Product details

It carries a 24 VDC coil rated for 6 A holding current, and its screw-type terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire.

The AC-3 motor-switching ratings at 60 °C ambient — 7.5 kW at 230 V, 13 kW at 400 V, 22 kW at 690 V — define the real-world motor sizes this contactor can handle continuously without derating. The 10 000 1/h mechanical endurance (30 million typical) means it outlasts most machines in cyclic duty. The 690 V rated insulation voltage covers 480 V and 575 V systems with headroom.

DIN rail mounting and panel fill

The 45 mm width per unit means 17 units fit a standard 800 mm wide enclosure backplate.

Wire termination and torque specs

Screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded conductors. At 40 °C ambient, minimum permissible cross-section is 4 mm²; at 60 °C, it rises to 2.5 mm² — the higher temperature derates the wire ampacity, so you upsize the conductor to keep the connection cool.

Frequently asked questions

Where can I buy 3RT6018-1AR61 and get a price?

This contactor is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock count or price figure is published here.

Will 3RT6018-1AR61 drop into a panel built for 3RT6018-1AB02?

Yes — both are size S00, 45 mm wide, same DIN rail footprint and screw terminal layout. The 1AB02 uses a different coil voltage; the 1AR61 is 24 VDC. If the panel's control transformer and wiring support 24 VDC, it swaps in without rewiring the main power circuit.

What compliance documentation does Siemens provide for 3RT6018-1AR61?

The part carries RoHS compliance with substance prohibition date 05/01/2012. Siemens typically provides CE, UL, CSA, and IEC declarations on request for SIRIUS contactors.
