Product details

The Siemens SIRIUS 3RT6018-1BB41 is a size S00 power contactor with a 24 VDC coil, rated for motor switching up to 13 kW at 400 V AC-3 (at 60 °C ambient). The AC-3 rating (690 V max) covers squirrel-cage motor starting, breaking, and plugging duty, which is the typical load for conveyors, pumps, and compressors in a control panel. Coil holds at 24 V nominal; the 6 A figure is the steady-state draw at rated voltage — plan the DC supply headroom accordingly.

Panel integration — DIN rail footprint and wiring

Accepts 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm² solid or stranded.

Lifecycle and compliance — active production, documentation on record

Substance prohibitance date is 05/01/2012 — aligns with RoHS compliance.

Frequently asked questions

What is the closest functional second-source for 3RT6018-1BB41?

The peer 3RT6018-1AB02 is the same S00 frame with a 24 VAC/DC coil, so it drops into the same DIN-rail footprint and wiring scheme. The difference is the coil voltage type — 1AB02 accepts both AC and DC, while 1BB41 is DC-only. If your control circuit is 24 VDC, either works; if it could be AC, 1AB02 gives you flexibility. No rewiring needed for the power circuit.

What compliance documentation does Siemens provide for 3RT6018-1BB41?

The part carries a substance prohibitance date of 05/01/2012, consistent with RoHS compliance. The insulation voltage is rated 690 V and the degree of pollution is 3, meeting IEC 60947-4-1 requirements for industrial control panels.
