Product details

SIRIUS S00 contactor, 4 kW AC-3 — panel fit and ratings

The Siemens 3RT2316-1BG40 is a SIRIUS S00 contactor rated for 4 kW motor switching at 400 V AC-3 duty, carrying 9 A at 400 V. The S00 frame size keeps the footprint compact at 45 mm wide, 58 mm tall, and 73 mm deep, fitting standard 35 mm DIN rail per DIN EN 60715 with screw and snap-on mounting. Screw-type terminals on both the main current circuit and the magnet coil simplify field wiring. Solid conductors from 0.5 to 4 mm² and stranded from 0.5 to 4 mm² are accepted; dual-wire terminations are supported (2x 0.5…1.5 mm² solid, 2x 0.75…2.5 mm² solid, or 2x 4 mm² stranded). An auxiliary switch is built in, saving an add-on block for basic status feedback.

Sourcing and lifecycle — current production

RoHS compliance is documented with a substance prohibition date of 10/01/2009. The main circuit and auxiliary circuit both carry a rated impulse withstand voltage of 6 kV, supporting coordination in standard industrial panels.
