Rated for stranded cable from 70 to 240 mm² on the main power circuit, this contactor handles high-current motor feeds typical of pumps, compressors, and conveyors in heavy industrial environments.
Auxiliary switch is included on this variant — the screw-type terminals on the magnet coil accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). This covers standard control-circuit wiring without needing terminal adapters.
The 3RT1265-6AT36 has a listed depth of 206 mm, with a width of 145 mm and height of 210 mm — a Size S10 frame that fits standard panel layouts with adequate clearance for arc-chamber ventilation.
As a SIRIUS-brand industrial control component, the 3RT1265-6AT36 is covered by Siemens' standard compliance documentation including CE marking for the European market and UL/CSA listings for North American installations. RoHS and REACH declarations are available from Siemens' documentation portal for this order code.
