Product details

The coil takes 380-420 V AC/DC, so it works on a common 400 V line without a separate control transformer — one less thing to carry on the van.

Mounting and wiring in the panel

Fastens with screw fixing — no DIN-rail clip, so plan for dedicated panel holes. The mounting surface can be vertical with +/-90° rotation or +/-22.5° tilt front-to-back, which helps when the panel layout is tight. Dimensions are 172 mm high, 120 mm wide, 170 mm deep — that 170 mm depth means it sticks out a bit, so check your enclosure clearance. Main power terminals accept stranded wire from 25 to 120 mm² — heavy cable for the S6 frame. Keep a 10 mm clearance at the side and 20 mm forward for arc flash and cooling.

Frequently asked questions

Where can I buy 3RT1456-6AV36 and how do I get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 3RT1456-6AV36's listed depth?

170 mm depth, plus 20 mm forward clearance for arcing and airflow.

What wire sizes does the coil terminal accept?

Solid wire from 0.5 to 4 mm², two conductors per terminal max.

Will 3RT1456-6AV36 drop into a panel specified around 3RT1264-6AP36-0KA1 without rewiring?

The 3RT1456-6AV36 is a different size S6 frame with screw fixing, while the 3RT1264-6AP36-0KA1 is a different variant — physical fit and terminal layout differ. Verify mounting hole pattern and power terminal spacing before ordering as a drop-in replacement.
