The Siemens 3RV2011-0GA10-ZW96 is a SIRIUS-brand motor protection circuit breaker in the compact S00 frame, rated for a 0.63 A motor overload setting with Class 10 trip characteristic — meaning it will trip within 10 seconds at 7.2× the thermal setting, fast enough to protect standard induction motors during locked-rotor events without nuisance tripping on normal starts. Screw and snap-on mounting onto 35 mm standard mounting rail per DIN EN 60715, with any mounting position accepted. The 45 mm width and 97 mm cube footprint fit tightly into a motor control center bucket or standalone enclosure.
Breaking capacity and discrimination
Rated short-circuit breaking capacity reaches 100 kA at 400 V AC and 690 V AC — that is the full prospective fault current this device can interrupt without external fusing in most industrial distribution systems. At 240 V AC the same 100 kA holds. For a site electrical engineer coordinating protection, this SCCR headroom means the 3RV2011-0GA10-ZW96 can be applied downstream of a feeder breaker without requiring additional current-limiting fuses, provided the feeder's let-through does not exceed the device's withstand. Phase failure detection is built in — if one phase drops, the breaker trips, preventing single-phasing damage to the motor winding. No ground fault detection on this variant.
Termination and wiring
Screw-type terminals for the main current circuit accept 2× (0.75 to 2.5 mm²) solid or stranded, or 2× 4 mm². Screwdriver shaft diameter 5 to 6 mm. M3 terminal screws. The compact S00 frame leaves minimal finger space in a dense panel — plan terminal access from the front, with 50 mm clearance upward and downward, 30 mm to the side, and zero clearance forward.
