Product details

The 3RB1246-1EB01: The 25–100 A range covers standard IEC motor sizes from about 7.5 kW up to 45 kW at 400 V, depending on the full-load current. The adjustable class 5–30 lets you match the trip curve to the motor's starting profile — class 10 for standard squirrel-cage starts, class 20 or 30 for high-inertia loads like fans or crushers. The DC 24 V control circuit is common in modern PLC-driven panels, but verify coil suppression polarity if your output module uses sourcing (PNP) logic.

Integration Notes

The S2/S3 footprint matches Siemens 3RT2 contactors in the same frame size. The ground-fault signaling output can be wired to a PLC input for remote annunciation — no separate ground-fault module needed.
