The 24 VDC coil with spring-type terminals means no screw torque to verify — strip, insert, release. The 45 mm width and 73 mm depth fit standard DIN-rail enclosures; mounting is screw or snap-on onto 35 mm rail per DIN EN 60715. The AC-3 maximum switching frequency of 750 cycles per hour tells you it handles moderate-duty motor starts without overheating, while the AC-4 maximum of 250 cycles per hour covers plugging or inching duty where the contactor makes and breaks locked-rotor current. Mechanical life is typical 30 million operations, so it outlasts most machines it controls.
Mounting and wiring — the practical fit
The spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², and you can double up two conductors of the same cross-section in one clamp. The contactor can be mounted in any orientation within ±180° rotation on a vertical surface, and tilted forward or backward up to ±22.5° — useful when the panel layout is tight. Arcing time runs 10 to 15 ms at AC, so plan for that in your coordination study.
