SIRIUS motor protection circuit breaker, size S00 — Trip Class 10, 100 kA
The Siemens 3RV2011-0GA10-ZW97 is a SIRIUS motor protection circuit breaker in the compact S00 frame, designed to protect motor circuits against overload and short-circuit. Its Trip Class 10 ensures rapid tripping under locked-rotor conditions — within 10 seconds at 7.2× the thermal setting — which is the standard for standard-duty induction motors driving pumps, fans, and conveyors. The interrupting rating is 100 kA at 400 V AC, which means this breaker can safely clear a fault current up to that level without external fusing in most industrial panels. That same 100 kA holds at 240 V, 500 V, and 690 V AC, giving you selectivity headroom across common supply voltages without derating the short-circuit capacity. It mounts via screw and snap-on onto a 35 mm DIN rail per DIN EN 60715, with any mounting position allowed. The S00 frame keeps the panel footprint tight — 45 mm wide — and the screw-type terminals accept 2×(0.75…2.5 mm²) solid or stranded, or 2×4 mm², with an M3 screw for the main contacts.
Lifecycle and sourcing
For a BOM line that requires this exact order code, we source it to order against an RFQ. Availability and current pricing are confirmed at quote time — let me be transparent, the cross-border supply route is clean on this one, same part, different passport, with full Siemens traceability.
Key ratings and what they mean for fit
The breaker includes phase failure detection, which is critical for three-phase motor protection — if one phase drops out, the motor draws higher current on the remaining phases, and this device will trip before winding damage occurs. Ground fault detection is not built in, so a separate ground-fault relay or RCD is needed if that protection is required. Temperature compensation is active across the -20 to +60 °C operating range, so the thermal trip curve stays accurate regardless of ambient temperature swings inside the enclosure. The storage and transport range extends from -50 to +80 °C. The maximum switching rate at AC-3 duty is 15 operations per hour, which suits motor starting applications but is not intended for high-cycle jogging or inching duty. The gL/gG fuse backup at 690 V is rated 6 A, providing additional short-circuit protection coordination where needed.
Integration and mounting
Clearance requirements: 50 mm upwards and downwards, 30 mm at the sides, and 0 mm forwards and backwards. This means the breaker can be mounted flush against a backplate or enclosure wall at the rear, but needs breathing space above and below for arc-quenching and thermal dissipation. The screwdriver shaft diameter required is 5 to 6 mm for the terminal screws. The design uses screw-type terminals for the main current circuit, which is standard for panel wiring and allows solid or ferruled stranded conductors.
