Mechanical and mounting
The 3RT1056-6AR36-0UA0: The contactor measures 172 mm high by 120 mm wide by 170 mm deep, and mounts via screw fixing with a vertical mounting surface that is rotatable ±90° and tiltable ±22.5° to front and back. The enclosure clearance requirements are 10 mm upward, 10 mm downward, 20 mm forward, and 10 mm at the side — tight enough for a standard 600 mm deep panel with gland plate clearance.
Termination and conductor ranges
The main power circuit accepts stranded conductors from 25 to 120 mm². The coil and auxiliary terminals accept solid or stranded conductors: 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or max 2× (0.75 to 4 mm²). The auxiliary switch is present on this variant.
Coil and switching performance
The coil operates at 24 VDC with a rated holding current of 10 A at 24 V. Switching times are 40 to 60 ms for both AC and DC actuation, with an arcing time of 10 to 15 ms. The contactor is rated for up to 800 operations per hour at AC-1, 750/h at AC-3, and 300/h at AC-2 duty. Mechanical life is 10 million operations typical.
