It is rated for 50 A at up to 415 V, and carries a 240 V coil. The part mounts on either a plate or a DIN rail, fitting into standard panel layouts with a 56 mm width and 93 mm depth.
The AC-1 rating of 50 A at ≤415 V governs its use: this contactor is intended for resistive loads like heaters or lighting banks, not for motor starting (which would require an AC-3 rating). The 4NO pole configuration means all four poles are normally-open, so it switches four independent resistive circuits or one three-phase resistive load plus a neutral. The coil voltage is 240 V — verify your control circuit voltage matches before specifying. Operating altitude is rated to 3000 m. Mechanical robustness is specified: vibrations at 1.5 Gn (contactor open) and 3 Gn (closed) over 5–300 Hz, and shocks at 6 Gn open / 10 Gn closed for 11 ms.
