Panel fit and wiring constraints
The 3RT2325-2AC20-1AA0: The S0 frame measures 60 mm wide by 102 mm high by 97 mm deep, so it occupies a standard 60 mm DIN-rail slot with room for side-by-side contactors at 6 mm clearance between units. Mounting position is standing on a horizontal surface; clearance of 10 mm upwards, downwards, and forwards, plus 6 mm at the side, keeps arc flash and heat dissipation within the enclosure envelope.
Coil voltage and switching duty
Mechanical service life is 10 million cycles typical, so the contactor outlasts most panel designs in cyclic conveyor or pump-start applications.
