Product details

The Siemens 3RU2116-0CB0 is a SIRIUS-brand thermal overload relay, size S00, designed for motor protection in control panels.

Mounts directly onto the contactor via the fastening method (contactor mounting), with no separate DIN-rail bracket needed. The screw-type terminals accept 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded copper. For the main circuit, use an M3 screwdriver with a Pozidriv PZ 2 tip, shaft diameter 5–6 mm. The 45 mm width and 70 mm depth fit standard S00 contactor footprints.

Ratings and ambient conditions

The auxiliary switch is integrated and rated for switching at various voltages: 2 A at 24 V, 3 A at 120 V, 2 A at 230 V, 1 A at 400 V, and 0.75 A at 690 V. Operating temperature range is -40…+70 °C, storage/transport -55…+80 °C. Temperature compensation is active from -40…+60 °C, keeping the trip curve stable across the panel environment. Power dissipation per pole is 1.6 W.

Frequently asked questions

What does the 'Note for message Tripped' mean?

That note indicates the relay provides a signal contact that changes state when the overload trips, so a PLC or indicator can detect the fault condition directly.

What are the key dimensions of this overload relay?

Width 45 mm, height 76 mm, depth 70 mm — it fits the standard S00 contactor footprint.
