voltage and there is no motor inrush or inductive kick.
AC-1 is a lower-stress duty than AC-3 (motor starting), so if your application involves motor loads, this contactor is not the right fit — you would need a part rated in AC-3. The 4NO pole configuration gives four independent switching paths, all closing together on coil energisation. Dimensions are 45 mm width, 74 mm height, and 80 mm depth.
These are the core standards for low-voltage switchgear and controlgear — part 4-1 covers contactors and motor-starters, part 5-1 covers control-circuit devices. Operating altitude is rated to 3000 m without derating.
