The 3RB1246-1PG11: The 1.25–6.3 A current range covers small to medium motor loads (0.37–3 kW at 400 V typical). Class 5–30 trip curves let you match the relay to motor start-up time — Class 10 for standard motors, Class 20 for high-inertia loads, Class 30 for soft-start or long acceleration. The manual-automatic-remote reset gives flexibility: manual for commissioning, automatic for unattended lines, remote for PLC-based reset. The bistable output holds its state after a trip, so the control system knows the relay has operated even if control power cycles.
Deployment Context
The screw terminals on the auxiliary circuit are standard for panel wiring — no special tooling needed. The S00/S0 frame size means it fits the same footprint as Siemens S00 or S0 contactors, so it can be paired with them in a motor starter assembly.
