Siemens 3RT2023-1NF30 — SIRIUS S0 Power Contactor
The Siemens 3RT2023-1NF30 is a SIRIUS power contactor in the S0 frame size, rated for switching motor and resistive loads up to the contact's thermal and breaking capacity. The coil is wound for 95 to 130 V AC, 50/60 Hz, with an inrush peak of 15 A and a holding power factor of 0.79 at 50 Hz, 0.74 at 60 Hz. Main contacts are rated for AC-3 duty at 16 A — the figure that governs motor switching in a standard panel.
DIN-Rail Footprint and Panel Fit
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width and 85 mm height with a depth of 107 mm fit the standard S0 envelope. Clearance: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side.
Coil and Auxiliary Details
Coil termination is screw-type. An auxiliary switch is built in, with rated values: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V. Operating temperature range -25 to +60 °C; storage -55 to +80 °C.
