Product details

The coil accepts both AC and DC control voltage, so you don't need separate supply types on the same panel rail.

The 25–120 mm² stranded wire range on the main circuit is the critical spec for a panel builder: that's a heavy power lug, sized for incoming feeder cables or motor leads on a large drive or starter. The auxiliary switch is present and its contact ratings cover 10 A at 24 V, 6 A at 230 V, and 2 A at 48 V — enough for PLC inputs or pilot lights downstream.

The screw fixing method and 120 mm width mean it occupies a standard Size S6 footprint on the DIN rail or backplate.

Frequently asked questions

Where can I buy 3RT1456-6AF36 and how do I get a price?

We source this part to order against an RFQ. Submit a request with your quantity and target delivery window; availability and current pricing are confirmed at quote time through our independent distribution network.

What wire sizes does the main circuit accept?

The main circuit accepts stranded wire from 25 mm² up to 120 mm². For the auxiliary and coil terminals, solid wire from 0.5 to 1.5 mm² or stranded from 0.75 to 2.5 mm² (max 4 mm²) fits the screw terminals.

What are the auxiliary contact ratings?

The auxiliary switch is rated at 10 A at 24 V, 6 A at 230 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V — all at the respective rated values.
