Product details

The Siemens SIRIUS 3RT6018-1AB02 is a size S00 power contactor rated for AC-3 motor switching up to 13 kW at 400 V and 22 kW at 690 V.

AC-3 duty is the motor-switching rating that governs real-world use: at 400 V the contactor handles 13 kW, at 690 V it goes to 22 kW.

Mounting and wiring reality

Side-by-side mounting is allowed with no derating gap. Terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded. At 40 °C the minimum permissible conductor is 4 mm²; at 60 °C it drops to 2.5 mm² — the higher ambient demands a larger wire to keep the connection cool.

Sourcing this part

This is an active Siemens SIRIUS contactor sourced through independent distribution.
