Siemens 3RV1011-0GA10-ZW96 SIRIUS Motor Protection Circuit Breaker
The Siemens 3RV1011-0GA10-ZW96 is a SIRIUS motor protection circuit breaker designed for motor protection, with a CLASS 10 trip curve that clears overloads fast enough to protect standard induction motors during start-up. Rated for breaking capacities up to 100 kA at 240 V, 400 V, 500 V, and 690 V AC — meaning it can safely interrupt very high fault currents without upstream fuses at those voltages, simplifying panel coordination. Mounts via screw and snap-on onto a 35 mm DIN rail per DIN EN 60715, and accepts screw-type terminals for the main circuit with conductor cross-sections up to 2x 2.5 mm² solid or stranded. Phase failure detection is built in — the breaker trips if one phase drops out, preventing single-phasing damage to the motor. Dimensions are 45 mm wide, 90 mm high, 75 mm deep, with clearance requirements: 20 mm upward, 20 mm downward, 9 mm at the side, and no clearance needed forward or backward.
Integration Notes
The 45 mm width fits standard DIN-rail spacing; the screw-type terminals accept 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or stranded conductors, M3 for main contacts. Operating temperature range -20 to +60 °C; storage and transport range -50 to +80 °C. Mounting position any. Rated voltage range 20…690 V; at 230 V the motor power rating is 0.1 kW. Maximum switching frequency at AC-3 and AC-3e is 15 operations per hour.
