Product details

The Siemens 3RT2316-2BF40 is a SIRIUS contactor in size S00, built for switching three-phase motor loads up to 4 kW in AC-3 duty at 400 V — that's a 9 A rated operational current at that voltage. The coil is 110 VDC, with a pickup threshold of 0.8 x rated value (88 VDC) and a dropout floor of 1.1 x rated value (121 VDC), so it holds in cleanly on a nominal 110 VDC control supply and drops out reliably if the voltage sags.

Mounting and wiring — what fits in the panel

The main circuit uses spring-loaded terminals (cage-clamp style), accepting solid wire 2x (0.5 to 2.5 mm²) or stranded 0.5 to 4 mm². Auxiliary contacts also use spring terminals, same wire range.

Clearance and environment

Side-by-side mounting is allowed.
