The 3RT5044-1AQ00: The main and auxiliary circuits both use screw-type terminals. That's a deliberate choice — screw terminals are field-serviceable, accept a wide wire range (2x 2.5 to 16 mm² solid/stranded, or 2x 10 to 1/0 AWG), and hold up to vibration better than spring-clamp in high-duty-cycle applications.
This contactor is built for a control panel — DIN-rail mounted, screw-terminated, with an auxiliary switch extension available.
Depth is 139 mm, width is 70 mm, height is 146 mm. It mounts on 35 mm or 75 mm DIN rail, and side-by-side mounting is permitted.
The substance prohibitance date of 03/01/2017 indicates RoHS and REACH compliance documentation is on file for this part.
