The 3RT1456-6PP35: The size S6 frame is the load-bearing spec here — it tells you the contactor is built for higher continuous currents and larger cable terminations than the S0 or S3 frames in the same family. The stranded wire range of 25-120 mm² confirms this is a main-power contactor, not a control relay. The 200-277 V AC/DC coil means it can be driven from a common 240 V control transformer without an additional DC supply, though the AC/DC designation also allows a 277 V DC bus if your panel runs one. The screw-type coil terminals are standard for this class; no push-in or spring-cage option on the coil side. That helps when you're fitting it into a crowded enclosure and the gland plate or busbar layout forces an off-axis install.
